I accidentally flooded all of them for 90mins straight.
Only advantage, they not young plants.
I think theyll get through it but, will it affect outcoming results?
I don't agree with that. If you water to often it will def kill the roots. Shit holds a lot of water. If you have a constant source of water the roots will rot.
I over watered in hydroton. 10 seconds on every 20 minutes was bad. I do 15 seconds on every 2 hours now. I thought it was not possible to over water and it cost me some young plants.
