need advice on grow box setup

Discussion in 'Grow Room Design/Setup' started by multiculti, Nov 24, 2015.

  1. Hey!
    soo... I have a closet/cabinet that is 120cm (about 4ft) wide x 65cm (about 2.1ft) deep x 100cm (about 3.2ft) in height.
    The prolem is, that I can't decide what lighting setup to use, I have come up with several options:
    1) 2x150w HPS/MH (elec. ballast) that are in cooltube reflectors and vented for minimal heat. (+ as many CFLs as I can fit in there).
    2) 1x250w HPS/MH (elec. ballast) with cooltube for minimal heat + cfls to cover the sides of the growbox, so all plants get sufficient light.
    3) All out CFLs (this option in not preferable as the yields with HPS lamps are higher).

    And the plan is to separate 1/3 of the room after the first grow for veg room, so i could have a mother plant and steady supply of clones going in to SOG, so that should be kept in mind, but it is not as important, because I see a solution for all of these set ups to break in to bloom and veg rooms.
    Every idea and all advice is welcomed and thanksworthy because, I have no grow expierience with anything else than with CFLs and our best light source of all- the sun.





     
  2. Oh and I forgot about the 4th option:
    5x45w LED panels - considering heat, this option is the best, but I have read that LED's need more space between the light source and plants than HID's. If this is the case, room becomes a major problem, as there is not alot of room heightwise.
    Thoughts and ideas anyone? I really could use a second opinion...
     
  3. Wow, it's been 4 months and still no replies, the problem is still actual so plz help people!
     
  4. What I read about LED's is that they need atleast 18' inches or plants will get not heat, but light burned, as there can be too much light...
     
  5. It can bleach the top of your colas white but no real damage.

  6. I built a box about the same size as yours, tricked it out, with intake and exhaust fans , plugins, Mylar ya da ya da , ended up putting a MarsII 400w in there, had some bleaching, , definitely will work, whatever lights you end up using, just don't skimp on your ventilation, them little boxes get hot quick
     
  7. Buy a cooltube with a 400w hps. Buy a 400w (actual) LED and see which one runs cooler.

    LED is not the answer to cheaping out on your ventilation. You need either a 4 or 6 inch inline fan with matching filter no matter what light you choose. And if you're buying that you might as well pick up a low-cost cooltube and HPS ballast while you're at it, unless you really, really, want to run LED for your own reasons. But then you can't really complain about it not being as cool as you thought it would be.

    Just sharing my thoughts on the subject, I've gone over it countless times in my head. Not trying to be a negative Nancy but it is what it is, LED is way hotter than a properly cooled HPS of equal wattage.
