2 gallons of compost
1 gallon of Coco coir
3 solo cups perlite
1 solo cup of vermiculite
3 cups EWC
1/2 TEASPOON of Yucca
Amended this blend @2 tablespoons per finished gallon of mix.
I used quoddy blend by coast of maine for compost and bricked coco that was reconstituted with the yucca wetting agent. *Please Note* this is prototype soil at the time/date of this post. But, it is basically the same ratio I used for veg, just more EWC and different mix of Dr Earth beings we are close to flowering. Hope this gives you an idea where to go with your own recipes.
