Pro-Mix Potting Soil

NoLogo · 07-18-2008, 04:55 PM

Hello everyone!

So as usual I am planning my next grow way in advance lol, anyway I found this Pro-Mix Potting soil at my local hardware store and I remember reading about it in a few forum posts before.

This is the specific type I bought (not in that size, i got a 28L bag, thinking about going back getting a couple more bags)

Premier Horticulture – PRO-MIX growing mixes & Peat Moss: The ultimate growing performance

Anyone tried this soil before and had success with it? I'm sure it will be fine, just want to know if anyone has had any crazy good grows with it, or if you have any tips on adding worm castings or not adding things, anything along those lines.

Thanks again!

You can play with the amounts, which is the nice thing about making your own mix. This should get you started:

10-20% Perlite: for added drainage and soil aeration. Use closer to 20% for flowering mixes.

10-30% Worm Castings: for nitrogen, added micronutrients and aeration.

1-2% Dolomite lime: Pro-Mix BX Seed and Clone has this already added! So I don't add it. Basic Pro-Mix, to my knowledge, does not. Dolomite lime helps stabilize the pH of the soil. Pro-Mix is mainly peat and as the peat breaks down the soil gets more acidic. Dolomite lime is used to combat this natural lowering of the pH.

2-4% Kelp meal and/or Guano: For additional macro/micornutrients.

I've added nothing but perlite and had great results. It's a quality soil and highly recommended by a lot of growers.

I've been using Pro-Mix BX for a couple years and have had good results.I think i'm going to add some perlite to air it up a little..
I used to make my own soil and did good but I found Pro-Mix and am happy with it.

To be honset I have seen a mother that was over a year old and was in a bucket full of 80% perilite (the white balls). I don't know what else was in there, but it looked weird when I first saw it with a bucket full of white balls.
