Extreme Flowering Under Pair of Timber 48SAMS

[Randomblame]

so in the next round youre gonna use the 2ft agro from day 1 ?

I will try to use them from the beginning with the spreaders in front of the bulbs. Probably at around 32 or 34", I must see what height is possible now, and only for 5+5 minutes.
Every 3rd day they will get 5+5 minutes more until they get at least 2+2h. Will upload a picture every now and than to keep you guys updated. Maybe its possible to use them from the beginning without gettin' too much issues.

With a few modification on the circuit design I have 325w now from strips and COBs. Rewiring and driver case completed, all is working as intended. Girls get transplated later this day and hardening program starts tomorrow. Plants are not used to UVB till now. They vegged under a 60w fixture with no UVB. Pics will follow tomorrow if it's okay to high-jack your thread, bro.

Plants looking yummy, btw. I like the purple diesel buds. It's really nice how LEDs help to bring the colors to life. Did they smell like petrol?
1st haze seems already a good yield and the 2nd SSH lady seems to be even better. Its not the baby leg pheno but both hazes are for sure good candidates for cuttings with no veg.

High-jack away RB.....beautiful craftsmanship, man....german engineering!

Btw, how many nodes do your plants have at the start of uvb?

Speaking of re-wiring, i’m gonna have to have an electrician out to put in some additional circuits in my grow room, so i can handle the load of the lights, fans, hvac, etc. for the 288 vs 96 smackdown....holiday project.

I love that purple, too, especially the smaller front one being offset by the lighter color leaves.

Like we discussed earlier, they may not even be diesels, unless that strain has a pheno that smells like wrigley’s juicy fruit chewing gum. Lol!

The remaining haze is obviously larger with diff bud architecture and structure. The buds on the top two feet feel and look like miniature pinapples, the ones deep down are a little softer, but still firm. That plant could perhaps yield over 1 pound.

Both hazes smell similar, with the primary aroma being that particular hazy smell (almost like pencil shavings/incense cedar) that i don’t particularly care for....but i love the bzzzz.

I’ve been fortunate to not have any major problems this grow.

Thinking probably 2-3 lbs of pretty and potent bud. We’ll see.

I will be propagating and vegging the victims for the 288 vs 96 smackdown under hlg 96 light(s).

I don’t expect much excitement about that; if you are interested prior to 12:12 you can find out more at https://forum.grasscity.com/threads/hlg-288-vs-96-smackdown-grow.1524965/#post-24414719.

At some point prior to 12:12, i’ll set up an extreme flowering thread on riu.

Usually they get UVB from the 2nd week. This time it takes a bit longer 'cause I meanlined them in another old 3ft² tent with no UVB and only 60w. They have already 8 more or less equal mains each with 3 nodes. I'll let them root for a while before I bent them down to equal heights. They are already transplanted and got their first 5 minutes todays morning (7am) and the 2nd in the evening(10pm). Distance currently is 34-38" and every 3rd day they'll get 5+5 minutes more UVB. Wanted to take a shot with UVB still running but 5 mins was to short and right before I have taken the shot it switched off, lol! Damned alarm, I have to set it a lil' earlier for tomorrow.



I'm already curious for the 288 vs. 96 smackdown and subbed it already in my mind.

Nice, healthy looking plants. Those are only 3 weeks old? From cuts or seeds? It usually takes me 3 - 4 weeks before 1st topping.

Thanks for the info and pics, keep us updated.

Can’t wait to get these flowering:

Day 82: My chopping arm is quivering...

Ppfd ~1050, controlled variables in range.




Here’s just another reason i love 1000ppfd and tulip-shaped plant center, view from 24-36” below haze’s canopy top:



A tad softer buddage, trichs a few days behind.

Nope, they are around day 55 or so. Do you remember the 5 girls I have shown a few weeks ago? SSH, BlueDream, ColumbianGold and 2 own BD crosses? That's these 5 ladies.
I first had two nodes with branches left on each plant and last week I removed the bottom ones to have 4 clone of each plant. They are currently in the cloner and need another week.
After this test I will keep only one or two genetics to work with.

I have by the way calculated how much kJ/m²/h you get from 1μW/cm². 1μW/cm² UVB means you get a dose of 0,036kJ/m²/h.
This way you can use your device measurments and simply multiplicate the readings by 0,036.

The way how I figured this out is pretty easy to understand...

When 1w is 1Joule than 1w/cm²/s is 1J/cm²/s, converting to μW is the next step.
1μW/cm²/s is 1J divided by 1million so 0,000001J/cm²/s, next step is how much is it per hour.
0,000001J/cm²/s x 3600sec(1hour) = 0,0036J/cm²/s. Now convert it for m²..
0,0036J/cm²/s multiplicated by 10.000cm² = 36J/m²/h, and now for kJ...
36J/m²/h divided by 1000 is 0,036kJ/m²/h.
So from 1μW/cm² you'll get 0,036kJ/m² UVB every hour.

At two ft. distance we should have 170μW/cm²/s with reflector so one hour would be a dose of 6,12kJ/m²/h. The UVB pdf says they've used 6,7 and 13,4kJ/m² and found linear increase in thc. This means you need only a little more than 2h with the Agromax bulbs at 2ft distance to get the same dose. I will try to give them at least 3h the day or ~20kJ/m² when compltely used to it.
I've use much more already with the reptile bulbs but their UVB ends just below 300nm. Agromax and Flowerpower bulbs go as deep as 280 or maybe 275nm(pretty hard to figure out with the Agromax spectrum chart) and this can make a huge difference. The lower the wavelength the more damage.
This could be the reason why these bulbs are more stressful.
I've used at least 120μW from reptile bulbs(1ft distance) for the whole 12h and this would be a dose of 51,84kJ/m². Almost 4 times as much like 13,4kJ and got no damage or stress symtomes beside slightly curling leaves in the first week.

This ladies got another day with 5+5 minutes UVB, 30klx intensity at canopy level, 270w and ~3ft distance. I can see no damage till now. One plant(front left) had a slight magnesium deficit but its already fixed and new growth is healthy. I have only the feeling the leaf margins are slightly curled upwards but only a very little till now.

Thanks for the step-by-step calc.

Those girls look great under light blue light...

For plants you started on uvb early, how many nodes did they have?

 

[Randomblame]

Usually seedlings with 2-3 nodes and cuttings as soon as transplanted. This time later because the implementation of the two 24w bulbs with new reflectors and the new driver housing takes some more time. But usually as early as possible..

 

[Or_Gro]

Day 83: Began flushing the big haze today. “Diesels” start coming down this weekend; big haze tops early next week.

Bumping my expectations to 3-4 lbs....Smaller haze weight tomorrow.

Ppfd ~1050, controlled variable in range.

Hey @Randomblame, if i wanted to push veg into higher gear, what spectrum nm would you recommend, in what quantity? Other recommendations. I will still be doing manifolds, but want to speed up arrival at 12:12. Danke

 

[Randomblame]

Morning, brother! I would say 5000-6000°k has the highest growth rates in terms of green mass and it forces the branches to grow faster. You'll get really tight nodes spacings and plants are becoming wider cuz the branches grow almost horizontally at first.(70-80° to the main stem). Leaves stay a little smaller but you'll get more of them and more nodes in the same time.
Basically, it takes more blue-cyan wavelengths (430-495nm) to turn 3000°K into 5000°K. But I have not tried it yet so you would have to try how much it takes. Maybe 10-20w in addition to any E96 puk.(at 200w).

Thanks, horizontal growth during manifold creation, would work well. I’ll look into it.

I harvested & trimmed the other half (4 mains) on the front haze today. Here is the evidence....

We’ll see, but guessing 1/2 to 3/4 lb for this plant....

This plant totaled 304.5g/10.9oz, not too shabby...
