My friend does soiless grows with rockwool chips and perlite... It's hard to get rid of the garbage.
With soil you can dump outside in a garden.
I'm not big on the ocean forest soil, way too expensive for larger scale. Even pro-mix is too expensive for me... I just get sphagnum peat moss, perlite, and earthworm castings and mix it up... 50/50 moss and perlite, then a 20# bag of worm turds per 2 bales each moss and perlite.
Then I add the Dolomite Lime to bring the pH of the soil to the proper range.
It's really, really cheap if you do it this way...
Peat Moss- 9 bucks a bale
Perlite- 15 bucks a bale
Worm turds- 15 bucks 20#
Lime- 5 bucks 20#
-This mix makes approximately 60-75 gallons of soiless mix.
I line the bottom of the pot with 3 inches of perlite, then fill with the mix.
Feeding is a little more regular about 2-3 days between waterings, and the airy soil is good for roots. I don't pack it into the buckets, just lightly pour it in.
-But I'm sure you knew this...

I forgot you're following my journal somewhat. My bad
