I grew ~20 Bhut Jolokias & Trinidad Scorpions in 3 different soils. Just thought I would post the results for people looking for a soil for growing their hot peppers.

From Left to Right.

1. Cheapest potting soil from Lowes /w added perlite. Hapi grow I think.

2. Miracle grow potting soil

3. Sun-shine Mix #4.

The picture is accurate to all plants and their respective soil overall. Miracle grow was the best performer followed by Sunshine mix 4.

All grew under 6500k T8 lights /w heating pad.

Last season by Bhuts would stagnant recently after germination for weeks and weeks. (looking like picture 1)

Now I know why.

I'm going to add some bio root, and partial strength fish fertilizer to the cheap stuff to see if they catch up with supplemental nutes.
