Do you flush the bag with water before 1st use?


How many ounces or gallons are you dripping per emitter per day for a full grown plant?


I'm wondering if you could get away from having to use the 4" RW cube to pot on with. Like maybe go from 1' cube seedling right into the bag?

Bags don't have holes when they arrive, propane torch or utility knife are good hole makers. bags need to be slit 3 places in the bottom for drainage.

i no longer measure feed rates, the plants use what they need, usually i set a schedule, and when the bags get light or plants get droopy, i up the feed schedule, when it turns cool and the days shorten i reduce hydro solution usage

No flushing, I just rehydrate with the drippers, by the time the roots are in the bag its been flushed with nutrient.

I use the cubes more as a space management tool, once the seedlings are too large for the 1" cubes, I stick them in the 4" delta blocks in a heated hoop outside, then when its warm enough they go into the coir slabs. the plants do not need the delta blocks at all.
