Grapefruit DWC - my first indoor auto

Make sure the white isnt PM, sometimes when humidity is a little high in the tent and the water under the plants can start it early on. If it happens to be PM 40% homoginized milk and 60% water and give her a spray. You also should try to keep your humidity down around 40% as when growing in water your humidity around your plant is actually quite a bit higher than what the tent says it is. Cheers friend

To be safe in mid to late flower keep it down 40 % and under if possible. Not much risk of bud rot then. You could Mcgyver a dehumidifier to suck from the tent while sitting outside the tent. Very effective. Cheers

Hi mate, imo as I see it you are at least 2 to 4 weeks from harvesting. May be the colour of thc seems right but the buds are not fully developed. If you grow in a dwc system and not soil you can flush 3 days before harvest. There are products for this. Untill you see the pistils turn orange about 70% dont check the thc with microscope. Usually when you think you are ready you still got a couple of weeks. From the pics I ve seen you are 2-3 weeks far from ready. No matter what the seedbank says to get the max out of an auto the grow cycle should be at least 12 weeks from seed to harvest. Hope was helpfull.
