Root problems!

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..

i have never heard of such a thing. air blowing on roots? your stunting the roots by air pruning. roots want cool dark wet place, if they wanted air they would grow on top of the ground.

since u said u are using ph perfect sensi ab read this. Need advice from some pro's on brown slime.

then refer to this. DWC Root Slime Cure aka How to Breed Beneficial Microbes

get the non-ph perfect sensi and brew some tea. see if that helps bc it can't hurt.

Good luck!

I think theres a feww issues at hand, your roots are root pruning before they can reach the flowing water.
ways to solve this is to add a drip system to each plant, this will allow your plant to grow roots and reach the water
and at this point you could shut the drip system off. Kepping your water cool is a must! If posable 66f to 70f.
also by adding bennys like teas or like said above greatwhite work well, i like aquashield super simple 20 bucks
for a gallon and works killer.

You are right, When you put it that way it sounds stupid...

And thanks for the links sterner, I am sure I have some brown slime now or algae, just watered the plants with a solution of ATA Clean to see if that helps, I also put some in the res a few days ago because I thought I had slime or algae in the bottom of the tubes then, and it has almost all gone now.

Has anyone had expirience with ATA Clean, it raises the EC level and I dont know how often is safe to use, or how well it works in the long term?

I also think this is spot on... But a drip system may be out, because of low budged.

And the res temp rarely reaches 70f I think.

Going to see if complete light proofing and ATA Clean solution along with more frequent watering will help for a start. spending money on equipment will be next choice.

Thanks...

find a product called pondzyme, i get it at a local nusery, and it is a cheap way to get beneficials and they will eat all the rotten roots.

If a drip system is out of question, then you need to raise the water level to the bottom of your net pots until you have roots submerged!

Tanks a lot, I am sure all this information will help me get healthy plants..

Happy growing.
