Plant tonic, a natural extract from the seeds of the caryophyllaceae family.

Anybody heard of it or use it?

Never heard of Comcat. Is it for use with compost, or hydro? I'm assuming the former?

I believe It's predominatley for hydro but I'm adding it to my canna on coco nutes at the moment. too early to tell if there's any real difference but I'll keep you posted...
