Hello, this is my first DWC grow, but I have quite a few soil grows under my belt. I haven't started yet, Im trying to get preparation done first :thumbsup:

So I am doing a 15 basket DWC grow. I am using eight 18gal totes made by steralite. I have 12" diameter baskets, 2 per tote, which means one tote will have one lady all by itself. The air pump im using is a 385 watt pond aerator, 300L per minute, 0.05MPa, and it comes with a 20 outlet adapter. Here's my first question: If I plan on running eight 5" air discs, one per tote, will I need to do something with the other outlets on the air pump? Will I need to buy an adapter to fit just 8? Also, will a 5" disc from this pump be enough for one 18gal tote? Something else I'm unsure about is air pump power quality. If it's possible to run 8 legs off a 20 outlet adapter, would running additional legs to the same tote increase the amount of air pumped into the tote? Or By adding another leg, (#9), to say one tote, will it just divide the power by that fraction? Hope that question made sense..

The other thing I really wanted to ask about is nutrient solution in the reservoir. Starting out, and further along in the grow. So I have foxfarms hydro nutrients. Tigerbloom, bigbloom, and Growbig. So in the beginning, I wont be using tigerbloom as it says not to. But with bigbloom, it calls for 2tsp > gal. And with growbig, it calls for 1tsp > gal. Here's my question: When making up the reservoir, do you add the BB and GB doses per gal, or individually per gal? So should every gallon of water in the tote have a ratio of 1tsp GB and 2tsp BB? I haven't tested how much water I will need to get about 2 inches of a basket underwater, but lets say it's 10gal. The only other way I could think of mixing the nutes, is say 5gal treated with BB, and the other 5gal treated with GB. Also, do nutrients go bad after so long? I've had the fox farms trio pack for over a year. I placed half the concentrations in jugs, then kept the other halfs in their original containers. Can I use these for the grow? I would imagine air has gotten to these for a while now...

So I do plan on using hydrotron and rapid rooter plugs. I've read that you don't put the newly sprouts into the dwc system right away, but actually to grow them a little before? If I plan on transplanting them into there baskets, how big should they be when I do so? I realize these are big baskets, and I didnt know what size I needed when I bought em, but I know I can just veg longer to make up for it. Also, I'm using two 400 watt MH/HPS batwings as my light setup. Im thinking I may need one more...

Thanks for reading, sorry for the long post but I figured I'd get it all out there.
