Currently i have a 6 plant hydro setup with a 400 watt mh/hps and a 6x3x9 room and i am moving soon to a new house. My new room is going to have 12 plants with a 1000watt MH/HPS but i wanted to turn this storage space into a preop grow room using my 400w MH under 12 plants 2-3 weeks before the other room finishes, and then transport them to the real grow room under the 1000w. My question is, will 400w be enough for the first 2-3 weeks or if so could i do it like 5 weeks even? the temp in the storage room is cool so with the light should be optimal with a fan in there. if not, another 400 mh in there would work i would think?

400 sounds good to me for that many plants vs your space.

Looks like plenty of light to me!

400w should be plenty. from what i have read, it seems that using a more "mild" light during the first couple of weeks might actually be preferable. i have noticed some growers regularly use a smaller wattage bulb for the seedling stage, then switch to a higher wattage bulp for the veg.
