Just a question. I use the dli chart for “autoflower” as my guidelines. I haven’t seen the chart “cannabis” before. If memory serves me correct, 12 hours of light at approximately 50 dli is roughly requiring 900-1100 ppfd. So there saying to start flowering at 500 ppfd? Then ramp it up weekly. Anyone following these guidelines? How’s it working?

My photo plants seem to respond very well to the intensity changes. Keep in mind that there’s a number with CO2 and one for without. The dli drop at week 6 was a game changer in that my plants flowered faster and seemed less stressed at the turn.

CFM – cubic feet per minute of air exchange. The figures represented are for a space somewhere between a 4×4 tent and a 3×3. Everything that you add increases the amount of cfm that you need (bigger fan).
