120W LED + Rainforest 66 + Papaya

[dman0042]

Oh yea are you able to switch on the the LED's in separate order? Like just blue or red or white at one time?

 

[206]

Can you take another photo of the big one with no led just regular. Just to see without the color of the lights.

Also how old is the big one in thumbnail 1?

Below are some more pics with leds off. The big one is 16 days from seed breaking ground.

No but that would be an interesting feature I suppose, especially if the color of each bulb could be changed on the fly.

I have also germinated one thai super-skunk freebie just to have another strain to experiment with.

Day 17 pics added below. I plan on flushing the res within the next 48 hours and will switch from GH grow to fox farm grow big (hydro) at that time. I will still keep feeding GH micro as well and also plan to increase the feeding schedule.

Day 18 pics added.

Pic 1: Papaya #1 (day 1
Pic 2: Papaya #1 roots (day 1
Pic 3: Papaya #2 (day 3)
Pic 4: 48 hours ago I germinated papaya #3 and thai super skunk #1
Pic 5: Super skunk 48 hours later (day 2)
Pic 6: Papaya #3 48 hours later (day 2)
Pic 7: I found about 20 bag seeds which I had lost a year earlier. I have no idea what strain or strains they came from but I began germinating 2 of them for experimental purposes.
Pic 8: Bag seeds in humidity dome

Today I dumped the res and did a thorough cleaning before refilling. I also switched up my nutes to fox farm big grow + gh flora micro and raised to 600 ppm. I didn't want to go any higher right now because I have some younger seedlings in there.

Pic 2: Papaya #1 roots (day 19)
Pic 3: Pic from shortly after res change.

thought you might be interested. these are new and made by a single company. looking more into it.

the quality looks amazing. huge billet alluminum heatsinks. but pricey i think. havnt found the price yet.
check out the lifi site for the pics. there looking healthy still. cant wait for a month or so to go by.

The big plant responded well to the res change and new nutes. I had the res PH sneak up to 6.3 this morning but I caught it and lowered back to 5.8. I should have done the res change earlier in the day to make sure the PH was stable before I went to sleep...something to remember next time for sure.

I just have to say again that after 20 days I am amazed with the growth. To all the LED doubters saying they create stretchy plants and can't penetrate, just look closely at pic 1 and remember that is 20 days from seed and using 135~ watts of electricity for the whole setup.

Pic 1: Papaya #1 (day 20)
Pic 2: Papaya #1 (day 20)
Pic 3: Papaya #1 LED off (day 20)
Pic 4: Papaya #1 (20 days ago)

Any comments are welcome!

Looks pretty interesting but IMO is years away from being affordable for us. Very cool stuff though and thanks for checking in on the grow.

just to let you know i looked closely at your growth. it looks to me that your light is keeping up fine. the plants look def a great size for 120 watts. i keep forgetting to account for that. mine were just slightly bigger at the same time frame and were under around 500 watts. i have 12 plants. if i had 5 and 120 watts of t5ho i dont think they would look like that. def watt for watt you are at least keeping up with hps. i actually had some doughts but the nodes are not stretching. they are short and stalky. I now totally believe in the leds for growing. def an efficient light. you prob dont need as much penetration when more of the light is being used by the plant. they def look like they enjoy it. cant wait till you start to flower but it def seems like you could easily get more than .5 grams per watt. looking forward to seeing. And those lights are crazy. they should be out any time. i'm looking into them seriously. The only rerason i want reg coloured leds is so they can go over my aquarium after.

hey 1982! I like your posts. Do you don't know the price for this bulb yet? It's impressive!

However, have you seen this?


I'm a little concerned about the large drops in blue and red radiation, as well as the very high green. The LIFI-02 is better for the red. Green light isn't good for seedlings/vegging as it causes dramatic stretching. Maybe for flowering though... I would love to try one out.

Also, the cnet video says they are using 250w, which is significantly brighter than the 400w light they compare it to. But why 250w? Is that the watt for their light? They said the plasma gets 6000K!! That's like... nuclear fission temps haha

As you know I've been following your progress It looks real good. I'm curious how high you are trying to leep the LED above your plants, and how high you would like to, if it's different

from what i see in the video. the spectrum looks around 10000k. i know its 250 watt because in canada we are trying to switch them all out for lower wattage from 400s. 3 250 watt 1s would be insane. i think the 6000k you are talking about is the colour. which is actually great for veging. if they make a low kelvin model wed be set for flowering. but the good thing is most lights do come in 3000k. i dont think the 6000k was temp. hps gets around 450 degrees for the bulb. even if this 1 gets slightly hotter which i dont think it would, it would radiate heat easily being so small of a bulb. i'll have to check out that model youre talking about. ive also been looking at luxeon k2s. they look promising. i should have some money soon to. my grow is going much bettr than expected. cant wait. been harvesting for the last week. at 100 wet grams so far with at least a 1000 to go. i'll def buy some sort of homemade upgraded light. leds or plasma.

dont let this thread die!!!!!!!!!!!!!
I was very interested in that light. There is a lot of confusing info out there about leds.

Sorry for the lack of updates, I actually had to leave the plants alone for 7 days. Before I left I raised the light 24" above the plant and set the ph to 5.2. I fed flora series to 500ppm. On day 4 a friend was able to balance the ph for me. He reduced it from 6.3 to 5.4. I just got back a couple hours ago and increased ppm to 650 (going to drain and refill again soon) and reduced ph from 6.1 to 5.8.

The growth in the last 7 days is nuts, I'll let the pics speak for themselves:

Thanks for posting again. I think im gonna get that light. It seems you are proving that new generation LEDs can grow bushy thick stalked plants. Do you feel like the light is living up to all the hype on the HTG website? Could your plants really grow right into it without burning? Thanks again.

For vegetative growth, the LED has lived up to the hype and surpassed my best expectations. I obviously can't comment about flowering yet but I am expecting big results (400w+ HPS equivalent) there as well.

I haven't pressed the light against the plants yet, but I would feel totally comfortable doing so. They have been as close as 2" so far with no problem, although I keep it about 18" above right now since I have other plants going.

 

[206]

I also just wanted to note that the LED managed to grow those thick stalks without any help from fans. I have been ready for weeks to hook up a fan at the first sign of droopiness or thin stalks/stems but so far there has been no need. This will probably change during flowering but just FYI.

You're gonna flower with that thing? Node distance is already pretty far, maybe it'll yield a touch above CFL's but nowhere near HID lighting. Anyhow, good luck.

awww... and the reason I haven't started an LED thread pokes it's evil head. Too many haters. I suspect there are more LED growers who are keeping their results to themselves...

Great job 206 keep up the good work!

I cannot wait to see how the flowering works out for you. I am flowering with a 350w LED panel, but my plants get that for 4 weeks and finish under a 1000w hps for another 4 weeks. Also have had great success with vegging under a tri-band UFO.

Pssh, I'm not a hater just a realist, tho I'm just as curious to see how this grow turns out as anyone else. For 120 watts it is phenomenal, I just don't think it'll cut it for flowering, but we shall see. Whatever scale you grow on and with whatever lighting, it still beats paying street prices for inferior smoke. So we're all winners in the end.

Thanks for the comments guys.

I took 3 cuttings from the big plant today and will probably take 1-2 more by mid-week. I also measured it for the first time and it is 14" tall and 23-25" wide depending on where its measured. For perspective the tent is 32"x32"x60".

I haven't done a very good job documenting the other 4 plants in the rainforest so I wanted to do a recap. Keep in mind that since Papaya #1 is so far along, the light has been 2-3 feet off the smaller plants for their entirety.

Pic 1: Papaya #1 (day 31 from seed)
Pic 2: Papaya #1 cuttings
Pic 3: Papaya #1 cuttings
Pic 4: Thai super-skunk (day 13 from seed)
Pic 5: Papaya #2 (day 14 from seed)
Pic 6: Bag seed #1 (day 11 from seed)
Pic 7: Bag seed #2 (day 11 from seed)

Thai s-skunk looks very healthy so far and already has more odor than the papaya #1. For an outdoor sativa it really doesn't look much different than the indica papaya so far.

Papaya #2 has been a very slow grower compared to Papaya #1 in its first two weeks. It also has slightly deformed leaves, but I'm not giving up on it yet.

Both of the bag seed plants are completely covered by several layers of leaves from Papaya #1 so they get mostly reflected light. I will be transplanting these to a smaller hydro system in a few days.
