100% Hemp Stalk Growing Medium

There is a garden composter manufacturer that also sells bricks of coconut coir and hemp substrates. Here are some descriptions, keep in mind it's also used with composting toilets and at the same time try to keep that in the back of your mind.


The Green Bag = Peatmoss/Hemp Mix

Compost Sure for composting toilets comes in an 8 gallon (30 Litre) bag. It consists of coarse peat moss and chopped hemp stalk. Compost Sure has an added advantage over homemade bulking material - hemp. Hemp will decompose where wood shavings and peat moss do not - giving your compost a longer residency time! More importantly, it saves you the time of making your own mix.

What do you think? Worth a try? Already been done? Cannibalistic?

Thats pretty interesting, it might be worth a call to the company to ask if they really dont add anything else to it. its cheap enough that it would be a fun experiment. the problem i see is figuring out a fertilizer regimen and maybe any residual pesticides the hemp growers might have used.

I never thought about calling. I'm going to have to now that you mention it.
But i agree, it's definitely cheap enough to be a fun experiment.

This is what i'm thinking for an experiment. using liquid fertilizers.
Test mix #1: 100% hemp (blue bag)
Test mix #2: hemp/peat (green bag or 50:50)
Test mix #3: hemp/coco (50:50)

nice! what ferts are you thinking of using? a coco fert for the coco mix?

there isn't any information on hemp as a growing substrate except i remember reading a long time ago that hemp core substrates could be used in commercial fields to correct nitrogen depletion leftover from years of conventional fertilizer use.

I'm thinking:
HN Natural line vs GH Veganics line
use calmag/equilibrium with every watering, ro water

then a control... like foxfarm
