Question for you mate. If I run the exhaust during the day, it brings RH down to about 40% which is at the low end for small plants. However it means a steady supply of cool filtered air being pulled from outside through the air conditioning system. Would you favour the steady supply of fresh o2 and CO2 over the little bit of humidity? As long as we stay in a good VPD band?
Started doing a light rhizo foliar spray just to make up for missed nutes in that first week. They love it. Instant colour change and they just look healthy. Have put some in the tank so their next 40 litres they will get a nice hit of rhizo, hopefully help them fill the pots a bit. Hope so, stuff is not cheap.
