Dude this shit just inspired me to do a 20 plant solo cup filled flood table, the exact same setup you have a DIY ebb and flow , Is this your first time using the cups? I was wondering about yield, or any issues you've had with using smaller pots in your setup
I have been using this same table for over two years.
I have used smaller volume cups (10 oz) before and I can tell you that the size of the cup is not critical really.
The plants get everything they need regardless of being constrained (in this comp) by the roots staying IN the cup.
Outside of this comp I just let the roots go crazy outside of the containers and have actually had, at harvest, a mat of roots at least 2.5 inches thick filling the entire tub. The container really only acts as an anchor for the plant.
I had three plants of some wicked genetics (Colorado genetics) produce over three pounds of product last fall. After drying and curing I had 1.75 pounds of bud and almost 2 pounds of frosty trim that made some bad ass hash that I still smoke almost a year later.
I use A51 led lights and GenHydro 3 part nutes. Timer on lights is dependent on cycle but the table gets flooded every 2-3 hours including once before lights on and once after lights off.
Technique is key, pay attention to the plants and give them what they want as far as timers go.
BTW, I do not PPM or PH, never have.
I use the table on the back of the nute bottle and mix my shit 5 gallons at a time.
I only clean the res after harvest and I do not flush but I do scale back the nutes to half strength a couple of weeks before I harvest.
