Ahmad Rattler is right. I'm starting up a CP nursery myself. Initially I thought I wouldn't tell anyone about my plans because I was afraid someone would copy my specific strategies. But now that I've been heavily working at it for about 3 months I realize that most people would go nuts doing this. It takes a special kind of person and liking growing CPs just isn't enough.
I can assure you that it does indeed take a lot of work and it is a very, very monotonous type of work. You have to water seeds/seedlings every day. If you miss a day here or there, some may die. So forget about taking a break for a few days here and there. It's a 7 day a week job. You also have to pot/repot plants a heck of a lot. I've found that this and all the work involved in sowing seeds is really a lot of fun, for about 10 minutes once every few days. But the rest of the several to dozen hours or so a week you do this is boring. I also have found that feeding VFTs, Neps, and Cephs is the best way to make them grow. And yes I feed hundreds of them every week. It is very boring too. Oh and setting up the grow racks for them is a lot of work too. It seems that with several hundred plants and a couple of 1000 seedlings plus a few thousand more seeds that I never run out of work to do. I work 3 days a week as a security guard and I feel like I am constantly working.
So if this is as boring and time consuming as I say it is then why am I doing this you ask? Well I have a few unique circumstances and advantages that most folks don't have whether they like CPs or not. For one thing my brain seems to not mind doing what I fully realize would drive most people crazy. When I was a kid I used to shuffle and reorganize Safari cards for fun and I'm not talking a few hundred of them. I had the whole collection. In other words I have retarded type attention span for monotonous things that most nonretarded folks don't have.
Another advantage I have that most early 20's folks don't is excellent credit. I have a 0% APR for a year with 3% rebate in 5 categories business credit card that Chase gave me in October because they didn't see the Credit crisis coming and they love making me money in general. I have 5,500 in debt that I not only don't and almost certainly will never pay interest on but actually make a little off of as well. If you have to take out a loan that it will take you a long time to repay I'd say you will probably fail at this endeavor for that reason alone. You're gonna have to sell a lot of plants and that means a lot more work than just Ebay. You won't make enough off Ebay alone. And it will take a long time to have enough sellable plants to pay off that debt. You have to feed and cloth yourself somehow in the meantime.
And lastly, the other big advantage I have is low overhead expenses. My wife and I rent 2 rooms from my parents for a mere 350 a month. My Dad is in the process of declaring bankruptcy for reasons I won't go into but nonetheless I help him out a lot with little things like food etc. so he feels duty bound to allow me to fill his house and backyard with racks full of plants. My wife also collects disability so we are heavily subsidized by the government. Since I work part time as a security guard and don't make a lot of money from it I can see how a decent amount of CP plant selling could actually make more money than I do already and though I shouldn't have the funds to start up this business I actually do.
Most people don't have all these advantages. If the never ending startup debt doesn't ruin your business the boredom can. You'll also need a salesman streak in you. I used to sell a lot of things as a kid so it appeals to me. If you can overcome these obstacles great. I enjoy this overall myself and don't doubt that I will 10 years from now. But I fully realize that most people aren't cut out for this kind of work.
