How can i aerate my soil?

I didn't manage to put perlite in, which i regret. I was wondering if there was a good way to get some oxygen down into the soil?

Any suggestions?

I wouldn't recommend any sort of poking or jabbing sharp objects into the roots. If you are growing a potted plant, you can lightly bend the sides in around the pot when the soil is mostly dry. Also the watering cycle will be key, water-day A, wait day B, wait day C. Oxygen will naturally creep into the soil doing this ( unless you have the soil packed in and there is no space, but that requires a huge absence of common sense ) you probably just watered it and it started packing down. So just make sure you aren't watering everyday this will drown the roots, and try applying quick but gentle pressure around the lining of the pot if aeration is a real concern. Good luck, and Jah Bless

I know this is a super old thread, but while I was looking information for an idea up, I stumbled across this and figured I could offer some advice for future inquirers.

I bought a 20-gal air pump, some tubing, and an air stone. Place one end in the water reservoir, plug it in, leave it on, and your water will always be as saturated as it possibly can. If you dont want to run the pump all the time for one reason or another (usually noise) then simply aerate your water with the pump an hour before you feed.

I also use the rising bubbles to help me mix the nutes. I use a 5 gallon water bottle for storage of my RO water and move it to a 2.5 gal arrowhead type water bottle that I cut a square out of the top to do my mixing in. Simply place the bubble stone in there and have my ph meter attached to the side. I can monitor my ph as I add my adjuster.
