is 3lbs off a 4x8 table with 2 1000watters over it using ebb and flow sound like an unreasonable expectation?
i am planning 3 of these tables perpetual 3 week rotations with 2 1000watters over each table
3lbs is quite obtainable. I average 2 to 2.5 lbs on a 3x8 flood and drain table in my sog grow-op and I am in the process of upgrading my 2 tables to 4x8's , I got one finished and loaded up with 104 clones that went straight into flower from the aero clones. Hoping to do 3 to 3.5 on the larger tables. But a lot variables need to be considered, like your # of plants, strain (I like ak's best )humidity,temps,CO2,ect,ect
I have been running flood and drain SOG tables for over 2 years but did not achieve steady results untill a year ago. The first year was a learning experiance even though I thought I knew what I was doing lol. Trying different strains,nutes, adding CO2, timer and ventalation problems, a continuing battle with spider mites. It takes a lot to get your room dialed in...so I wish you luck my friend and I will be glad to share my limited experiance in any way I can. Here is a cpl pics of my flood tables in action.
