Audiman... Hey never had one of these visitor messages before. I'll do my best to help you out though. Ok so starting off, you said you have a 4x2 table in a room that it barely fits in haha we can work with that. My reservoirs are 35 gallons... I use nutrients called Aquaflakes that come with a feeding chart. All the conversions should be on the bottle. Tells you how much nutrients to add to how much water. People will tell you to let your water sit out 24 hrs, but I disagree. A weed is a weed and I never let my water sit out and they do just fine. I don't really know what your asking beyond that though man... Try to get your questions down to very specific things so I can better help you. Anyway, good luck and by all means just write me if you need anything.
