The cups have about ½" of perlite in the bottom then topped off with coco that has been in use for 2 years give or take. Used the old coco because I wanted to see what it would do.
Did the perlite at the bottom of the cups because I want to attempt bottom feed.
Ran out of the mega crop finally and am now using jacks for the first time. It sure mixes more thoroughly. Using the ratio, simplified, close to their recommended ratio.
Pre mixed a weak stock solution of each at approximately 10 gallons worth to use at 1:1:1 with ro water.
Have wanted to use the tap but everytime I used it, I managed to mangle the plants severely. Maybe with 3 part can figure it out.
Unplugged the heat mat from the controller, plugged in the little heater to the controller, set it to 85. Placed the temperature probe in the canopy. Did that last night. Probably should have just done that from the start.
