Insulated Shed Grow! 600 watt HPS, Stealth Grow

This is whats growing in a shed.
All I know is Canada has cold winters!

Its fully insulated and pretty stealthy, 750 watt heater in there too which runs about 8 hours a day, on 2 hour intervals when the light is off.

3 plants in flower as we speak, one about 40 days in, the other 2 about 10 days.

They are on 12/12 with 600 watt HPS.

DWC (deep water culture) with bubble stones and general hydroponics nutrients.

-How much you think we're gonna yield from this momma?


For VEG 20 hrs approx 250 watts of CFLS (I have a 250 watt MH on the way). All in DWC with mild nutrients, and 2 plants in flower pots.

Clones in a humidity dome in rooter plugs with a 50 watt heat pad on 24 hrs, cloning gel, clipping clones every 4 or so days. ( although i have about 15 currently to choose from)

I plan on taking a rooted clone every 4 days and placing it under 12/12 immediately for a perpetual grow and harvest EVERY 4 DAYS (Eventually) I only just started the first rooted clone 3 days ago(no pic yet).


50 watt Heat pad -24 hrs
250watt CFL Cluster -20 hrs Veg
600 watt HPS - 12 hrs Flower
750 watt heater -8 hrs a day

Costing about 75 dollars a month to run. Hopefully it'll have enough yield to pay its self off on the first harvest. (oh it will!)

Let me know your thoughts, tips, ideas and constructive criticism!

THANKS!!

im getting alot of browning at the tips and a rusty appearance spreading over some of the upper fan leaves, any idea whats causing this? maybe sever nutrient burn?

I had an Ozone issue that caused brown rust spots in the center mainly but spotted on leaves. I added more incoming air. I didnt see much of this in pics. Looks like a great setup. One thing I would suggest is to flatten out your reflective materials so there not wrinkled. Just like foil, if it bends it might cause a concentration of light and burn.

What sort of insulation did you apply to the shed?

The regular pink R12 or R15 whatever the standard is. With a vapor barrier, its nothing top notch now but it does the job. Holds heat quite well, very quiet, and its behind a second wall in my shed. Outside temps are around -10 to 0 for high.. (celcius) and inside the shed its about +5, inside the room its normally above +20 C (68 F?)

Well the room is pretty well sealed, maybe it could be lack of Co2? Im prob gonna make one up outta some fruit juice & yeast..

As for the reflector well its kinda hard to make it flat, the insulation is only held back by a thin layer of plastic and cardboard paper, it bows and heaves out from the wall, until i add wallboard or something its gonna have to be all wavy and such

I'd be shocked if your shed is so well sealed that you're having a CO2 deficiency.. I just dont see it.

truu not on this scale..
