Half of a 3 liter bottle as mini greenhouse?

Hi. I just had a quick question.

Has anyone ever thought to use a 3 liter bottle with the top cut off ( With machete ) and turned upside down, maybe slightly buried as a small version of a greenhouse while the plant is young, so that animals can't eat them?

If so, how did it work out?

I have several deer, squirrels, and the like around my grow area, and its still a little cold here. Im thinking that when the plant gets about 10 inches, the deer wont bother with it as much, and the bottle will keep some heat in until it warms up. is there a better way?

EDIT: Also, how does a large ( 25 gallons ) clear container turned upside down over plants work? I have about 4 of them in my garage.

Hey nap, welcome to riu.

I've thought of this myself and think it's a great idea.

(careful with that machete now) lol

worth trying, might actaully try this year!

Be very careful, with no place for air to escape, the sun will heat the air in there so quick it will completely cook your plant to a crisp within an hour.

With a couple air holes the same thing would happen, but youll have sometime to save it.

IMO, Use the bottle as a humidity dome before your seeds sprout but never put it over your growing seedlings.

works good for clones or seedlings

I have a 2-liter over a seedling indoors right now.

You can make a mini greenhouse out of pvc and clear heavy plastic (inthe rolls) . For instance, make asquare with the pvc and cut and tpe the plastic around. Then cut out a door to vent during day and close at night . Now you have a portable greenhouse you can move ( if you plant in pots) with the sun. Just a Thought. Good Luck.

you must have been pretty stoned when you thought of this. anyways not worth it in my view. your better off just putting some chicken wire aroung it or growing your plant in a dog cage.

True but a dog cage won't help with the cold weather. Look up home made greenhouse's. Maybe not worth it for you, but it might for him.

true that. well in that case i would just say make sure you cut holes in it so it doesnt suffocate.

i have used this method before and it does help with humidity and heat during the colder months but also can cook your plant if you not careful so leave the lid off and have the lid pointing up and then bury the bottom which will give a bit of air circulation or even have the lid section around the stem at the bottom??just a suggestion

I have used them before on all my gardening plants, the trick is to cut the right amount off of the bottle. Cut enough of so it doesn't overheat and not to much so it doesn't trap the heat at all. I have found that cutting enough off is so you end up with about an 1 1/2 to 1 3/4 diameter opening on top. Also using a grinder works better than a knife, but then I am a little accident prone. Good Luck Grow happy and have fun.
