Only peat as growing soil

Has anyone growed cannabis in a peat soil and has some expierence with it and can tell me? Im growing in a greenhouse btw

Peat by itself is not used by anyone I know to grow in. Not only weed but not by any growers.
At a minimum it needs some amending for drainage and pH adjustments for cannabis.

Here are a couple articles relating to growing in sphagnum peat moss…

Hope this helps


It’s called Promix. Best substrate ever.

402 grams of flower.


I love promix too.
But its not “Just Peat”
That was the question in the title…“Only Peat as Growing Soil.”
Promix says on the bag…

Contains: Canadian Sphagnum peat moss (65-75%/volume), Perlite—horticultural grade, Dolomitic and Calcitic limestone (pH adjuster), Wetting Agent and Mycorrhizae – endomycorrhizal fungi (Glomus intraradices).

Maybe the question was not as Literal as I took it. :crazy_face:

Im litteraly growing in full percent peat soil

You will be constantly chasing your PH with peat as it sits around 3.5 - 4.5 which is miles out. Promix is what you will end up with or something similar.
