Hardy hibiscus; Blue River II seeds and Luna

This past Summer (07) I bought some Blue River II hardy hibiscus and Luna Red and Luna Blush hibiscuses. All of them produced many, many seeds. I couldn't wait any longer and I planted some of them 12 days ago. Yesterday I noticed them growing like a weeds. Seeing that I got an urge to plant all of seeds, which I did today.

Now, Question; what should I do to make those young fragile plants from getting to leggy, to tall and fragile. How to slow them down. I want them to take their time until better weather comes until April. I am afraid they might die latter on.

Please guide me step by step bcs I really need your input.

The room where I grow them is 24/7 under artificial light and temperature is at about 25/26* Celsius.

Thanks to all, Radovan

I think you should lower the temp to about 20* and the lights should just be about 4" from the top of the seedling. Seedlings get leggy in low light and high temps

Make sure you give them some time with the lights off as they need to rest for a period just like humans. 15 hours of light I think is the most they should get a day. The most critical in my opinion is the position of the lights though. Good Luck!!
