Do you up the light power when the pistils show up. Can go up to 900 or so umols but dont want to burn anything.
What’s your medium if it’s coco coir you can easily get into the 1300s if you keep the medium moist otherwise roughly1100 should be your limit
Soil how big for the pistils to be before full light
For clarification, that’s not the way it works
Ok about 24 days in for my autos they are showing signs of flower nice big plants. Is now the time to lower the light from 30" to 24" . thanks for the help.
