Step 5: Use it

Picture of Use it
Now all you have to do is fill the cup with soil and seeds (or small plants), put the base on it, then put the lightbulb over it.
Place it in a well lit window sill and occasionally water it

very nice
what do you do if the plant gets too big for the light bulb? can you just leave it or do you have to replant it?

I want one! They look awesome... I actually did a photoshop thing for a "be green" poster in high school with the same concept. I'll have to bookmark this and come back to it if I ever find myself at my parents' house without my kid... newborns and breaking glass don't mix very well, lol

I just wanted to make a comment for those people who think the plant needs air holes.  I have made several stained glass terrariums that use this same principle.  If you give the plants an airtight house, you create a mini ecosystem and the water that's inside will eventually evaporate to the top, condensate on the glass, and fall back down like rain.  It will keep doing that over and over, and you end up hardly ever having to water (and when you do, I guess you get some new air in).  I have one going that I started years ago.  I water every couple of months because it's not completely airtight and eventually some water does escape by evaporation.  A few plants have died (some work better than others in these situations- and I've also let it get a bit too dry at times- completely forgetting about it since you normally don't have to water it).  I still have a couple of the original plants, though...
Maybe this calls for an instructable.  I've never made one. :)

This is very interesting. And it triggered an idea ...
We have a deserted aquarium in the attic. I thought maybe I can make a bigger greenhouse with a wooden box filled with soil and plant seeds, and the empty tank placed bottom-up on it:

Cute. I can't wait to see you make one out of a flourescent lightbulb after LEDs take over.
Fluorescent bulbs contain mercury and lead powder.

how do you water the plant?
stryke2976 years ago
How exactly does this plant grow? It looks like it's in a sealed container which kinda sorta stops one half of the respiration process, and wouldn't you think it would get very hot inside that lightbulb?
thats what plants like(warmth) so if you you water it regually it won't dry out and it will grow well thats what a greenhouse does.
gr8 man!

i rekon its really cool and i might try it but once the plant gets too big how do you squeeze it through the light bulb bit or do you just smash the whole thing and how do you water it

I grew mint, so size wasn't an issue. You water the cup by tipping the top part up.
Thats a very nice idea. I'm trying do grow a little tree in it. Perhaps it will work. First i tried to drill some little holes into the bulb, so the tree can get air, but i don't recommend it. the bulb is broken and my finger has one scare more.

Thanks. Keep me posted if you are successful. You could try heating the bulb with a blowtorch and poking them out.

That tree will live during one week. I think so. You should continue to bring many things into play. Goodluck!!!!!!

I've managed to keep it alive for 2 months. Thanks

I think this is has a very beautiful result, but I have my doubts about the results, because the plant need to breath. Maybe with some small holes in the base of the lamp...

This is really cool, but dont most plants need CO2 to survive? Doesnt seem like it could get much if its incased in a light bulb. Is the plant still alive?

Looks nice, might try it :)

Thanks! post pictures if you do
Ok, but first, a broken lightbulb, to bad we mainly other lights... but i'll ask if next time my sisters lamp broke up she can get a lightbulb ;-)
im gonna do this ill try and post pics :P

Good job, interesting idea!! Do you have any photos of what happens after a few weeks? When the plant grows?
