I've grown both ghost and scorpion. The ghost peppers took a lot longer to establish than the scorpions, and with that said, once they've established their roots well (second true leaf set) they seemed to take off. Never had any problems with growing. The ghost peppers love heat and humidity and I gave mine full direct sun all day. My scorpions, I gave them only morning sun for about 5 hours direct with afternoon shade and I have scorpion trees now. They are ridiculous producers! I personally stay all organic and only fertilize with chicken shit during veg and then switch to a compost tea mixture with a few additional supplements. Hope that helps!
