Simple grower here. Over the years, I've grown in anything organic available from miracle grow,
OF, Promix, Biobizz, Humboldt....and a few more I'm sure. We had a grow shop in a nearby town, and until they got busted, the owners encouraged trial and error. I eventually settled on Humboldt Soil....very light ammendments and easy to use.
After the grow shop got closed, I started using biobizz light mix. It does the job straight outta the bag. I used DI water for 2-3 weeks, the push light nutes.
Always reading up on alternative grow mediums but simple is where I'm at.
