Light Leaks Ruin Photoperiods

[justicebzwieg]

Twelve full hours of real darkness are what photoperiod CBD strains need to flower properly, and a tent zipper glow or a status LED on a timer is enough to cause trouble. Symptoms range from a stalled flip to revegging mid flower and, in stressed lines, male flowers. The dark period troubleshooting section on https://calmcbdseeds.com has a simple test using your own eyes after ten minutes inside the closed tent. Autos ignore all of this, which is one fair argument in their favour.
