I kinda follow these grow outs a bit, seems to me very few ever turn out good. The one thing that I tend to see happen a lot, that I really don't understand. The grow out participants pick one person to grow the corals out, instead of splitting the corals up thru the grow out participants. The grow out tank starts having problems and the next thing you read about is they have lost several of the corals in the package.
That's great if everyone is local. The problem with this is when you aren't, then the shipping costs really add up. Instead of one $50 charge to ship them to the grower, you have $50 to each participant. Then, once they are grown out, instead of $50 to ship them to each participant, you have that times the number of participants (minus 1), squared.
For instance, say you have a growout with 5 people, one of them being the grower. If you send them all to one grower, you have $50 for the initial shipment and another $200 for the shipments when the growout is finished, for a total of $250. If you ship them to each person to grow out a portion, the initial shipment is $250 plus another $1,600 for everyone to ship out theirs to everyone else when it's done, for a total of $1,850 in shipping costs!
I think that growouts are a good idea in certain circumstances. You need to have a small number of participants so that it doesn't take too long, and you need a responsible grower. I disagree about necessarily getting a fast grower. The faster a coral grows, the quicker the prices drop and the less it is worth doing a growout.
