Seed-Starting Terrarium, Part 2

Spring is certainly taking its time out here in Lancaster, PA. The temperatures at night still dip below freezing, and even the robins are shy to come out from hiding. But I’m not going to let a silly thing like the weather hold me back from starting my fun in the sun.

Last month I whipped up a little seed-starting terrarium to get a head-start on spring. The best place for growing things indoors is typically any south-facing window, but all of ours have a tree right in front of them. The next best thing for us was a window in our dining room, which unfortunately wasn’t good enough. Only one tomato seed managed to germinate in the few weeks that it sat by the window, and the way this little seedling stretched his neck up to the glass I could only surmise that it wasn’t getting enough sunlight.

I could have put a little lamp overhead, but by this time the weather was cooperating enough for me to place the terrarium outside in the real sun. Before I did so, I wanted to build out the glass into a dome. I found a couple of old windows and ripped two two-pane sections off with the table saw for the sides. This worked great except that they weren’t quite long enough. In order to complete the dome I had to carefully remove a few pains and use a glass cutter to resize them. Then I built a simple frame for each new pane. A little bit of fun with the nail gun and all done.

Now that my terrarium is getting lots of sun, my seedling is growing strong. In the day I keep the top pane open slightly to allow for ventilation, but even so I’ve got a warm and cozy little environment for my seedlings to do their germination thing.

I added a few more seeds now that I have a little more room. I’ve been craving fresh basil for a while now, so I planted the basil seeds that I had saved. I also planted some more patio tomatoes and bell peppers that will go up on the roof in their self-watering containers when the weather allows it.

Spring may be a little shy this year, but not totally forgotten. Even last year’s thyme is starting to perk up, and the lungwort has already flowered. It won’t be long now until the roof garden is in full force. To think that soon I’ll be battling the heat of summer instead of the chill of winter only encourages my industrious side. Come on, little seedlings, time to grow up before summer is here!
