    certain color leds on during dark cycle?

    I dont think this is considered ground breaking since it has been discussed years ago and im sure someone has tested it. I'm looking for results, if I cant find them it would be cheap and easy experiment to perform so I may give it a go. Although i have to agree with your previous post as i...

    certain color leds on during dark cycle?

    Been there, read that. On that site there is no conclusion to his study. Just a hypothesis I am more intrigued by the scientific side of things and experimenting. I am in no way trying to replicate nature, more in a sense trying to understand how the plant functions and attempt to manipulate...

    certain color leds on during dark cycle?

    Has anyone experimented with certain colors of leds (yellow, amber, orange, blue) on during the lights off portion of flowering? I have read that 660nm and 730nm are what primarily effects phototropism and the conversion of pr/pfr. So I guess in my head it leaves the curiosity of what would...

    Experienced LED Pro's Help with Red Spectrum Ratios

    Wow great info everyone! I am not exactly convinced just yet on the full range leds yet either, but i see and understand both sides of the argument and I cant decide if one is truly superior to the other. My last panel did just as Eraserhead described. It stunted growth and i believe it may...

    Experienced LED Pro's Help with Red Spectrum Ratios

    I have built a couple panels and have had moderate success. I'm curious as to what others who have actual experience with building their own panels prefer for color ratios. Primarily the ratio of 660nm to 630nm? For both vegetative growth and flowering.

As I thought before posting this ,to me(rookie grower), I would say it looks like they are potassium and or magnesium deficient. My main question is if this is caused due to the new home and move from hydro to soil? Or if...

    150w hps cool tube cfm question

    I dont want the setup to be really loud. Im sure a 150w hps doesnt throw off to much heat to require that size of a fan. I have read threads of people venting an entire grow room threw a cool tube with a 250w hps running a single 4inch 100cfm pc fan. I already have the 80mm 40cfm fans, i just...
