hi intoxia,
you will be taking a significant risk.. there should be no need tochange the water in your reservoir so often... water movement like jdogg said is KEY...

add as many air stones as possible...

it is very difficult to overcome root rot in an aeroponic set up once you get it...

have. you considered cloning your plants now... this is what I wuld do...

the roots that a plant grows to absorb nutrients in an aeroponic grow are different than the roots that a plant grows in soil ... meaning.. your plant will struggle when you change the medium and it could very well die...

although the 80% perlite mixture that you suggested sounds possible....

regarding the ph... I agree with zandor... you may want to start with a bit lower ph than a normal soil grow to avoid any chance of ph shock...

have you added hydrogen peroxide to your reservoir?

you prediciment is tough and will be a tremendous learning experience for you...

how old are your plants?

Garden Knowm Reviewed by Garden Knowm on . GK:can I switch from aeroponics to soil during same grow I had a problem where my plants got root rot in my aerojet aeroponic setup(i think because the roots just sat in the water and it was warm, eventhough I changed the water every 3 to four days). My solution: A) elevate the trays on one side to increase drainage B) When the roots grow out of the 4inch net cups tansfer to a 80% perlite/20% peet moss My question is do you think this is a good idea, also if it is what extra precations should I take regarding ph of soil and ph of water.
