    Default Light proofing containers

    what do you use?
    when i made my own bubbler cloner i tried a rubberized coating that never really cured and was a mess.
    I recently found out I have access to some 48 Gal plastic drums. However they are opaque and would cause major algee issues if used for rain water collection. i am wanting to line the one side of the building and interconnect them all to make a large rain collection vessle. in winter it'll keep the prevailing winds off that side and the solar energy they soak up will help out.

    If solar is a a concern, you don't want to use the metallic foil heating duct tape that I use to light-proof my 17 gallon Rubbermaid totes. Dark side panda plastic might work, if, you can find a suitable adhesive.

    Going to try and use one for bubbling chrlorine out of the domestic water supply, so it won't be outside.
    Hadn't thought about the real duct tape, rather expensive but seems like I have a spare roll, panda film good idea!

    I use (2) 45 gallon roughneck garbage cans for my R/O res. Grey bins are food grade plastic.

    Paint doesn't always stick well to plastic, so it that's the case I'd suggest scuffing the outside first with fine sandpaper so that the paint can adhere stronger and resist flaking.

    for the trouble and ease of cleaning opting for a wheeled trashcan.
    They are thick and black.

    Stick a 100W bulb inside and turn off the rest of the lights; if the 100W does not shine through you're good. If it does shine through use foil HVAC tape, cover with duct tape to protect against scuffing.

    I flipped it upside down in the store and was all but dark underneath.
    Wanted to keep it with the veg/clone area so light will be an issue if not dark enough.
    420 grower; did you do any prep to the plastic? how many coats? ect ect.
    How well did it work to lightproof things?

    U think we sprayed it twice,but no prep other then just cleaning the box,sprayed just the outside,flat black,held up until the cops took it in the raid,lol,I'll probably not build another,I don't clone alot,but I still have great success with just filling a flat with 1/2 inch of water,cuttings,rapid rooter plugs, root powered and cover,stay at 80 degrees or so,roots in a week or so,peace
