So I finally got my temps down to 77f by raising my light - I have my plants under a 400w hps, but humidity is at 20%. I also have an oscillating fan on the plants. I know ideal humidity is higher than that, but I've also read some trials that say the lower the humidity, the better because it encourages co2 exchange in the leaves.
Is 20% problematic?
