Questions
Does the FlexiPot system need electricity?
No. It runs on gravity, so there are no pumps, timers or running costs.
What growing media can I use?
The FlexiPot system works with soil, coco or hydroponic substrates.
Where should the tank go?
Above the height of the pots, so the solution flows down to the valves.
