Growzorb

Has anyone seen/used this product?
it's an alternative to rock wool cubes or plugs.

I seen this on CBC "Dragons Den" ....here is the link to the pitch on an episode
He is focusing on the vegetable/fruit grow opperations, but I'm sure he knows MJ is another jewel

I've seen a white poly that was used by a friend for as long as he could get it.
He used it in Ebb buckets and it worked out great for him!
It was very easy to control pH over RW to start .

Thanks for the link as I'll pass this on to him! He wants to use it again - badly!
