Wow you got your own compost pile i bet thats some good stuff.I just think it has that male look.yea wait we will see..dude, when we grew at that farm they were 10ft in the first 3 months....no fkn lie, we grew some monster n lights and afghani...fkn fan leaves were over 2 ft....im not to worried about the soil,the farm closed about 20 yrs ago and all the topsoil was bulldozed into mounds back behind the home depot they put there...oh, why ya think the taller one is a male? the taller ones sprouted two weeks before the durga....or does it just have that male look? its been in the back of my mind but figured id just wait to find out....
3x3 = 9sqft divided into 600 is wpsqft 4x4 =16 sqft divided into 600 is wpsqft i dont have a calculator handy,lol But i no 3x4 is 12sqft into 600 is 50wpsqft.When they say it covers a 6x6 you will have alot of places not getting the good light hence moving plants around to achieve even growth.I think you will be fine with the 4x4 and get good tight buds,thats just the way i was taught and works good for me 30 wpsqft is the borderline tho as far to achieve good solid buds.Also with you being able to get your light that close you will get great tight buds opposed to loose when you go to the 12/12 photoperiod.I would stay around 2 ft till flower then try to get as close without burning em like the 18inches,THIS will give you some Great buds.Lumens decrease drastically with distance from canopy.The closer the light the denser the buds will be youll see when you get to flower how the buds at the bottom will be more stringy and less dense its just something your gonna have to find out what works best for your grow and likes..the grow space is 4x4, i lowerred the taller plants down a little....they are now about 2 ft from the light...i thought the print for a 600 would be 6x6...doesnt that give u 100 wtts p sq ft or am i not using all of the equation
