Ive been on a quest to get plants like I had in hydroton! This last year i spent with promix and havent come close ...I once did a constant drip with hydroton and had the healthiest plant ive ever had,the thing had bark
.Is your idea a constant drip or timed drip? I like it tell me more!
However The bottom rack would be hard to fit anything under in this setup.
I have been playing with the hempy cup idea for all my veg needs this month and am quite impressed so far.This made me wonder if it would be possible in the rack reality..I have a drain hole in each tub so unless i could do it through that fitting i would need new tubs....Not sure if drip or hempy would require more water,but I do have a 70,and 2x100 gal res i could use...My ro is just very slow lol
This room could be bannanas in hydroton!!
*There are 2 wall fans and 3 floor fans and 2 x 8"in/out
First off!!! Low 80's arent bad, butI highly recomend dropping things to 74-78f your last week!! Your terpen profile should be much more established
On to your badass setup,
I would just run a constant flow.
How far off the ground is the bottom of your tray?
You could use a 18 gallon tub with a float valve in it below the drain on your bottom row of trays. Run a line from the float valve to a big 30gallon tub with air stones above it.. As the water is pumped from the small tub below to your system, the float valve will keep the water level below your bottom trays creating good circulatiin. When your olants drink enough that the water level goes down in your control bucket, you top off will fill it back up until the float valve is back to the proper level. You would only need a tiny pump, so getting too much water in your system from your big res. up top shouldnt be a problem.
Could actually make for a really simple grow! And most of your water is always in your reservoirs making ph changes quick and painless!!
