Can you use a 1000 watt MH to root clones/seedlings?

    My friend was wondering, can you root seedlings under a 1000 watt MH?

    you could, but it would be an obcene waste of energy. use 6500 K cfls.

    What he said. Your seedlings don't need that much juice until you start the vegetative period hands down.

    you could, but they dont need it and it could actually end being bad, you dont want your clones focusing on photosynthesis.

    The reason my friend was asking is because he is already running a MH with only 6 under it. He figured he'd just add the seedlings/clones under the 1000 watt MH.

    Would it be a good idea to put a clear dome over the smaller plants to help protect them from heat stress?

    Naw, just keep them as far away as possible like 4 feet or so.
