I'm very new to the size of this set-up, and even newer to hydro so I have some questions along the way
anyway here's a little info on the setup...
room is 10x20 with 10x16 being utilized right now, plan on adding an additional 2k on top of the 8k right now and filling out the whole room.
Running 40 plants with two reservoirs using an ebb and flow system.
Have a 3 ton ac to cool the place (gets hot inside the warehouse during summer) and 1 12" fan on each row of four lights, and one 12" venting the room (although the room is not sealed atm so they all three vent)
Have a sentinel controller and 12 burner, which will be turned on during flowering. The room will be sealed at this point as well.
Temps stay in check around 75 degrees, lights are on 24/7 atm and will be switched to 12/12 in the next day or two
Here are the pics of the yellowing I was talking about..
and a different plant
STATS from today from the res that hold these plants..
Temp 60 (colder than usual..assuming because the lights were out for 12 hours for the first time)
pH 6.5 .. a little high but I brought it down to 6.2 with some natural down..
EDIT: The drain pumps (in the controller bucket) failed and the buckets were filled for several hours, and they all appeared to be over watered. Any fix for this? They seem to be perking up now..
