Wile e Peyote
Who, what, why and where
I stuck my hand in there before red on full blast and it didn't feel that bad with the homemade valve I can slow it down by around half speed and may be crank it up when the roots are fully establishedYou maybe right there Wile,when i was researching bubble buckets a lot of growers said you needed at least a 30l/min pump to get big plants.If i remember right.
With 60l/min your roots would nearly be living in air,if they can stand the turbulence.
