you are supposed to use an equal amount of water as pot size.if you are using 3 gal. pot,then use 3 gal. water.i myself do not flush.i just feed water only for the last 1-2 weeks.just use regular water for the all,except the last gal. of water.ph the last gal.hope this helps
I start giving distilled water only at two weeks to harvest, then flush at one week. IMO, the flush allows the bud to burn all the way to a clean, fine white ash.............
i just water with str8 distilled water for the last 2 weeks,my last watering,i water until the water flows out the bottom of the pot for a couple minutes.if your using miracle grow as a nute,id recommend doing a couple good last flushes.
IF your going to flush you should use 3 times the ammount of water to gallons of potter ( 5 gal potter =15 gal of water) and when it comes to water to use i only air mine out i let it stand in a bucket overnight so the chlorine can evap. Distilled is fine but with out a system to make it, it can cost
Thanks brothers and sisters I use Canna prods I have noticed before last couple weeks flush buds get like 1/3rd bigger I think I had bag seed so all seem diff which is a hassle .......
