That is the problem.
It is ancient technology as far as hydroponics goes, it didn't work well back 15 years ago when I first bought one, it is still on a pallet on tbe top shelf in.my where house if anyone wants it.
It works slightly better, nowadays, but nowhere near being able to turn a profit at a commercial level.
It was always and will always be for someone who can sit and monitor each chamber on a daily if not hourly basis.
plenty of other techniques out there that will work better and turn a profit and a good return of investment.
I have been a leader in the Hydroponics industry for over 30 years, and own and manage one of the largest hydroponics wholesale and manufacturing companies in Australia.
So yes I do know what I am talking about.
