I will keep them close then.^ just keep them as close as possible to the top of the plants without burning them.
I swear by it.. its the best damn thing on the market... I hated the price, but i will never grow without it nowI'll look into it. 60 percent more light would be awesome!
All of the above... it really does act as though the light your feeding it doubles.. the growth rate almost doubled the very first time i tried it (been doing this for years).. The yields increased as well..How has it affected your grow? More yield, thc, both?
