Stupid questions are far better than stupid mistakes, Grasshopper. :thumbsup:

It aerates the water - mixes tiny bubbles of air in with the water.

The roots need air to survive, so having a nice airy mixture of nutes makes the plants grow better.

It's essential hydro, recommended for anything else.

PharmaCan Reviewed by PharmaCan on . Quick Question on Airstones? Hey, I was wondering how important it is to have a good airstone with fine bubbles? Because I am modifying my system and I need to add 8 new airstones... and I would rather not spent $50 per airstone for the ones that produce fine micron bubbles. What is an acceptable micron level for growing plants hydroponically? If anyone has found good cheap ($20) airstones that work I would be forever grateful :stoned: Thank you all for your time.
