Kerry - 182 seedlings! The good news is that seedlings usually do not branch out much unless you pinch or prune them. The bad news is that they don't usually bloom for the first time until at least 3 feet tall and usually taller. If you keep your house at 72F more or less it could take 2 years or longer for some of them to bloom for the first time. I don't really know because I have not done that but I have heard from other people who have seedling plants several years old at home and they are still waiting on them to bloom. Now if you put them in a greenhouse like you are looking at many will bloom this summer. Alternatively, if you can get them into your aunt's yard in lots of sun by the first of July you could get some blooms late in the summer/fall. Somebody will need to water them regularly which may or may not pose a problem.
Good luck and let us hear how it goes with these!

Thanks for the Info Charlie , so far the oldest ones are almost 12 months and they are only 1ft and a half maybe ? My first ones are all tiny small ! I think they would have grown much more if I was fertilizing them from the day they received true leaves. I started when they where about 6 months. (I didn't know when to start fertilizing lol ) Now the other seedlings I have I started to fertilized them the day they grew true leaves look at the difference they are much younger and I started them in august or September ( forgot which month) I also have been pruning the oldest ones on a few they have been branching really nicely.
these two are the same age and are from same seed pod ( i have 2 others one is like 4 inches and the other 6 )

Older ones are on the left younger on the right



The good news is my room is the hottest room in my apt lol it gets hot sticky humid in here when I have the lights on. I am guessing the temps are any where between 77-78 ? some times I have to ope my sliding door because it becomes unbearable lol.
Do you think they will bloom on my balcony ? I think I get at least 4 hrs of sunlight
The green house will happen close to fall so I wont be putting the seedlings in there.
Davidwood , i don't plan to keep all seedlings only the keepers of the bunch , I will give some to aunt and boy friends mother and a list of other people I know who want them. I might sell some on ebay so I can recuperate some money from all of the hibiscus and hibiscus stuff I have been buying lol
1.618 I was lucky to get silver dragon , My heart almost dropped when I saw it for sell so I hurried and bought it lol
