One clean and sanitised bucket with a tight fitting lid. Coco coir weighed and broken up in to bucket, Gypsum weighed and added, Vermiculite weighed and added. Give this a good mix then add the boiling water, fit the lid making sure its nice and tight and allow the mixture to cool down over night. Cakes will be made tommow ✌️

Have you noticed an increase in contam from using additives in the coir? And does it have a noticeable affect on yield or something? First time grower Im starting very soon just doing lots of research first

There's some correlation data that adding gypsum may increase potency in a minor but measurable way. It's not causation and hasn't been tested in any kind of controlled fashion but in cultivar cups that provide the sub recipes, those that added gypsum had almost across the board a slightly higher average potency than the same strains submitted by other growers without using gypsum. Take it with a grain of salt as there could be of course other factors in play but it's enough data points for me to keep using CVG.

Thanks for the info! I plan on doing two of each strain I bought just in case something happens to one, so I might add gypsum and vermiculite in half of them and see if I can tell any difference

Gypsum plays no measurable beneficial role in the cultivation of Cubensis, it is an added cost with no benefits and can be skipped every time. It does nothing beneficial whatsoever.

I've done GTs, B+, Mazatapek, and JMF. All in CVG substrate and had great results every time. I wouldn't be able to compare this substrate with another as I just do what's worked before and luck for me the first time was bang on 👍

CVG (coco coir, vermiculite, gypsum) is a pretty standard mix and won’t make contam happen. Philly golden teacher on YouTube has some great videos for beginners

Definitely gonna check them out, thanks.
