    So, I just watched your video about the hydroponic jars that do not need an air pump anymore! Now that I've seen this one too, and understand the rock wool thing I have a question… Can I do something heavier like tomatoes?

    Why have you stopped making grow videos? I came upon this video and checked out your channel hoping to see more on how to grow things like lettuce, peppers, etc, since you are called "TheGrowGeek", but it seems you have given up on growing? Just wondering if you have anything "grow-related" planned anytime soon? Thanks.

    Hi! Thanks for posting this video! Two questions/comments:
    1) Have you re-used rockwool for seeding with good results?
    2) have you considered using Coco-coir? do you have any opinions about it?

    Thanks again!

    Do you see any danger with inhaling the dry particles of rockwool? I don't see it as any more dangerous than living in a house built before the 1970's. Nice video. Thanks. I just ordered my first batch of rockwool from Amazon!

    Do I understand correctly that I wouldn't need to use clay pellets in the pots for growing hydroponically? Would the rockwool continue to hold the plant to maturity and harvest? Thank you for helping me. Peg
