will any of those ways to keep a plant short raise my heat signiture or lower it ?? and what about bending a plant over so it grows on the ground ??

supercropping ?

Check out my mushroom grow!

lst, topping, fimming will all help keep a shorter bushier plant. But they will not change your heat signature. But if your only growing one plant, helicopters most likely wont even bother. They are looking for growing with huge feilds of rows. One plant isnt goign to be a big deal man.

Grow on : )

what about 70 lol

plants don't put out heat, they just don't, where do kids hear this crap?

Beaner is right. See?

What does Leo look for?



Officers are trained to look for hot spots on walls and windows, unusually warm foundations, exhaust emissions from vents and chimneys, and warming trends typical of marijuana grow operations. Leo will wait until evening or early morning (when the grow is up to full temperature and the air is cool). He will also look for light leaks, smells and other info at this time.

Note: Leo will try to image a suspected grow-op from all angles, but is only legally able to do so from public property (ie. Sidewalks, roads, public paths, etc).

Note: power companies occasionally image power pole transformers to see if they are abnormally hot (problems), and to source power theft.

The best way to keep a low profile is by paying your bills in full and on time, keeping your property clean and in working order and being a good and quiet neighbor.

I have read numerous times that marijuana plants give off a different heat then other plants. I will go look it up right now : )

yes they do, all living organisms produce heat.

i mean seriously do you people think cops are just using binoculars or some shit when in the air?

The original question concerned whether a short plant would raise of lower your heat signature. Here are ways to combat that.

How do I mask my heat emissions?
Note: Small grows (under 2000w) would probably not emit enough heat to warrant the effort or expense.

Note: Reducing grow room temperature will reduce heat emissions; however, the grow room will still be warmer than surrounding basement rooms.

This technique creates a false wall to contain cold air. Interlocking rigid foam panels prevent hot grow room air from contacting and warming house walls. Cold air is blown into the gap between the foam and the walls for maximum protection. The wall's exterior will appear cold to an IR camera, indicating a negative for internal heat.

· Partial room (insulate exposed walls only)
· Room in a room (entire rooms are insulated)

*Floor. Concrete foundations absorb heat readily. Build a sub floor to raise the entire grow off the floor.

*Walls. Use interlocking 1.5 or 2 inch foam insulation along all exposed walls. Place the insulation 1-4 inches away from walls, fit foam panels from floor to ceiling (some cutting may be required), and blow cold air into the gap. Seal seams and corners with tape. Cover walls with Mylar to reflect heat back into the room.

*Windows. Windows are essentially uninsulated, so you must fill the gap with insulation. Draw the curtains/blinds, add black poly behind, then add insulation.

Drawing description
A Public property that Leo can image from

B Internal basement room. Grow room heat will still be noticeable, and this side needs protection.

C Safe basement rooms. Put ballasts and reservoir outside to minimize heat

D Partially insulated growroom. The pink band is the interlocking foam insulation, the blue band is the cold air contained between the insulation and the house walls. The window on the bottom of the picture can be open to allow cold air to enter the air gap. Room temperature air can also be blown in from an adjacent basement room through a hole in the foam panels.

Hiding the Exhaust
Safely exhausting hot air is difficult; Leo looks for unusual heat emissions coming from opened windows, chimneys, dryer vents and other handy places. Note: running exhaust to outside sheds, barns and tree stumps is well known to Leo.

Exhaust down the sewer Every house has a sewer vent standpipe. By venting down the sewer, the exhaust will be chilled and smell is distributed amongst you and your neighbors. The sewer cleanout access is often a 3-way 4? abs T with a threaded cap somewhere in the basement. Remove cap, and hook your blower to the T (A 4 inch to 3 inch adapter funnel may be required) and run blower 24/7. This will not affect normal use of the sewer

Cool exhaust with water
Place a wet towel (wicking water from a tray underneath) partially over the end of the exhaust. Spraying water inside the exhaust pipe works as well.

Underground exhaust
Running the exhaust through a long, buried pipe helps to cool the air. Perimeter drains can be used for this.

Water-cooled lights
Running water cooled lights is very effective; IR heat from the lights are washed down the drain. Water cooled light systems are currently difficult to source, and have drawbacks including cost, condensation and leaks.
