Hi, Keyring - I've been at DG since 2001, but am new to terrariums. I look forward to digging into this forum for ideas. Our house is small and I have no dedicated space for growing right now, but little plantings like this I know I can manage. =)
Cool. I do have a 20gallon fish tank I could make into a terrarium; it has a lid with a light I could replace with a plant light. It could go beneath my 55-gallon aquarium on the bottom shelf of the stand.
Where is the jar that the little sweetie pie Sinningia White Sprite is growing in placed in your home? How much light does it get during the day and what is the exposure please? Do you have screens on your windows? I know this sounds like a silly question but we leave our screens up year round now to reduce bird collisions and that is about the equivalent of 30% shade cloth.
this one was kept under fluorescent tubes (T12s). I had the same plant a foot from a lightly tinted SE facing office window, with a row of slightly taller plants between the window and it. It got some "direct" sun for a short part of the day, and shade for the rest. It seemed to be about the right amount of light.
There is, of course, a lot more algae growth with sun. Also, if you have too much sun, you will steam the plants - temps can go high very quickly. Worth putting a min/max thermometer in there if you're not sure.
Ok, so this plant might be able to survive nicely in a window with a screen. That's encouraging.
I do have a problem with algae growth in this home. I have tried growing pinguicula in pure LFS and always end up with green sludge in no time at all. I've had somewhat better luck with New Zealand Long Fibred Sphagnum Moss but not that much better.
Can I use a floating fish thermometer to check the temps? I pick those up at WalMart real cheap and they seem to measure the temps of any medium to within a degree or so of actual temps. Is it the actual air temps I am to measure because if so, I could place a regular room thermometer in there.
I've been thinking about buying a couple of mini type AV's or other plants for a glass jar or two that I have sitting empty. I wondered about having a lid on it, like a small terrarium. Will have to contemplate what I'm gonna do.
