Have any of you ever planted a Wardian Case Terrarium? I have recently been very lucky to receive two of these and I have planted them about three weeks ago. The potting medium has stayed moist, but I don't see any condensation. I don't want to overwater them but I always thought that condensation was essential for the ecosystem in terrariums. Any advice on the subject would really be appreciated. Lou

Are they closed tightly? If there is any opening at all you will lose the condensation.
Condensation isn't always a good thing either...too much of it leads to mildewy plants. I ended up having to prop the lids open on all of my terrariums on account of this.
As long as the soil is moist it should be fine.

Thanks! They are both from estate sales and may not be air tight as they are designed to be. I will just continue to monitor them and see how long the soil stays moist without any additional watering. So far, the plants all look good and are growing. Lou

Just to add to Lee Anne's comment - just because there's no condensation, doesn't mean there isn't humidity.

I would love to see pictures of your cases, it sounds really interesting! What plants did you put in them?
In the end, only kindness matters.

Science is not the answer, it is the question.

Hi Lou, it's great to see you here at ATP! I'd love to see photo's of your Wardian Case's too! I've always wanted one but have so far just stuck with the glass jar terrariums and converted aquariums.

I agree with what has already been said. If the soil is staying moist and the plants seem to be adjusting, it sounds fine. Like Lee Anne, I've had a problem with too much condensation in my enclosed terrariums and end up having to remove the lids on occasion to allow for a little air circulation to dry them out or they end up with way too much moisture inside and plants begin to rot. You may notice more condensation in your Wardian Cases during the warmer months. Please keep us posted on how they are doing and share photo's if you can.
