Flushing question!!

when i flush my plants at the end of my harvest do i need to pour out the water from the trays under the pots or should i let the plants soak back up that water?

I wouldn't - the idea is you're flushing all the nutes out of the soil so the trays could have some nutes in them. Just take the trays away ~

You should dump the water out, they shouldent sit in water because they need time to dry out after you flush them so you dont over water. Good luck man

You would need the trays tho because when you flush you want to water untill there is run off....correct??
