Does Reservoir air stones provide enough oxygen for continuous top drip feeding CoCo

[jake1983]

Hello,

I have searched and seen many feed schedules, and I am aware the most common feeding schedule for a medium such as CoCo (mine specifically is 75% CoCo & 25% perlite) that retains moisture well is roughly around a 4-6hr off / 15 min on schedule, but I am curious if the Reservoir aeration provided by my 2 pumps and 2x 14" stones in a 50 gal Reservoir is enough oxygen to do a 15min on / 15 min off feeding schedule.

I am new so go easy on me Thanks in advance for any help, suggestions, or tips you can provide.

Anyone have any thoughts on this? Do air stones provide enough o2 for the roots?

In short no.

When using coco one should not consider airation of nutrient solution as a substitute for allowing the coco medium to dry properly between feeds.

Thanks guys, thats what I wanted to know. Quick follow up question.... when I was watering by hand in Coco I only fed every other day as all thw suggestions I had read to let the medium dry out, but for top drip I see most people do 15 mins on and 4hrs off on timers. I tried that and my CoCo / perlite mix is now always moist. Is this okay? Just started that rotation and its okay after 2 days, but I want to verify this is correct and im not causing damage.

What are your guys thoughts?

Thanks!

You're positively begging, on your knees in tears, for a good old fashioned wholesome case of pythium.
