Turns out I have an auto in the group (tsk tsk) lol. No plans to switch lights for another 2 weeks
Upped the air exchange because humidity was becoming a booger. Now parameters-Temp, RH, CO2 all well.
Have roots reaching the reservoir so root system is doing well lol. Not blocking return, fortunately. PH has crept up to 6.1-6.2 so keeping an eye on the new inline pH Perfect unit. Little disappointed with the amount of non dissolved granular food material in reservoir-may be an argument for liquid food products. Added cal mag because one plant indicating a mild deficiency so I believe it was caught quickly enough - all ladies bushy, green and happy.
I would love to have a growspace like this. Your plants are looking super happy and I wish you luck that the autos will do well under 12/12. But I guess they will anyways.👊
