The middle and right beds look great at day 22F. They have nice healthy growth, and are starting to stack some buds. At different times I’ve gotten whifs of BBQ sauce, paint thinner, and dank weed in the lung room (through the carbon filter). There will be no shortage of hash this round.
The left bed is still struggling, however. I recently fixed a heat and PPFD level issue. That seemed to slow the progress, but not really solve it. I have also considered nutrition, airflow, and root zone temperature.
As far as nutrition, all three beds have been fed the same, and were amended at the beginning of the cycle based on a soil test. I’ve also been giving them soy aminos, humic acids, microbes, trace minerals, and some FPJ/FFJ every 7-10 days. They are due for their next feed tomorrow.
As far as airflow, I got a second fan for the opposite corner and another controller for both fans. I disconnected the blumats on right bed and pulled it out. I got the second fan mounted in the opposite corner, and hooked both fans up to the second controller. I setup the controller to cycle 45 min on, 15 min off.
I did all this at lights out with a red headlamp. I will need to bleed the blumats and make sure they didn’t get messed up with me moving the beds around when the lights come on.
As far as root zone temperatures, the wall next to the left bed is an exterior wall in the basement. So I grabbed my IR thermometer. The right bed/soil surface was about 72°F, middle bed was 70°F, left bed was 65°F. That back wall was 58°F. That was lights out temps, so ambient was about 68-70°F. I’ll check lights on temps tomorrow morning.
