So I am unable to easily raise the height of my 100L flexitank for my autopots, however it does not seem to be an issue and almost empties my flexitank despite everything being on ground level.
Autopots are still very new to me, busy with my first grow with them still so will continue to monitor it and see how it goes - so far loving the fact that I do not need to water manually and can simply topup the res without any further adjustments.
