You guys would love growing up North. RH in my garden was 16% the other day and with lots on insulation my lights are my heat and cooling is only an in-line fan away.
Flower boxes have a little micro environment going so RH usually sits around 35-40 mark with spikes when I give em a spray.
Cloning is a bitch in cold places though... keeping temps steady in the right range requires an independent chamber with its own controls.
Planning on a small dedicated clone area in the addition I’m building now..

It takes a few days for cannabis leaves to adjust to a new spectrum. If the HID lighting is insufficient, lighting from a side window could possibly be beneficial. Otherwise, I believe you'll get a much better quality/yield by keeping your environment steady.

The revolution is slowly beginning to advance.

Huh i wasnt aware that putting them into a sunny window was gonna result in that. LMAO i think any hid is insufficient compared to that ball of fusion in space.
