Product Detail: Jiffy Tomato Greenhouse. It contains 36 peat pellets, a large plastic tray holds 36 pellets and a rectangle dome lid. The tray and lid act as the greenhouse. The peat bricks expand once soaked. You can find them at Walmart with various size options, from 25 to 70!
First, you need to submerge the peat pellets in water for about 30 minutes in a separate container and wait for them to expand. Be sure to check the water level often; before you know it the water will be absorbed and your little pellets will not have any water left to soak in.
Here are the ups and downs I've experienced with the mini greenhouse
- Easy to maintain while seeds are growing. The peat keeps moisture very easily, thus minimal watering.
- Peat keeps an optimum seed starting atmosphere.
- Easy to tell when watering is needed; the pellets will no longer be black but light brown.
- Minimal mess when planting. The peat does not get all over the place.
- No extra equipment needed, all is provided for you (except seeds and containers to soak bricks in).
- When you place the lid on top of container for multiple days, the water does not evaporate easily and it sits in container. Fungus will begin to build up on pellets, so frequent fungicide spraying is necessary. Another remedy is to let the green house sit open to air out for a few hours.
- Time consuming. Unlike other methods where you easily scoop soil into cartons, these take a while to prepare.
