What Are the Tips for Ordering Seeds and Supplies? Hobby Greenhouse Growing

Quick Answer:

What are the tips for ordering seeds and supplies for hobby greenhouse growing? To succeed in hobby greenhouse gardening, it’s crucial to read seed catalog fine print carefully—choosing parthenocarpic varieties for cucumbers and zucchinis that don’t require pollination, selecting heat-tolerant and slow-bolting plant varieties, and using foliar fertilizers for cold soils. Understanding pollination needs, temperature tolerance, and plant growth habits ensures better yields and healthier crops year-round. Starting seeds indoors, like onions in January, and adapting to your greenhouse environment helps optimize growth and harvest success.

How Much Food Can My Small Greenhouse Grow?

Quick Answer:

How Much Food Can My Small Greenhouse Grow?
A small 8’ x 8’ greenhouse can produce a surprisingly abundant and diverse harvest by maximizing vertical and horizontal space with crops like microgreens, radishes, lettuce, tomatoes, and cucumbers, especially when supplemented with seasonal heating and grow lights. Crop selection and greenhouse heating significantly impact yield and growing seasons, allowing multiple successive harvests and year-round gardening possibilities. To optimize food production, gardeners should prioritize fast-maturing crops they love and efficiently use all growing areas, including shelves, pots, and hanging baskets.


We get asked regularly "how much food can I grow in one of your smaller greenhouses?" 

Why Should I Start My Fall Crops Now? Take Advantage of August's Greenhouse Space

Quick Answer:

Why Should I Start My Fall Crops Now?
Starting fall crops in August maximizes your greenhouse space by replacing summer plants like zucchini or lettuce with fast-growing cool-season crops such as radish, kale, peas, and spinach. This strategic transition extends your harvest into fall and winter while allowing you to propagate strawberries, collect seeds, and prepare transplants. By planning now, you create a continuous cycle of fresh food, making your greenhouse more productive year-round.


August Plants

August crops are growing so fast that I should have a time-lapse camera to record the speedy growth. It’s a good thing I’m home all month to watch the changes and get the next crops planted and growing.  Check out my tips to grow your own food too!

Should I Buy Shade Cloth This Summer? A Greenhouse Gardening Must-Have

Quick Answer:

Should I Buy Shade Cloth This Summer?
Yes—installing shade cloth is a game-changing upgrade that instantly lowers greenhouse temperatures, prevents plant stress, and transforms your space into a productive and enjoyable retreat during hot weather. Shade cloth improves plant health, reduces cooling system strain, and can make your greenhouse a cool midday escape—even at 30°C. Choose 47–70% shade depending on your glazing and exposure, and install before summer heat peaks for optimal results.


Hot Summer Gardening

I had to take a break in the shade. It was over 30 C, the sun was beating down and I was thinking I might be getting heat stroke. So I stepped into my greenhouse to cool down.
