Jack 47 Fast (Sweet Seeds). Soil, Indoor Tent, LED

Pictures below the following wall of text.

Plan:
- Two Jack 47 F1 Fast (Jack 47 x Jack 47 Auto, PHOTOPERIOD). Seedling 1 week, veg 3~5, bloom for 9. There have been a few soil grow journals online for this plant... I think I'm looking at 55-65 days of bloom. With half a square meter of space, I hope to get 7-8 oz, with an expectation of at least 6.
- Will LST as necessary, other than nute issues, my biggest mistake last grow was underestimating stretch. My hope in buying these seeds was that I could get a low profile Sativa. I've only got 5' of space, allowing for maybe 3' of vertical growth max.

History:
-One grow with autos, I got 3 zips of crap and 1 zip of decent indica. I felt like I did everything wrong, but one of them was a super auto (I had to cut early at 14 weeks). FFOF & Fox farm nutrients, I didn't handle the transition of my FFOF running out of nutrients very well.
-I decided to grow because it's fun, cheap, and safer than going through a dealer in my area. Plus, I'm from Seattle, my standards are too high for this east coast crap.

Equipment:
-2x2.5x5' Gorilla Shorty
-Phresh air filter + cheap inline fan with speed control
-P150 LED (50w Veg, 90w draw in bloom) & Will add two Bridgelux Vero 18 Decor 97 CRI at 30 watts during bloom. This light has been talked about a lot, basically it's a cheap chinese LED with good blues and bad reds, hence the addition of two 30w CoBs.
-Tap water is run through a Brita filter to make it EC:.3 & pH:6.5. No chlorine, 3 ppm of Chlorium. I figure it's extremely low and the Brita helps.
-5 gallon smart pots (2)
-Heavy 16 Veg, Bud, Finish, Prime
-Aptus Fasilitor, Startboost, Ecozen, Bloomboost (Massboost, Finaleboost, Peakboost didn't seem to have anything special)
-House and Garden Roots Excelurator
-Grow More Sea Grow (P-K booster). Heavy 16 bloom is 1-1-3, I'd like to add a little bit of P.
-Roots Organics Extreme Serene (Kelp & Soapbark)
-Advanced Nutrients Big Bud, Bud Blood, Piranha, Tarantula.

Each 5-gal made in the following order:
-Dozen or so slits in the bottom & four larger (1" diameter) holes in the bottom corners; using black and white plastic (panda film) as my trays... space is too narrow for legit trays
-1 quart perlite layer at bottom for drainage
-4 quarts FFOF, perlite (miracle grow, sorta rinsed), small handful of dolomite (tablespoonish); Mix these together
-4 quarts FFOF, perlite (Espoma, Organic - not rinsed), small handful of dolomite (tablespoonish); Mix these together
-5 quarts FFOF, perlite (Espoma, Organic - not rinsed), small handful of dolomite (tablespoonish); Mix these together
NOTE: The top layer of the soil has the strongest mix because of materials available, I ran low on perlite.
- .45 quart FFOF, .45 quart perlite, .1 quart vermiculite; mix these in a 5" hemispherical hole
-Rinsed with 5 gallons of tap water (150 ppm, 7.5-7.7 pH); both were fairly wet, but nowhere near dripping wet on day 0

--------------------------------------------

Day 0:
Half gallon of water mixed between both
-1ml piranha & tarantula
-.5ml startboost & ecozen

Added a small handful of vermiculite & perlite and mixed on top of the soil.

Day 1:
Both germinated in a paper towel within 24 hours, planted less than an inch deep

Day 2:
Keeping humidity 70-80%, spraying general area every 6-12 hours.

Day 3:
Still no sprout, lowering humidity to 65-70%

Days 4-5:
Both sprout. And so it begins.



Day 6:
Gave combination of .5 ml Roots Excelurator, 2ml of AN Piranha, 2 ml of AN Tarantula, Aptus Startboost, .5 ml Aptus Ecozen, .5 ml Heavy 16 Prime
With 1/2 gallon mixed between both, circled/squared around plant, 3" radius, teensy bit directly on.

Day 7: looks good

Day 8: Watered half gallon each with 2 tsp of bigbloom each

Day 10: They look good, maybe tiny bit of curling, maybe fast growth; humidity 55-60% (follows with watering)

Day 11:
H&G Roots Excelurator - .5 ml per half gallon
Aptus Fasilitor, Startboost, Ecozen - .3, .5, .5 ml per half gallon
H16 Prime & Finish - .5 & 1.25 ml per half gallon, respectfully
AN Piranha & Tarantula - 4 ml per half gallon
All minus Finish in first half gallon
-Share half gallon (1/4 G each) of Finish



Day 13:
Looks good



Day 14: Water with 5ml of big bloom in each half gallon... half gallon of water to each

Day 15: Looks good, some cupping

Day 18:
3 half gallons, one EACH of:
H&G Roots Excelurator - .5 ml per half gallon
Aptus Fasilitor, Startboost, Ecozen - .3, .5, .5 ml per half gallon
H16 Prime - .5 ml per half gallon
AN Piranha & Tarantula - 4 ml per half gallon
Share 3rd half gallon:
H16 Finish - 1.25 ml
-Share half gallon (1/4 G each) of Finish

Day 21:
Added a tad bit of water to each, directly on top

Day 22:
Looks good, the bottom of each smart pot is still damp, I'll let it get a little bit drier to help the roots fill out the pot. As one can see, the plant on the right is significantly smaller than the plant on the left. However, the plant on the right (smaller one) is drinking a lot more water. I expect it to explode soon or stretch significantly more. My first nodes are basically at ground level, great use of space.


Look at my node spacing! Combination of FaSilitor & low lights. I foresee a couple of bushes in my future.


Comments are welcome.

Im interested in this strain and company. Looks like im aboard for the grow.

Day 24:
1Gal shared equally:
H&G Roots Excelurator - 1 ml per gallon
Aptus Fasilitor, Startboost, Ecozen - 1, 1, 1 ml per gallon
H16 Prime - 1 ml per gallon
AN Piranha & Tarantula - 4 ml per gallon

Day 26: Look good.

The strange one is strange (one on the right). The root and/or early stem development seemed to grow sideways for the first few days rather than straight up. I am a new grower... but I did nothing different between them. We'll see, it's just a little bit smaller than the other.

They're both looking good and drinking as much as you'd expect. New node development is progressing, but has slowed down, and they're starting to stretch out a little bit (lights are still 21/3).



Day 28:
half gallons EACH:
H&G Roots Excelurator - .5 ml per half gallon
Aptus Fasilitor, Startboost, Ecozen - .3, .5, .5 ml per half gallon
H16 Prime, H16 Finish - 2 & 1 ml per half gallon
AN Piranha & Tarantula - 2 ml per half gallon
.1 gram of Sea Grow, 4-26-26 (I'm showing absolutely no signs of N deficiency yet & I wanted some micronutes, hence I think I wasted money on my veg food)
Half gallons EC before: .227 & .262;EC after: .358 & .390

Day 33:
Gallon w/16ml Big Bloom, half gal each

Day 34:
Added 35w of 3k light (Bridgelux mentioned above), I'm waiting on another heat sink to arrive. Sorry for the colored light pictures, it looks a lot more normal to the naked eye (with UV goggles). I have flipped my lights and started some light LST, let the tying down begin, I really should move to a scrog.

I have forgotten to mention. My temperatures vary from 67-77. Not a whole lot at all, but the addition of 60-70w more light (via the CoBs) may change things... but I'm also turning on my carbon filter so there will be more airflow. I will add a second CoB in three days (shipping delays, I had doubts whether I could make one myself).

Essentially, my temperature variation isn't much and CO2 levels vary between 800-1300 at night and 400-700 during the day (multifamily housing). So... I'm going to have my plant's daytime cycle begin at night.

Roots... roots abound.
Note: I previously said Day 34 was the day I flipped my lights, I lied and can't edit. Day 34 is the day immediately after I flipped my lights, the first day of flowering.

Day 1 flower, Day 34
-New growth is lime yellow, with some of the older growth as well. Diagnosed as N (unlikely), Ca (medium likely), S (most likely): all of which would be fixed with my base nute. Maybe fed too much, too strong, but I won't kill it with one slightly high feeding. Forgot to pH, dropped the ball on that one. Probably not Fe, but maybe, will get some of that with my sea grow in three days.
1/2 gallon shared
3mL bud blood
2mL each H16 bud
.232 before
1.14 after

Day 2 flower:
Adding 30-35w more LED (another decor)
Ordered two 3590's, bin CB, will run at 50w each to replace p150... or just add on top of it.


Good to see development:


Day 3 flower:
Still some yellow, I don't think it's too bad, will feed tomorrow. Lots of extra sulfur in H16 nutes, it should figure itself out.

False CoB+p150 light:

Roots finally show, yay.

LST pics, each of these pictures is 20-24 hours after the previous one.
- Flower day 7 (fed this day)

- Flower day 9

Fed again on days 4 and 7 of flower... EC's of 1.7 & 1 (starting at .2)... pH hovers between 5.5-6.0 (dolomite lime & AN piranha/tarantula every other feeding).

I was afraid that jumping up to such a high EC immediately would not be good... but I haven't seen any damage yet. Maybe I caught the FFOF running out of nutes perfectly?

I'll be adding my final two 50w 3590 3000K's. I'll have four 3000K cobs (30w x2 + 50w x2) and my P150 making sure I have enough blue. My light will pretty much be coming from every point above the plants (and the sides via Mylar). 250w of mostly high quality light in less than 5 square feet of space.

Days 11, 12, and 13. My 250w put off way too much heat... so I now have 90w of shitty LED light (continuous spectrum, it's there for UV), 100w of 3590 3000K (CB bin, 80 CRI), and 31~33w of Vero 18 3000K (97 CRI). 220w in 5 ft^2 (closer to 4).

I've had a humidity and airflow problem. I will usually look at my plants / water my plants in their morning as soon as the lights come on. I've noticed some water droplets on my plants a couple of days after a feeding. You can see a couple of small holes on my leaves... these are presumably from droplets that magnified/burned a tiny hole. Almost all of these little holes are slits rather than gaping holes and they are at sporadic, non-localized, parts of the plant. Therefore, I have deemed there to be no infestation, so little burnt holes theory should be true. Or my airflow is THAT bad and they were on the plant for days. Either way, I'm working on humidity.

I get better, more focused, pictures with lights on. The last few pictures are lights-off pics, the colors are good... but still no REAL stretch two weeks in. Remember, this Jack 47 was crossed with an Auto, so maybe the ruderalis is kicking in.

- Day 11
- "I'm hungry" Day 12 (fed this day)
- "Yay, water and food" Day 13

Stretch has begun and it's pretty obvious I'm dealing with two different phenos... with the one on the right being indica or even ruderalis dom.

- Day 14
- Day 16 (left flower is leftmost plant, right flower is rightmost plant)

Flowers starting to form, stretch is very tame.

- Day 19
- Day 20
- Day 21

The one decent grow journal I have found has stretch ending at day 28ish in soil. I really hope they add another few inches... stretch hasn't been as high as I wanted. I'll have at least a foot of wasted space above my lights at this rate.

Day 21 (for comparison)
Day 26
Day 28 - (left pic is left flower, right pic is right flower)

General: I've got three or four decent colas on the left plant... but the one on the right is showing a decent amount of apical dominance, maybe a second cola that'll be sandwiched with the wall (I can fix that). I've got a tiny bit of nute burn, it only showed once and it stopped spreading. I think they have finally finished stretching and begun putting on weight.

Feeding: They're drinking about .75 gallons each every 48 hours. I mix a gallon to EC=2 and share it between both plants equally... then add pure water (with a bit of big bloom / extreme serene) until I get a tiny bit of runoff. Every 4-5 feedings it gets pure kelp. So I'm constantly feeding at around EC=1-1.5ish. I don't pH my water (I add beneficials, going for a quasi-organic thingy).

Light: My light situation is weird, I basically have my 90w P150, two CXB3590 @50w each, and two Vero 18 3000K at 30w. 110w of the CoB light is over the plant on the left while the plant on the right has only one 3590 above it; they share the P150. 240W of LED in 5 square feet is very high, so I don't think the plant on the right is really missing out on much since the CXB/Vero18's have a very wide display angle. I expect some thick ass buds from the plant on the left... but I've got to improve airflow.

Lastly... Aptus Bloomboost. This stuff bumps my EC up .15-.25 per ml (in a gallon). Their video states that it has L-amino acids, polysaccarides, and "natural plant biostimulants" (aka hormones?), and vitamins. I'm pretty sure it sorta doubles up with my H16 Prime and kelp products... but what the hell.

Looking great so far!

Day 28 (for comparison)
Day 35 Real light (can't focus correctly without lights, but it's good to have these)
Day 35 - Five days without food, gave each a half gallon of straight water the night before. Stems are also kind of turning purple/red in addition to some dead leaf issues at the edges of older growth, so I think it's P. H16 is 1-1-3 and I've been slow at adding Sea Grow (basically 0-1-1) to it. I gave it a boost of Hawaiian something (0-5-1) and will probably continue doing so until I stop feeding.
Day 38 - Although the leaf issue is spreading, I feel like it might just be a delayed reaction and will give it another week. It's probably just throwing a tantrum because I left it for four nights. I'd put it at a 25% chance at it being nute burn, so I'll be increasing P and runoff at the same time.

Overall report: Despite their slight physical difference, they eat the same and smell the same... sour, earthy, taste of mint. Even if I'm starting to experience nute burn, these puppies have taken a lot of nutes. I basically give them each a half gallon of E=2-2.5 feeding every other day... then top off with maybe a quarter gallon each of some organics. There is one real grow report out there for this strain and I appear to be on schedule, if not a day or two behind (probably because of LST and/or flower day count start).

Light: At the beginning of my grow, I decided to focus more light on the left plant and it appears to be producing more with solid penetration. I figured that the ruderalis-dom would be inferior, but it's packing on bud pretty well.

Air flow: This is hard in small cabinet grows, especially when you get a dense canopy. I basically have three fans blowing at the base of my plants in a counter-clockwise direction around my tent. Humidity is controlled to the best of my ability... mid 50's. Dehumidifier is running 18 hours a day at a cost of $10 a week... 4x more than my lights. I'm not in this as a "business" and I make good money, but it still bugs me when I have to turn it on.

- Day 43
- Day 46 (picture on the left is flash-only and was the only one to properly focus)

You can see notable decay between just these days alone... I have been dealing with what I presume to be nute issues and the fact that the plant is dying doesn't really help things. Water with an E=.3 and pH=6.5 had runoff of E=3 and pH of 6.3... so a lot of nutes are still in the soil. I'll be giving it pure water from hereon out, with maybe some molasses and my Aptus Bloomboost.

- Day 51
Day 57
Day 58 - Harvest day, I took shit pictures so these are the three best I have.

I had a pretty strong nute issue at the end of things. I was faced with just giving them pure water or flushing (shocking it) and giving them some fresh liquid nutes in the final two weeks. I chose to just let them die with water. Personally, I think I had a K tox, but it was a general calmagsulfur issue imo. I'll lower nutes and increase calmagsulfur next time, I really was overnuting.

I only harvested the smaller plant and wet weight came in at 486 grams wet of bud + stem trimmed. I actually forgot to get a money shot and it's in a dry box in my tent... sorry. Although the plant is very small, the buds are hard as rocks. A gentle squeeze has absolutely no give whatsoever. I really should have gotten an after-trim shot... I was just so freaked out by the weight total. By size, I was expecting an ounce, this thing should bring in about three ounces, I am ecstatic.

With that said, the other, bigger, plant has much more airy buds. Remember, sativa dominant hybrid. However, airy is fine if they're big enough. I bet I will get a QP or more out of that one. Am I actually going to hit half a pounce in 5 square feet (more like only 4 utilized) and only four weeks of veg? That would be amazing. Also, with all this trim, I can make some more gummies. Edibles are stupidly overpriced. Big girl should get harvested on day 61-62. I scouted out one amber on day 57... looking at several flowers. A few more days or even a week should do it some good... the side lighting should help fill in the ends.

I apologize, I had to take out the best picture because it has identifying information on it. That first picture on day 58 is about 2/3 of the plant... I wanted to show my light penetration.

26 hours after chop...



I didn't notice how underdone some of these buds were. About 5 inches below the canopy, it's MAYBE in its first week of harvest with no amber. If I had a bigger op (more than one filtered space) then partial harvests would be the better move. The second one weighs 28 grams after one day of drying, it's probably a half ounce nug.

The other plant will take at least two more days. I might even let it go another week, it's not maturing as fast as I thought. The only grow journal I could find, the one that's made by Sweet Seeds themselves, had 63 days. That totally makes sense. Each top is starting to turn amber... very slight but it's there. I could probably harvest right now as I've got less than 10% clear, but I'll let the tops get slightly overdone. I'm going to separate the "well done" from the "barely done" and see which I like more.

This growing thing ain't so bad.

I had to harvest a couple of days early. Still in the grow window, but ideally I would have waited another week... but I've got a schedule to adhere to. I got lazy with trimming, but I feel like I did a pretty good job for a guy with a sore neck.


- Main stem... the "apically dominant branch" if you will
- Top two branches vs. 20 oz vitamin water
- Dry area with each of the three hangers exhibited

620 wet grams with stem. Everything you see in the last pictures above weigh 620 grams.

Combined wet weight eclipses 1100 grams. I harvested two days after my last water (I watered every other day) so I'd assume it isn't flush with water. 75% loss + stem is probably a safe estimate. This is 11.6 ounces... so 11-12 ounces. Worst case, I'll see 9-10 ounces which is more than I had hoped for. My plan is to smoke the well done and cook/vape with the lower branches. We'll see.

I'll be back in a month with dry weights and smoke reports between the phenos. I "ran away" from the ruderalis dom by focusing light on the bigger plant. However, the bud on the bigger plant is much less dense... so much that the ruderalis dom might actually have a better harvest per area. Furthermore, I kind of screwed up feeding the bigger plant and its buds haven't swelled as much as they seemed like they should have, so I have no overall judgment. If you get this plant, do not throw away the ruderalis dom midgets.

Leaves can easily look burnt when they are in fact starving. Food for thought.. only you really know what your schedule looks like though.

Thanks for commenting, it's something I will be doing some research into. For the time being, aka next harvest, I'm doing 3 gallon (smaller) with the same soil-perlite mix and an extra kick of dolomite. I'll reduce my relative nutes, but give it a shot of Epsom twice in flowering. I'm pretty sure I have the tools, it'll just be a matter of figuring out the right ratios.

Interesting report, as I've just purchased 25 seeds of this strain for my next grow in a month or two.

How is the smoke????

I see a few things I would have done differently to have a healthier grow, but I don't want to impose on the grow report unless you want some suggestions.....
