Question for experienced growers

[stjr2k]

If I understand what I've learned correctly, seedlings should not be placed under HID lamps immediately.

So, my questions:

1) What would be a sufficient wattage (for 10-12 seedlings) if using fluorescent tubes during this stage?

At what stage in the grow is it safe to put the plants under the HID lighting?
