My younger one brought a hyacinth home from school when she was about seven, and I told he to give it plenty of light. Her solution to that one was to bend a table-lamp over so the buld was an inch from the plant, and leave it on permanently. Somehow she managed not to kill it, and it bloomed well in the end, though the tips were rather scorched.
Wait till it warms up a bit, harden it off by moving it to an unheated area like a porch, then put it outside when it's warm. After a few days of that, it should be ready to go in the garden.
