its really hard to believe those leaves are still so green after a full flower cycle, impressed indeed, if we were smart we would invest in frank and get this shit on the open market,
I know this is because of the size of these beds. No way these things are anywhere near rootbound.
My 1st time using NSPB, I tried to grow trees in 3.4g airpots. Veg in those pot for 2-3 week before flipping to flower. Around week 5 of flower the plants started fading. My next grow, I went up to around 9 or 10 gallons and the girls were happy all the way til chop.
