How are Jiffy's Indoor Seed Starting Greenhouses used? What makes them the best choice for starting your seeds indoors?

Is it that time of the gardening season again already?! As winter carries on and we begin to slowly approach the final frost dates for each growing zone throughout the United States, we are here to cover yet another *amazing* group of gardening accessories by Jiffy: Indoor Seed Starting Greenhouse Kits! These kits consist of miniature indoor greenhouses (22” x 11” x 3” at their largest) that you can use with your Jiffy Seed Starting Peat Pellets. You can also recycle the bottom tray and humidity dome to use these greenhouses with dirt and soil in the future, if you so choose. Determining how you use these items is a matter of preference which you can tailor to your liking and/or need!

Most Jiffy Professional Greenhouses will include peat pellets, one re-usable watertight plastic tray, one re-usable and/or recyclable plastic Gro-Dome and bonus items such as plant markers and SuperThrive. Other Jiffy Greenhouses will come with celled peat trays (peat pellets not included) and a humidity dome. Be sure to read the product details in order to confirm what is included with your Jiffy Professional Greenhouse.

    Every Jiffy Greenhouse will include instructions specific to the product you are using. These instructions are easy to follow and should act as a guideline when sowing your seeds inside the greenhouse. Typically, however, you will be instructed to:

    •  sow your seeds (in either peat pellets or soil)
    • add warm water (this may be your first step if you’re using peat pellets!)
    • apply the Gro-Dome cover (Gro-Dome = humidity dome)
    • place the greenhouse in a warm location away from direct sunlight

    Yes, it actually is as easy as that when you’re using Jiffy’s Greenhouse!

    Examples of the different types of Jiffy Seed Starting Indoor Greenhouses

    You might be thinking “Ok, now I know what kind of greenhouse options I have and how to use and assemble them…but what good are they to me?” Well, let us give you a quick rundown of what makes Jiffy’s Professional Greenhouses so great for indoor seed starting.

    For starters, they come with a reusable watertight tray. Keep your tray for seasons to come because it can be used multiple times AND it’s made from 100% recycled materials. Also, there’s that mention of watertight. That’s no exaggeration…greenhouse trays hold water so you don’t have to revisit watering your seeds as often as you’d think.

    Next, we have the greenhouse Gro-Dome which is plastic that can be reused or recycled! The Gro-Dome is a humidity dome locking in essential moisture and, once again, eliminating the need for frequent watering. The humid environment the greenhouse creates will aid in the germination of your seeds with little to no effort on your end.

    When first seeds have sprouted inside of your Jiffy Greenhouse you can simply prop the dome open. When all of your seeds have sprouted, you remove the Gro-Dome piece completely and place the tray in a sunny location until transplanting time!

    TL;DR Jiffy Greenhouses are miniature hothouses that mimic an environment which encourages seed germination with little to no effort on your end. Once the seeds have sprouted you can easily transplant them anywhere from your greenhouse!
