ן wanna know a about the method of giving ice wat...

Hey there Walg, the ice/cold water thing is to sort of shock of the root zone with cold temperatures which theoretically makes trichomes shiver out more and promotes the creation of terpenes. The sad truth is though even for a short 3 month grow, there is not enough time for new trichomes to get ripe with THC , but for sure the ice thing works for better taste and nice bud in general. Either water with the coldest water you can find the last week of flower before the chop, or get fat blocks of ice and let them melt through like @wheedtobeus does. You do this seperate from your dark period though. Hope this helps ! 🚀
