>>300430Carolina Reaper is a hybrid. The seeds from it can end up being plants like one of the original grandparents, instead of the parent plant. Essentially 1st gen hybrids are best, 2nd gen okay-ish, and 3rd gen not worth your time.
>>300442Yes, but don't use tires because they leach several heavy metals and other crap you really don't want being in your food. You can use just about anything to make a potato tower. Easiest method is some fencing, straw, and soil, like in this image.
