Heat 'em up! (for you nervous northerners)

So in response to the many posts about growers worried about frost and freezing temps before harvest, I offer to you my tried and true method to ensure the most amount of time for your outdoor grow to finish. It helps to have easy access to your grow but if your feeling froggy it works anywhere. If you have some trekking to do this won't work for you.

Someone mentioned a while back about finding a way to keep plants warm during cold nights without risking fire. A great point abuot painting rocks black to absorb heat to disperse overnight is a great idea, but I step it up a bit. For 3 years here is what I have done:

Find a few good size rocks and put them on a section of ground you don't care about. Proceed to light a big ass fire on top and keep that bastard blazing for about an hour. Let the fire die out naturally and take the rocks (hot as hell, use fire tongs or something ) and place them under your plants. I prefer to lay out a layer of stone under these rocks to help prevent roots from burning. Under cold temps, this will heat the immediate area around the plants all night, provided you use good size rocks. In case of frost, use the same technique but cover with plastic or some sort of barrier, careful to not touch the rocks and create a breach. I've never used this during a good freeze because you simply can't keep the roots from freezing, unless you use river bed gravel and spread it all around the base, but I'm not brave enough to try it.

Helpful info to give you piece of mind. Again obviously this isn't for everyone, but it will help greatly for some. Tried and true, never had an issue. Happy growing to full term!

I should mention a cool down period of about half an hour. Putting that hot ass rock under there could cause damage.

I always go for early flowering stain to beat the cold weather. most of mine are done and curing as I write, but nevertheless, that ain't a bad idea if a fellow had the time to do that and no one asking questions why the fire???

how else are you going to heat up huge ass rocks..?
your bic..?
or just a super long extension cord to get the electric grill out into the woods..?

?????

I think he was implying that an outside observer may find it strange that you are cooking rocks. I am an indoor grower but if I was in that position I think it is a great idea. As a scout leader many years ago we would heat up rocks to put in our sleeping rolls on cold nights. A small comfoert when your nads are freezing.

so does this work if your plants are between 6 and 7 feet tall?

It works by keeping the ground and anything above the rocks warmer, 6 to 7 feet might be pushing it, I lst all my shrubs so they never get higher than 4 feet.

lol should i send a signal flare into the air at the same time to make sure the fire department sees the smoke in the middle of an uninhabited forest?
