Give it a go!

I really like the whole Simply Professional line of products, the grow, transition, bloom cal mag and boost (haven't tried the micro nutrients), all mix and dilutes well with my water solution unlike some liquid fertilizers that turn into sludge and separates from the water and clogs up my water pump & drip emitters. I would highly recommend Simply Professional formula for any medium 👍🏼
