You can top water occasionally, or even turn off the res for a couple days. With soil the pots will stay moist 4 days at least.
Okay guys so today I drain the last little bit out of the reservoir and refilled it with Fresh Feed pH 5.9 for up drift I'm trying to stay right at 6. Also since you're not supposed to top feed the plants once you turn the autopot system one I was wondering how I'm going to run recharge and Mammoth P once a week so what I've come up with is mix up them two things and then take out the aqua valves and just fill up the trays with Mammoth p and recharge and let them soak that up and then turn the system back on. If anybody has any suggestions on a better way to do this please let me know. Also with the mammoth p on the back of the label it says to use within 2 days so that is why I don't think I'm going to put it in that Reservoir right now until they start drinking more but once that Reservoir starts getting Drank in 2 to 3 days I will add the mammoth p in the reservoir. And I will also take the measurement today and then record how much they drink in 24 hours for you Bailey
