anyone use oxy-cal?

I saw this at the local hydro shop:

Oxy-Cal, (500 Grams) $19.95

"Oxy-Cal releases oxygen in soil over time to increase microbial activity for a healthy root system, superior nutrient uptake and more efficient use of water and nutrients. Protects seeds and increases germination."


I've search the forums with no hits on that product name. I'm wondering if anyone has any experance with this product. Looks like it could be very useful for us dirt farmers. Basically time release O2... I'm tempted to pickup a bucket as it's only $20.

Wow no takers. I had a feeling that would be the case. I might try some then next season (im outdoors). I'd be glad if anyone who might of heard something would respond. thx.
