well for starters you must use a plastic that will not be eaten by the Ozone. And for some reason comercial ozone gen use a mesh , of stainless steel.
If the ozone is not direct venting to the outside air it will distroy , plastics, wiring,rubber that comes in contact with the venting.
With out a timer with the gen you will way over shoot normal ozone levels.
The reason you do not see plans for ozone gen is the safety factor.
For some reason large growers use the comercial types for safety and the cops. Any nark can smell the effects of ozone , in fact its one of the things they look for.
I have built a few ozone gen and you must use a plastic that can withstand the direct contact of high ozone. That white bucket is not a ozone safe box/bucket.
Please think safety or you can kill someone. Direct hand to hand conducts electricy through the heart , and screws up the heart even if you young.
THINK SAFETY FIRST , THERE IS NO AMOUT OF POT WORTH A LIFE
