I amend for pests. A 4 lb bag of diatomaceous earth to every 30 gallons of soil mix. My mix is 3 parts. Compost, pearlite and peat moss. I move my plants outside on a good day and never had more than a visiting grasshopper. Or a couple of ladybugs from my mellon plants. It works so well I don't know why everyone doesn't do it.Keep your grow closet tightly sealed. You can get bugs even indoors.
Would love to win these 2 items. My best tip is my most controversial tip, during flower do not run full vpd use a modified vpd of 78 to 82F and 75RH up until day 35 of flower then every week lower temp by a few degrees and RH by 5 until you end up work 50rh and 75F the last week of flower.
