[Support request] Flexitank (Pro) above pot level or not? To Parent Forum April 10, 2023 at 1:30 pm #1190 BlobbyParticipant Dear Josh, I’ve bought a 100l Flexitank Pro and would like to use it for my vegetables this season but I haven’t found an answer to my question yet: Is it neccessary to place the Flexitank ~15-20cm above the pot level (as you have to with the stock 47l Tank) or does it work if it’s standing on the ground like the pots? Thank you in advance! April 10, 2023 at 1:32 pm #1195 JoshKeymaster Hi There….. This size reservoir will be fine to place directly on the ground, just ensure the ground is level, check with a spirit level and that you re-fill the reservoir when there is a third of the solution left.
