A short video on why I use rockwool grow cubes for my hydroponic systems,
Link for amazon deal for cheap cubes: http://www.amazon.com/gp/product/B0087SJ3U0/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B0087SJ3U0&linkCode=as2&tag=thgrge05-20
What do you do with the used cubes? Compost them?.thanks for the video
Can fungus build up ? Unto or in areas of rockwool ?
We can use coco peit instead of rock wool?
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?
Thank. You make sense when some others just make noise.
Is it possible to make your own cubes from the rockwool sold in DIY / Builders merchant stores … for home insulation ?
Can you please suggest other mediums than rockwool and their advantages and disadvantages? thanxs
Love the time lapse!
Can you just use the rock wool from the hardware store?
Also subbed! Thank you!
wow. that photo of your window side basil crop looks amazing. very nice.
Great video!
does rockwool also get fungus when seed is in seedling stage?
rock wool enemy = green algae.
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!
Ebay has 200 for 16$ ! free shipping
You are just right about the price of ROCK WOOL.
Please do more videos on lighting and nutrients.
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
