I recently picked up some of this "Mighty Crobes" stuff off ebay and was quite skeptical, but it worked very well I.M.O.. Anyways, I tried it out on 100 clones I took off my new mendo afgoo mother from Oaksterdam.....long story short... they ALL lived and were super healthly. Highly recommended....
