have a few questions about a dwc, so here they are:
#1 - regarding the size of the tub, what is recommended? Is there a big difference advantage to using 14 gal rubbermaid tubs vs the 10 gal ones?
#2 - when you cut the holes in the top of the tub, is the idea to make the hole just slightly smaller than the TOP (the open end) of the pot, so that the whole pot except the lip at the top is inside the bucket? how much of the pots should be submerged in the water? (ie, should the water just barely touch the bottom of the pots, or go 2 inches up the bottom of the pots, or what?)
#3 - using 10 or 14 gal rubbermaid tubs, with 2 plants per tub, how much yield can be expected per plant? ballpark figure?
#3b - how many of these 2-plant-each tubs can 1 400w HPS light reasonably handle? what about a 600w?
#4 - what growing medium do you guys recommend for in the net pots? have heard so many conflicting stories. hydroton seems popular but a lot of people report issues with it. suggestions?
#5 - why do the airstones (well the air pumps) need to be on timers? have heard that 1 minute on / 5 minutes off is the general standard for this. why not just leave them on constantly?
#6 - nutes - can anyone please recommend good nutes for this system, like really specific... have done a ton of reading but everything is fairly vague ie they suggest what NPK ratios to look for but not exactly what product to buy and how much to use. need firm guidance.
thanks a lot, don't have a lot of posts yet but have been reading up for a long time here.
