You're way ahead of me. Thanks for the thread. I started 3 Sundae Thumpers in re-conditioned coco. Two died, I think from fungus gnat larvae, and the lone survivor barely pulled through. I ramped up my gnat control by adding 1 T mosquito bits per gallon for every watering until further notice. I started 2 replacements in new freshly buffered coco which seem like they might survive. I never did testers before, I think somebody is supposed to start a Mephisto test-grow thread in an area with other test-grows and grow & shows, but I didn't find it. I didn't start a thread of my own for this grow yet, waiting to see if these 3 survive.
