Greenhouse Hack for Starting Seeds for Your Garden
Build a Miniature Greenhouse Using an Everyday Item
I love using basic things in my home to accomplish what I need to complete a project. I'm at a time in my life where I am giving no longer needed items to my grown kids to declutter and simplify my home.
For the purpose of starting seeds to plant in my garden or in decorative pots, I was looking around for ideas to create a repurposed or reusable container. I've found it and would like to share with you how I'm using a underbed or gift wrap roll storage container, regular gardening items, and basic household and kitchen accessories to create my mini-greenhouse setup.
Seed Starting for my Flower Garden
Supplies Needed for Your Mini-Greenhouse
How to Set Up a Tabletop DIY Greenhouse
- Open storage container upside down or place the separated top on the surface.
- Try arranging trays to fit. Cut and remove some cells to fit if needed.
- Fill cells with soil. Tamp down and water until wet. Top off with more soil if needed and repeat watering. If soil or seed starter seems to float, I may leave until the next day and re-dampen the medium.
- Plant seeds according to packets. Mark rows or individual cells if more than one type of seed is planted. A few marking ideas are shown below.
- Add water to the tray so that it is at least 1/8" deep. It's important for seeds to stay wet instead of just damp for the first 24 hours to kick-start the rooting process. This also helps with many coated seeds.
- Cover, and proceed to "Quick Sprouting" below.
Suggested Tools You May Already Have for Tending Your Garden Transplants
My Green Reusable Tools List
- Spray bottle formerly contained hairspray
- Plastic fork perfect size for digging in small cell seeding tray
- A Plastic knife for tamping new plantings
- Plastic knives are also good for labeling rows
- Outside thermometer for checking temperature, and humidity if available
- Tweezers or forceps (see Forceps in the bowl above)
- Plastic smooth bottom bowl for selecting seeds for sowing
- Small funnel for pouring seeds and returning unused seeds to packet.

How to "Quick Sprout" Seeds
- Heating pad
- 2 Towels
- and your covered mini greenhouse
- Place towel on tabletop or other desired location
- Place greenhouse on top
- Place heating pad on top greenhouse
- Place other towel over heating pad entirely covering greenhouse
- Set heating pad on lowest setting.
- Leave covered and heating for 3 days.
It really doesn't make sense that this supercharges seeds, but it does work for many plants.
This process does take a little follow-up to acclimate. For the first day, I suggest removing cover and heating pad to allow your new seedlings to adjust to the light. The second day, check for moisture and add water if needed. Then open the cover during daylight hours. Return to the regular schedule.

Watering Maintenance for Your New Greenhouse Plants
Test the moisture in the tray cells. If a finger pressed on the soil is:
- Slightly damp, it's good
- Dry, water it
- Wet, drain tray if needed, and leave the top off to dry a bit ~or~ place outdoors in temperate weather
Nighttime Schedule for Maintaining Greenhouse Seedlings
- Indoors: At night, if indoor temperatures are expected to be less than 65-70 degrees, place heating pad set on the lowest temperature and cover with a towel. If temperatures are expected to between 65-70 just close cover and skip heating pad, but cover with a towel. Real plants appreciate evening darkness, too.
- Outdoors: If you expect the temperature to be at least 65 degrees, your plants will love having a night out, but won't appreciate the stress of heavy due or rain yet due to immature fraility.
How to Maintain a Mini Greenhouse During Daytime Hours
During the day, if outdoor temperatures are expected to be above 60 and partly sunny, feel free to take your greenhouse outside, flip off the top, and let your little garden seedlings enjoy the natural sunshine. They will also appreciate windy breezes which makes their stalks stronger. If all day sun or higher temperatures are expected, try to find a place that will give some shade in the afternoon. New little plants will overcome heat wilting and sunburn, but those incidents will delay the process since recovery does make the plants work harder to fix themselves instead of growing.
Return to the house in the evening for temperatures below 65, and follow the nighttime process.
