@Pete420growdiaries,
To be fair I have had big problems and I have had to cut the lot and start again after them getting pollinated and they full of seeds and I'm thinking of going back to my 600w hps and I'm going to start again fresh with 12 autos and then pop seeds every 8 weeks to keep me in supply but I have lost alot of money with things going wrong im gutted but we learn has we go along very nearly packed in growing but I will Try again and going back to basics cos the weed produced from leds was very lite and wispy no dencety at all so I'm really impressed with leds I'm also in uk so I feel that the hps will help me with heating costs being slightly lower has the light will produce heat in tent I have twin fan controller and in and out fans and my heating is temperature controlled so I will have to play around gas I go happy growing
@Growladyeastmidlands, yeah i have heard that your lights(mars) are one of the best, but quite expensive or not?
I lowered my lights but if i lower to much then they grow to the middle, all 4
@Mr420, thanks buddy, i lowered the light a week ago and its better, the stems are bit thicker so we'll see but i wait a little longer for a fan inside the tent till they are strong enough
