    Default Stealth Heating In The Micro Environment

    Hi everyone,

    I'm cloning & vegging in a PC Case (not one of the larger Server cases, a regular ATX computer case) with an 85watt 65k CFL running at 18/6. During the 6 'off hours' in the Winter, the case drops to ~15°C... I've read this as the boundary for safe low temps... but would love to learn more.

    During flower, however, I'm reading that the lower boundary is closer to 20°C, which has me thinking about efficient ways to keep a PC case (or other similar sized grow chamber) warm.

    One of my potential solutions would be to either lay out a seedling mat

    Another option would be a small reptile heat rock put on a standard timer, or one of the above temperature controllers.

    Would love to hear your thoughts on how to resolve this before I go digging into my wallet. Anyone else had to deal with harsh winters? How did you solve it? (Bonus points if it would work in a micro environment)

    Come along for the ride as I run through a full cycle of a Perpetual PC Case - 12/12 From Seed.

    Old thread I know but I don't believe in starting new threads when everything can be in the same place. I'm in the same boat as you were. How did you find the heat rock? did it do the job?


    New PC Build coming soon

    A Bio Green heat mat might do the trick?
    Would help to insulate the box on the outside or at least put it on top of some styrofoam to not loose too much heat through the floor.

    Why not use a tube heater like I say in your HID Ikea stealth grow?

    So just been digging deeper, my old tube heater is 2ft which is too big for the case, however, a 1ft tube heater should fit fine.

    So I'll be buying a 1ft jobbie, question is do I get one with a thermostat built-in to keep temps in the 20's during lights off OR should I dig out and hook up my Habistat Pulse Proportional thermostat to it?

    Thoughts Cleargreen/all?

    Regards

    I like having the thermostat. Makes it easy to switch off if I'm moving things around as I don't have easy access to the plug socket. I could unplug the cable, but it's easier and prob a bit safer to turn the thermostat down to zero.
