Fridge Grow / Clone Box

Discussion in 'Do It Yourself' started by fishwater, Aug 4, 2014.

  1. Hello everyone.
    I have been lurking here a while and just getting started on my first REAL grow.
    I wanted to find a non working fridge with the freezer on the bottom, but I couldn't find any so I picked this one up from a dealer for $20.

  2. So I gutted the compressor and all the fins from the bottom, which is why that hump is behind the crisper drawers.
    That also makes for a small footprint on the bottom of the veg/bloom box.
    And I also wanted the freezer on the bottom to use for a cloning area and for my nutrient reservoir.
    So I had a set of legs in the shed that I bolted to the top of the fridge and flipped it over.

  3. Got the light mounted to the new top of the fridge and the wire ran out an existing port to the ballast mounted up (top).
    Makes perfect use of the otherwise wasted space if the fridge were right side up.
    400W LPS and MH

    I have an AeroGarden I am planning to use for my germinating/cloning.
    I broke one of the bulbs so I think I will lose the stock top light and wire up a couple sockets up as high as possible and use better grow CFL's

  5. There are these three holes in the floor that go straight through to the freezer, the center one is around 2".
    I Picked up a couple containers at Target today.The large container in the grow area will get a drain installed with a hose running the runoff nutes from the 6 plants being fed back to the res that will reside in the freezer area..

  6. I can adjust the legs I used on the cabinet to slightly lean to the rear to get all nutes to drain .
    I Found the perfect sized container for the pump to go in, but I will have to paint it black.
    Then just run a 1/2" line through a hole I will drill through the floor of the grow cabinet and create my water bridge with 6, 1/4" lines coming to a drip ring around each plant.
    I am thinking of using 6 - 8" x 8" Rockwool blocks….???
    Any thoughts guys?
    FIRST build/grow here… I'm all ears.

    I will also need some input from y'all concerning ventilation/fans etc
    There is a great place to exit at the top, just to the left of the light shroud.
    Up behind the cabinet where the compressor was is a nice big area for a big charcoal filter.

  8. I think I will also cut the floor out and remove the insulation to fit the shape of the large tray to rest that tray directly on the hard ceiling of the freezer area.
    This will gain me almost 3 inches in growing height.
    Still thinking about this MOD ???

  9. I want to do a SrcOG by inserting my screen frame above one of these ledges for the old shelving.

  10. The unit is really clean and white inside.
    Do you think I will have to line the inside with foil or reflection material?
     
  11. Well, I won't gain 3" but I will gain almost a full 2" by cutting out the floor and insulation.
    The "floor" already has a 1" recess, but I think I will go ahead and do it so I can lower my scrog screen a little more.

    OK… back to ventilation.
    I saw a 6" inline fan I like @ 240 CFM $25
    So, I did some figgerin.
    Cut in a 6" hole as far to the inside left as I can going straight back to the compressor area.
    On the inside, there will be a short extension coming straight at you then an elbow turning right and coming close to the light bulb.
    With 2 intake holes located below the canopy, the air will be forced to pass right by the light bulb.
    Then immediately on the outside, another elbow turning to the left (back view) directly into the inline fan then into a big carbon filter. (crappy sharpie drawing)
    With a width of 30 inches, this should be a breeze to accomplish !

    Thanks dude!
    Post a pic or 2 of yours if you want.
     
  15. There is another 2" above the top of the fridge.
    This is where I will most likely mount my ballast for the 400w HPS/MH.
    After I have everything mounted where I want it, I will put a thin plywood top on it with some kind of black plastic facia to hang down over the old toe kick area and make it look more like the top of a fridge.

  16. Cutting through the metal casing on the back to get the vent pipe through won't be that hard.
    I dimpled the metal pretty good by just striking it with a firmly held Sharpie a couple times.

  17. I think i will drill one of my intake holes right behind this (non-working) fan and as the air passes over it , the blades will spin giving a little vortex action in the small clone room ???

  18. I am using a 6" inline on my fridge.Mine is a little bigger area(side by side) I have my inlet (6")plumbed to my ac duct work ,then 2 4" outlets at top of fridge going into a manifold box which goes to single 6" .This then goes to my 6" Hydrofarm fan with speed control.My temps with 230w led,fan at 1/4 speed are between 70F and 76F with light on.
     
  19. As far as white verses reflective material,your guess is as good as mine. I did mylar film,what a pain in the ass it was.Hope it was worth the trouble.
     
  20. I'm subbed in.
