    flowering with MH 400 watt

    I am having a problem getting my HPS 400 watt bulb to fire so I am going to use my MH 400 watt bulb to flower. Will this work or am I just wasting my time. Also I know both bulbs I have work but the HPS wont turn on, yet the MH will. Is this a problem with the ballast or what? I dunno but thanx and peace.

    The MH will work but it will be in no comparison with the buds you might have had with the HPS.But yes it will work, good luck and happy growing!!!

    Is the system made to use both MH and HPS bulbs? If not I don't think you can just swap bulbs in an MH ballast with a HPS bulb and visa versa.

    Yeah the MH is a conversion bulb. Budman will the plants take longer to bud and how much quality do you lose? Thanx man

    The plant will not take longer to bud, just will not be as heavy and compact. You might lose a lil weight, the one thing thats for sure is that it will not be as potent as it could be. But you will do fine, im sure the stuff you will grow will satisfy you when the time comes. Good luck and happy growing!!!

    Sure you could use 1light for the whole grow, but theplant grows better with the MH during veg than with the HPS. Then wen you start flower you switch over to the HPS which makes a giganitic difference in yield.
