On the drip system I think I would go rockwool cubes with hydroton pebbles just because I havent use the rockwoll filler yet so Im not sure what retention it might have and I am familiar with hydroton clay pebbels...The square pots I use are I believe 6 inch pots thats across side to side. Yeah this was one of 2 ways I learned from the older guys who I got my begginngs from.They either laid rockwool mats on the table in rows then cut a square out and fit the 4x4 cube into it and then filled the entire table with hydroton about 3 inches deep or used the pots. The pots are cheaper and if your gonna stay 2-3 feet finish work great now if you have room like the others they grew thier plants to 5 feet in tables but they had large pvc grids and a warehouse so they went bigger..In my flood tables it varies I like 4 waterings a day.This 3x3 table holds 12 plants well thats about it for this style without a mini sog and lollipopping. I set my timer to water every 6 hours for 10 minutes and then it takes 4 minutes or so to drain.Now for the ebb and flow buckets I dont have any of those but if you mean my aero type stuff I run the pumps 24 hours a day and will be doing a journel on the next full aero setup I do which will be 28-32 site setup...sloe glad I had something that helped ya out lol..The tents Im working on figuring what I can do to make these availiable and at waht cost.The basic tent costs be $45 right now but Im trying to get bulk prices.Then the frame and mods.I wanna keep the cost in the $100-120 range if I can...The unit holds my old ass heavy steal half cylinder reflector pretty good but I already had ideas to make it even better but this was my proto type to see what it can do and what it needs.The pvc flexs some but not bad at all.I think I can maybe go with a solid type of material for the ciieling to offer an even stronger frame.These have 2 spots setup for fans one for in and one for out.Very easy to setup a co2 line in the cieling over the plants.I will perfect this unit hopefully in next month or 2...I also have to get ready for my challeneg and build my own version of the BCNL Bloombox.I was told that the $grand they charge is rock bottom for thier units and cant be done for less.Soooo me being me I said I can do it better for under $700 so thats coming when it warms up.I will do it better and Im gonna shoot for under $500 if I can with lights we'll see...Ive done the basic versions of most grow methods.I ve done soil,aero,flood and drain,drips,dwc,bubblers and Im tinkering on a fogger setup but I am learning everyday and I havent done like a wall grow or a stadium seat dirt grow yet.I will though lol
