WALL SPHERE TERRARIUM (easy, recycled, fast, cheap!)

Featured
(my inglish is weird today)
I made this really cool looking terrarium, you can hang it everywere. I made it all out of scraps, recicled wood, innertube, paint find in the street and recicled plaxiglass! I m going to make another one (with the pieces i m showing in the steps) for the shower! I will put plant of Potus, they really like umididity in teir air roots.
I find the dome of the main one in the street, and the one I show in the steps is given to me by a frend, it was his motorhome window.
You can find them in junkyards.
The globe need very little wather couse it keep the dirt from evaporated too much, so it really look cool but need very few care, if you choose the right plants.

1.make hole for screw together plywood and plexiglass: put plexiglass on plywood and hold it really firm , make hole in both at the same time.(put some tape on the plexiglass so drill don't slip)
2.make two holes in the plywood, the one for hang it on the wall, so they need to be big enough for BIG screw, that will be able to hold    it up.
3.make some hole in the bottom part of the globe, so that the water can drain out. (is not mandatory, you can also don't make any hole if you like your floor clean, just allowed the water to evaporated all from the bottom before watering it again).
4.make big hole (big enough to fit your hand in it and the plant, and allowed air in the terrarium) in the front middle part of the globe with the cutting bit.

This would look very nice with cacti in them. They need very little water to thrive. Have you thought of making a 3 litre soda bottle terranium?

Where did you find the plastic bubble ?

In the street, but you can find similar things in junk yards
This is neat - I've been looking for a terrarium for my room for some time now. I will have to look into this!!
Oh that's so neat. Reminds me of something you see on Startrek except it was filled with water and it had a lion fish in it.

Really cool terrarium. But doesn't the wood get moldy? I know you said you've had it for over a year already. Just everything I've ever known tells me wet wood should grow mold and mildew.
marcellahella (author)  Thrasym2 years ago
it doesent mold couse I ve covered it with few layer of watherproof house painting
(step 2)
Oh, sorry, I missed the waterproof detail on the paint.

That is a very nice looking Terrarium! I like the style.

You shouldn't need to add CO2 for several reasons:

1. Plants exhale O2 during the day, but they exhale CO2 at night. The exchange is somewhat weighted toward eventually using up the CO2 BUT

2. Unless you are trying VERY hard for a perfect seal, there is enough airflow to keep the plants healthy. Of more concern is dialing in the perfect amount of airflow to keep the humidity at a moderate level. Too wet will promote mold, too dry and the plants won't be happy.

The plants won't grow as fast as if they had a super abundant supply of CO2 BUT
3. You really don't want terrarium plants to grow fast. Most people grow terrariums for their extreme low maintenance, which means you won't want to be in there trimming all of the time.

Of course if you had some high humidity vegetables or herbs (not many out there) growing in a terrarium, then CO2 might increase your yield.

thank you! and you re right, i dont really want the plant becoming too giant too fast or I will have to cange terrarium soon!

I love this! Great job! I think the hole is just fine - you can add items (a pretty rock or shell that you find) and change things around if you like without taking it down. If you wanted to fill in the back hole, you could add a mirror.

thanks!
You should find a way to hook up a steady flow of CO2 so the plants will grow better. :]

I cant understand this CO2... why should i put it? there is a huge hole in the front of the plexiglass , you can see it if you look carefully...i have this terrarium for more than one year and the plant like it...
you could add the CO2 instead of having a big hole in the front. just for asthetics i guess.
marcellahella (author)  greenirishmoon2 years ago
yes, I will try it if is easy... but you still need the hole in the front to watering the plants, and clean them from dead leaves, or replace them... it doesent look too bad! but I will think about the CO2 things for the next one, thanks!

but there is 4 hole around the top and a huge one in the front...
