Buds are supposed to fatten up a bit during those 48 hours but I see no clear proof that this actually does anything. What about lowering temps and humidity during the last week? I have seen it done with photoperiod strains and this make more trichomes but I am not sure if this works for autos.
I see many others who done 24/0 and it was a very good grow.
Will go for Bluelab PH Pen and to maintain it Bluelab Probe Care Kit - pH to test my runoff.
Decided to go with 200mm (8") RVK200 A1 Extractor Fan - 750m3/hour for outtake with Carbon Filter CF800 (matches 8 inch RVK200-A1) and for intake 150mm (6") RVK150 L1 Extractor Fan - 660m3/hour to create slight negative pressure to prevent smell escaping.
