I have a decent amount of space. I have enough irrigated space to put in 5 more 40 x 60s after this of I wanted to. Even though I would never want to remove all the trees, I could put 24 more greenhouses this size in the back of my property.
I've been growing super hot peppers for about 6 years, but I have had a certified nursery here for 30 years. I actually got my first two ghost pepper plants as a joke. My next door neighbor was bragging about eating a habanero, so I thought I would grow what was the world record hottest at that time and give it to him to eat and burn his face off, which he never did. So, I ended up selling ghost pepper seeds and made 14 times my money in the first 3 months, so I kept growing them. Each year I have doubled the plants, and each year I can sell everything I can produce and only with just having a website that doesn't even have a "cart" I didn't want to rush into this because I have gotten into certain plants from time to time that were popular and then lost their popularity. Each year I have learned important things about the business and learned some very special cultivation techniques, so I am glad I didn't jump into a big operation and spend a lot of money at one time. I just cleaned out some existing greenhouse space and grew from there. Right now 1\4 of the other greenhouse is filled with pepper plants. I am already selling fresh peppers to 5 different taverns for chicken wing sauce, and 10 different sauce makers, yet alone just regular people who like hot peppers. I turn down business every month just because I didn't have enough peppers to take care of what they wanted, so late in 2015 I decided to go for it and triple my production. No, my peppers are not presold but I am confident I will be able to sell them. I have kept from doing any extra advertising in any way because if I increased the demand, I couldn't have supplied the peppers. I am still going to grow into this operation. I'm not building the 40 x 60 all at one time, so I will still grow as I get more demand. It isn't like I had to spend a lot of money. I'll have about $600 in the 20 x 60 greenhouse, I have 20 yards of my special soil mix sitting around and have a 40 x 20 x 5 pile of used pots still laying around after my landscaping days.
I have found that super hot peppers go for a lot more than other peppers. You can get orange habaneros at the store for $4.50-$5 a pound, so the grower would get much less. Supers wholesale at $20-$25+ a pound. My local competition sells them in small flat rate boxes that works out to be $60 a pound, so there is a lot of room to work with.
