yes I am blowing colder air in the tubes as we speak(read somwhere that it could help), the incomming air is 13-14°c, and my observations tell me it has heated to 18-20°c where the plants are or mabey the blower is not doing much, the system is 3.5 m long and i am only using the first 1,5m(at this time), the air is comming in at the other end. should I stop this immediately??? and focus on lowering res temp???
The tubes are pp or pvc something like that, made of white plastic materials.
I did wrap them in black and white plastic from start so that there would not be any light penetrating the roots, there may be some leakage around the plants but not much.
Res is about 19-21°c now, and the water comming out of the tubes is allmost the same, mabey 22°c if that much..
And the depth of the water is around 1cm with a good and constant flow, at least 1L per minute. should there be more water and closer to the plants?
And unfortunately I can not post any pictures, sorry.
thanks again, please keep the ideas comming... I have learned a bunch on this site..
