I have both of these and thought I'd try a run.
What's the downside of using HP? Any PH rising issues?

What's wrong with Fabric bags and Promix-HP

I use fabric and Promix, never had a problem until I started to amend it with too many other things.

Only reason the ph would rise is if your water has high alkalinity. My tap is at around 120 ppm and I don't have any problems. Fabric pots are sweet, I use plastic because they are easier to move around and transplant from if needed but nothing wrong with fabric aside from watering a bit more often which isn't a bad thing.

yeah, they work fine, but it's hard to transplant in fabric bags, unless you just bury the whole bag and let the roots grow through it into the new container. better to just start in cups or small pots, let them get a decent size, then into the final bag

I like your idea of burying the whole pot. I've just started using fabric pots and putting it mildly, I found transplanting in the traditional way with fabric pots is a pain.

try to do it when they are dry as possible & roll the sides down. massage the sides to help it wiggle out also.

I'm using Perlite hempy pots now and my PH rises from 5.8 to 6.6 in the runoff within a few days. Sure I can flush but then it just rises again in a few days.
I waste a lot of nutes and time flushing and adjusting all the time not to mention all my plants have to be removed from their areas. It's a hassle and I alwasy have sick plants.

Pro mix has a tendency to have fungus gnat larvae in it!

Nothing if u want mid to so so potency levels........the best of the best is NOT GROWN HYDROPONICALY! Cash croppers and veggie farmers in Amsterdam love hydroponics .....top shelf cultivars prefer no till organics......just like they grew in before man touched them!

Promix HP is peat based so I think the pH would tend to drop because peat is acidic. I can verify that promix up has tons of fungus gnats! I tried using straight promix HP and the maxi series of nutes with poor success. I suspect that my pH in the pot got out of control. I did use a proper pH meter when I fed the plants. I'm not that experienced a grower so don't take what I say as absolute truth. Good luck with your grow.

So what did you change to?Promix HP is peat based so I think the pH would tend to drop because peat is acidic. I can verify that promix up has tons of fungus gnats!

I use pro mix Hp.... never had a gnat or bug from it.. also there are fabric pots designed for transplanting.. they have a velcro strip on the pot where you can zip it open to transplant.. i use em and they make transplanting easy... keep doing what you doing.. no downside.. I grow inside fyi.....Peace

you're going to get fungus gnats in the summer, unless you're very meticulous (nice way to say anal) about letting the tops of your pots dry out. put a fan blowing (gently) across the tops of your pots, it helps them dry out faster, and the wind fucks with the gnats. some DE or gnatrol on top of you medium also helps, and they go for the yellow sticky traps, which helps keep the population down, too. but they'll go in and out of your drain holes as well, they're pervasive, but you can easily keep them under control with a few simple steps. if they get very bad, pull a stocking over the bottoms of your pots to cover the drain holes, and tape it in place.

it's not the ease (or lack of it) getting the plants in and out of the pot, its the damage to the roots. they like to grow into the pots, even if you don't pull any big ones loose, you're going to lose a lot of those fine hair roots that actually do the work.
the whole burying the pot thing isn't my idea, i kind of stole it from the guys who use 100 gal + ones, they just drop their 20 gallon units into 60 gallon units, then drop those into the 100+ ones, the roots just grow through the sides of the old pots, since they aren't getting "air pruned"..

nothing yet but I'm leaning towards getting a waterfarm. Coco would be my second choice.

Ok i got you man.. i see what you mean..thanks for the explanation..i am sure that does happen.. i try to transplant before the roots really set into the pots.. dirt usually comes out in one big hunk.. anyway thanks for explaining and i do see your point.. now you got me thinking about doing plastic pots.. lol.. just been using fabric a while so i am kinda stuck there.. not a big fan of change but can and would if it makes a difference.. you always have great info Roger..Peace
