Best seed starter in the market in my opinion , I always get great germination using Hoss seeder soil !!


I think it will do well. Just started seeds indoors today.

Chunkier Than Expected But Overall Does Well

My seeds were a little slower to germinate in this mix, as it is kind of chunky and a little more difficult to push through initially, but once established the seedlings are growing well. I think the added nutrients and mycorrhiza in it definitely help! I have not had any damping off or mold problems in containers where I used this mix and no fungus gnats!
