    400w hps question

    so building a flower room, was given a 400w hps light yesterday, i did hook it up and place in my veg room until build is done but the question of the day is, what size hps light should i use for a room that is 9'x11'x7'. i am thinking of buying a 1000w hps light off amazon for 159 (see attached link).

    the problem im wondering is would it be more advisable to buy 2 600w hps lights ( few bucks less then the 1000w hps light). i am also trying to not spend a fortune on the energy bill but i do know adding an hps light im looking at a high bill already, unfortunately by adding hps to my set ups. so would a 1000w light be suggestible to supply that room size, or would i be better off adding two 600w hps lights for that size room.

    the advantages of hps surpass the disadvantages of having it and i feel that it will increase the bud production in the long run. im just not so sure on how to go about this so that way i am able to produce more yet cover the amount of plants i plan to grow (12-24). I dont plan to add 24 in the room at one time but rather added a few plants a week or every other week, that depends on other factors as i go along.

    however i do see that the 1000w hps will cover more area rather then the 600w hps but if i add two 600w hps it will cover more area then a 1000w hps. if i go a 600w hps i can cross the lights to cover each others light path so it can cover more area rather then the 1000w. this is just so damn confusing to me, I have no true understanding or can i understand the whole production part of lights and the benefits they produce from one another. the site gives a brief understanding of it but does not go into detail and i really cant find any site that gives a more understanding (im a picture/hands on type of person). after i can understand this better i plan to put together a clear understanding of this for others to understand better (newer growers).

    If you're really planning on using all 9x11 of the floor space, I'd get two 1000-watt lights.

    two are better than one - you will get more intense light and will be stronger than one because of the specific "sweet spots" of the lights/light spread. You than can also do add side-lighting for some areas' - that light has poor coverage (corner, ect) - . 500 watt CFL's do very well for this and are very cheap to run - "1.000 bubls.com" Please keep us informed !! what will be your electric bill ? (estimate) 2 66 W vs 1 1,000 W)

      600 watt bulbs are more efficient than 1000w- and two 600s in that space will be far more practical than one 1000w.
      A 600 will cover a 12 square foot area well. Give or take a little. Aim for about 50 watts per square foot for best growth.
      You can obviously fit more than two of those lights in your space. In fact you could fit four. . But it depends how much of the space you need for other uses, and for moving around. Less than 40% of my grow room is taken up by plants and the rest is other essentials, including walking space.

        basically i like to keep the plants away from touching, but i might need to pack closer, 600w is not any cheaper then a 1000W light, sad part the 600w is only like 10-15 bucks cheaper

        need to figure your lumen or watts needed for yur space there is a formula to use " for lumens take Lx W and then x's answer by 2,000 (2,00- is # of lumens needed for 1 square foot of coveage - watt + LxW + ? then ? x's 50 = of watts needed for your space (some use 3,000 for lmens and some use 60 for watts)

      Plants look awesome! I think two 600 watts would definitely be plenty for that area

        Might just grab the 1000s and rin with it for that price. I could always switch the ballast to a 600 later

        I have a friend tht uses a 1000 watt in a room bigger than that and is able to grow enough to not have to work a day job

      Random advice from me would be to take the time to put a drain or two in the floor if possible before you fill it with plants.

      Well at least you have close access to a drain and can rig up something.

        I recommend a stay put type tarp put down BEFORE anything else is put in the room. This will mitigate any damage to floors if anything goes wrong. The tarps do not cost much at Home Depot I get a 10 foot by 25 foot one for $4.27 You could just use painters tape to affix the tarp to the floors and daisy chain the tarps to fit in your room and also slightly up the wall itself to prevent the WICKING of spills into the wall itself. cheep insurance especially if you have no drain.

          It is a laundry room though. Looks like it has a concrete floor. A perfect location for a grow. May have dirty clothes from now on but at least you'll be stoned.

              Concreate floors will get stains from the newts. as it is absorbent. Is the concreate sealed? Sealer can be applied easy using a paint roller.

                reason i am placing epoxy down on the floor. laundry stuff is being removed so it will be a straight flower room. also i have plastic i can lay down on the ground or a reflective type material.

              I've used trays about 18" across, with smart pots on risers for the last two grows, and it works well but is a bit of a hassle after watering because I have to use a Wet Vac to get the runoff out of the trays. Also put the trays on top of a tarp like "dontknownothin" suggested. It worked well too but was a hassle as I had to move the pots around once in a while_making it necessary to re-arange the tarp every so often. Now I have two plastic trays that I got at HomeDepot_ they are about 2x6 feet and 4" deep_ should work really well_easy to move around, should keep runoff manageable, protect against spills and will have to Wet Vac two trays instead of six. we''ll see. Good luck, sounds like you might be able to connect the intake/vent for your grow room to the vent that used to be used for the dryer if you are going to move the laundry stuff to a different location.
