One more thing; pulling the old batch and slipping in the new one took an hour, which included dumping and flushing the old nutes and loading up fresh sauce.
That was by myself. It's quicker if I have help. I'm of the opinion that every minute a bloom room is not full of plants IN BLOOM is a minute wasted. Fucking rooms are expensive and they only pay for themselves when they're running. And yes, that includes any veg; find and make a separate veg area for the youngsters. You can size and light the room better and so it's less wasteful.
