Growing medium

I just go to the nearest recycling place and pick up composted soil. It's free and highly nutritious, and a 10 - 15 liter pot of it should be able to last from seed to harvest with autoflowers without the need for fertilizers. Can definitely recommend for a first time grower, instead of spending money on bags of grow medium.

I too am a first time grower. I am finding that Coco Loco is a great medium to use and also has been very user friendly thus far. It has great water retention values and I hear it is hard to over water. So far I am having wonderful results (I think) and no issues other than I tried using nutes way too soon and I had some brown spotting on the leaves. They have recouped pretty good. Luckily it was super diluted. So Coco is great for a first timer. Good luck! 👊

A light mix soil for autos is great bio bizz or Dutch pro are two I’ve used both seem good I add an extra 10% perlite to the mix for drainage but the light mix will get you all the way threw veg without having to add nuits
