LST hydroponic flushing



I would like to start using hydroponics for growing. can i use LST for autoflower? Also how do i flush the nutrients when its getting close to harvest time? thank you lisa


LST is about all that is recommended for autos. With experience you can be a bit more aggressive.

I’m not a hydro guy but can answer: the plant is fed neutral water of correct PH for a period before harvest to flush all nutrients from the plant. It’s pretty easy. There are some additives used in cleaning the lines etc as well.


thank you for your help i greatly appreciate it.
