:thumbsup:I use them for preparing soil for grass or a garden Outside. It reduce's use of nutes and water. The theory is the little salt rock shape crystal will retain water and 'feed' and release and the soil gets dry.

I do like it in the grass mostly, in the summer. :jointsmile:I've never tried it with mmj plants.

Somehow, due to the intense specific needs of the plants, pushed to the limit by the grower--not sure of the result.

What would concern me is: The element of release from the crystal back to plant and the rate?

:rastar

If you had to flush them I think you'd have to pick them out and do it literally.
painretreat Reviewed by painretreat on . Water Crystals Has anyone ever heard of or tried using these lil things: Water Crystals for Healthy Plants & Crafts. I was wondering if anyone knew anything before I try them. I plan on using em for cloning and ditching the rock-wool? Any thoughts or opinions? Rating: 5
