A question on inputting air to the plant roots

by Dan
(Plainfield, Il. USA)


I have a 30 gallon resevoir with 4 five foot, 4" pvc pipes connected to it. These pipes contain my pots & growing medium, with a pump within the resevoir sending the nutrients to them. That part of the system works, however, I need to get more air to the plant roots. In this situation, is it possible to run a line from an external(to the resevoir) air pump to an 'air stone' on the bottom of resevoir which would send the 'oxygenated' nutrients to the pipes? Or would it be better to run air lines to 'air stones' in each of the pipes themselves?

Thanks for your advice!

Answer from Stella/Simon:
Hi Dan,

What a nice hydro setup! It looks like you are doing a type of NFT (nutrient film technique) system, am I right?

EVERY reservoir needs to be aerated, to cut down on anaerobic bacteria as well as to deliver fresh air to the plant roots. If you haven't done that, then do so. It can be done cheaply by buying a small aquarium pump, airline tubing and an airstone. Then just drop the airstone into the vat to keep it bubbling (try to get a wand, 5" long or longer, or a large disc type stone). Alternatively, you can use a submersible HyDor aerator like that you will find in the "cheap supplies" link to the left.

Aerating the vat should supply all the oxygen you need, as long as your system circulates often. I do think it would be much too hard, and not as helpful, if you tried to put an airstone into your PVC pipes.

Hope I understood your system and your question right. If not, write again and we'll go from there. Good luck...

Hope this helps!

Aeration of roots
by: Charles

I grow my tomatoes in NFT systems made of 4" PVC pipe and two other systems made of 5" square PVC fence posts. I've also grown bell peppers and hot peppers in them. I drilled a small hole in the ends where the nutrient lines enter and ran an air line through the hole with the idea of introducing air to the roots with a small aquarium air pump. The air supply was so pitiful I couldn't tell any difference but I may try a larger pump in the future and make a comparison with that and one with no air and see what happens. It may be worth it if the results are good.
