Ya, I got them off Ebay last year. If I remember right, i paid about 150$. I might pick up 2 of the all blue panels just for budding. I read that they can increase the yield and potency if you use them during the flowering stage. We'll see. And, as far as the pH goes, I just read that adding white vinegar will lower the pH. They said you should not use Wine vinegar or cider vinegar as they may contain undesired organisms in them. Vinegar did the trick. pH has gone from 7.4 to 6.1, mighty sweet

Its red that you want for budding, blue is for veg

Vertise: I would think you would place the leds as close as possible because they don't put off much heat at all.

good luck on your grow.

From what I've seen and read, the LED's can be placed 6' to 7' above the plants. The light doesn't decrease like MH or HPS lights do. I even tried it myself byt placing one panel about 1' from the wall, the light looks just as intense from 6' away as it does from 1' away, it just covers a larger area. Thanks for the advice on the blue lights, the blue to red ratio of my lights is about 64 to 161/panel. That much red light should be good for flowering

i think its way too far from the plants.... but what do i know...


i figure as long as i aint burning my plants, i put them close as possible

i agree led is measured in nanometers. the lights should probably be around a foot or less for optimal lighting

I was just looking at some very nice LED grows in high times and they had the lights about 8"-12" from the plants so about a foot.

did you see the high times ufo led grow, way to expensive but pretty cool

I did some more reading from the manufacturer of my lights and you guys are right. The lights should be between 12" and 18" from the plants. Since I've mounted this set of lights to the ceiling, lol, I'll have to figure out how to use the other set of lights that i have, they're shaped like regular sized light bulbs. I'll probably figure out some kind of track lighting system for them so I can lower and raise them as I need.

So, I lowered the lights today, lol. they're exactly 13" above the pots. Was a pain in the ass, but I got it done, hahaaa.

dude i wish i had your fuckin grow room its sweet! come stop by sometime..

hahaaaa, you anywhere near south western Ontario? lmao! so anyway, those free Kahuna seeds I have suck ass. they're 0 for 5 so far. they've been in the rockwool for 6 days now and aren't lookin to good, couple are brown and shitty lookin, lol. I'm giving the other two Juicy Fruits a few more days b4 I move them. The Texada Timewarp seeds look to be pretty healthy, sprouting leaves after 2 days. I think since this is an experimental run, I'm gonna save some seeds in case it blows. I'll need something to start the next run if I dont get a mommy. We'll see how it goes now that the lights are at the proper level, hehe

rofl i meant my journal lmfao

Haha, me strong like bull, smart like tree! hahaa

Well, there's a noticeable improvement this morning after lowering the lights yesterday. The two girls that I have put in the system are quite a bit mote perky today, showing some growth on the wee leaves. The other seeds I have in the rockwool took right off last night. Looks like things might be progressing the way I had hoped, haha ( Lights are on 24/7, 13" above the girls) Grabbed a floating thermometer today, a 12" bubblestone and some pH down. Reservior temp. is 68F, Res is really bubbly now, lol. pH should be cool real soon. (was 7.4, yikes) OK, got the pH down to 6.01. Sweetness, lol

Ok, here's a quick update on how the girls are doing after 1 week. Lookin mighty fine, I do believe. Gonna flush out the res. this weekend and start with a new nutrient solution. I'll be using DNF A&B series grow formula.

Hey Thunderchunky - What's up?
Always glad to watch another LED show! Good luck! I have some future plans for using LED's in the veg stage and maintaining "Moms". We'll keep our eyes open!

Soo.. did you buy that tank heater? You don't need it. A little lower than 68 would be better, holds more oxygen. VV

no, i didn't bother buying a tank heater VV, the temp stays right about ideal anyways. I will need to pick up a humidifier though, the RH in my room is only 35%. I need to get it up to 45-55% i believe.

Well, flushed out the reservoir today. went and got me some Culligan spring water to refill the res. DUMB idea there, hahaaaaa! pH is at 3.9, after adding the nutes. Was 3.4 b4 adding them. I think I'll just stick to tap water from now on, hehe. Now I have to make a trip to the hydro shop again to buy some pH Up, lmfao. I'm starting to feel like an obsessed, mad scientist, lol. well, maybe some wicked hash through the bong will help me put this onto perspective, hahaaaa.
