Grow Mediums Do you put layer of perlite or hydroton in autopots watering system pot?

[Olderfart]

After reading the complete autopot review thread by @Olderfart , I think I may just scrap the airdomes/stones and hydroton at the base all together.

I already have the Mother Earth 70/30 coco perlite mix, and may just mix a little hydroton into that to air it up some more since I have some on hand.

What Im not clear on is how to monitor/adjust EC and pH other than to just pH balance the reservoir. Also, my medium is supposed to be buffered, but not sure how to test that yet....runoff pH and EC probably.

There is not much you can do to test the buffering. There is no harm in buffering it again if you don't trust it though. Just soak it overnight in a calmag mix 2x the recommended strength, rinse it, and you are ready to go. OTOH, if the manufacturer says it is buffered, it likely is. You might see if you can find a grow report from someone using that product.

Good luck with it.

After speaking with @Olderfart i mixed promix with hydroton in my autopot dunno the ratio but 2:1 promix to hydroton or something like that, looks like a good mix. decided not to use air stones and keep this simple. hope this helps.
