I’m starting my 1st photoperiod a Humboldt triploid Donutz in a 10 gallon ac infinity auto pot in happy frog potting soil. I’m finding all kinds of different advise on when, what and how much to feed. I’m using GH nutes btw. Any solid advise would be greatly appreciated. Thanks

With a 10 gallon pot I would guestimate 6ish weeks easy and could be longer. Checking the run off around week 4 of veg would be a more accurate method…start a nutrient routine once that run off is 800 or less

Follow the above given advice here. That was the simplest and possibly the best way to explain it.

yeah I did an initial soaking and read the runoff as 7.5PH and 1300ppm. so, where do i start feeding 800 or less like you said?

Happy frog will feed your plant for 4-6 weeks. I agree with @OGIncognito start checking ppms around 4 weeks. Or sooner to get used to checking it.
Im wondering why your runoff ph is so high. What’s the ph of your water going in.

Maybe I am/or did misread you are in AC infinity Autopots, way I understand you only top feed until roots hit the bottom of pot then start feeding from res and adjust ppm and ph there and plants will take what they need,? Did I read first post wrong?

I think what happened was i PH’d the RO water only once and I think the buffers let it bounce back a little high because I usually have to bump my initial adjustment at least once, but this time I went directly to adding the water to my bucket. sorry for that. On my hydro I maintain a solid 6.0 PH but I went with 6.5 for the dirt. I thought I had read that that was the goto number for soil.

No you are correct. Definitely bottom feeders. My only issue with this is that they tell you you will know when the roots are down far enough when the edge of you girls reach the edge of the pot, my problem with that is that the xl pots are super wide (16.5" I believe) but kept short (12") so does that rule of thumb still hold for a short fat pot? The pots only wick water up a third of the way, but that still means the roots only have to travel 8" to hit water. I like the idea of letting the top dry out semi-permanently to keep the critters under control.

Also, it just occurred to me I need to do a calibration on my PH stick, I haven’t done that yet. thanks for the heads up!

I am going to use Autopots on next grow only 3 gallon pots indoors, going to do 9 gallon on porch for tomatoes and peppers and 2 weed plants 6 total, as far letting plants reach outside of pot you may be on to something that’s big, My way of thinking is once roots grow and take hold is when you then see plant take off and grow fast, busy/taller, thicker is when you can safely start the bottom feed system, I guess I shall see before to long, once weather is grow worthy here, will be tagging along to see how you go and will share what I figure out luck to you
