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.
