How to Grow Cauliflower in a Greenhouse? Perfect Conditions All Year Round

Quick Answer:

How do you grow cauliflower in a greenhouse for perfect results year-round? Growing cauliflower in a greenhouse ensures consistent conditions—steady temperature, even moisture, and protection from extreme heat—leading to larger, sweeter, and more reliable harvests than outdoor crops. Start seeds indoors, stagger plantings to avoid a glut, and choose self-wrapping or colorful varieties like Veronica or Susanna for visual appeal and flavor. With drip irrigation, airflow, and soil amendments, your greenhouse can produce A+ cauliflower from spring through winter.

Lennie tracked me down at a party. “It’s my cauliflowers,” she sighed. “They are small and button-like instead of big like at the store.”

How Worm Castings, Pests, and Algae Affect Your Greenhouse Garden

Pests, Worm Castings and Algae

What are Worm Castings?

Before we get to greenhouse gardening algae, let's talk about a shopper on Amazon that complained about bugs in her worm castings. If you don’t speak garden lingo yet, worm castings are simply worm poop. They are mixed with soil in garden beds or in pots to make tomatoes grow faster, stronger and healthier. And just in case you missed the memo, worm poop comes with bugs of its own. The good ones.

Why is Aluminum the Better Choice for a Greenhouse?

Quick Answer:

Why is aluminum the better choice for a greenhouse? While aluminum does conduct cold, it outperforms wood in long-term durability, structural stability, and weather resistance, especially in cold climates. Unlike wood, which warps, rots, and requires ongoing maintenance like sealing, staining, and pest control, aluminum frames remain strong and low-maintenance for decades—even under snow loads and high winds. As lumber costs rise and customers seek reliability, aluminum has become the superior greenhouse frame material, with BC Greenhouse Builders offering proven performance and lifetime warranties on structures lasting 30 to 40+ years.

The Heinen Greenhouse Legacy Expands to the Okanagan

Wayne Heinen, the owner of Everlast Greenhouses, is the exclusive representative for BC Greenhouse Builders in the Okanagan and Kootenay region. 

Recently I had the opportunity to sit down and talk with Wayne Heinen, owner of Everlast Greenhouses.  To say that Wayne grew up around greenhouses is an understatement.  Wayne, the youngest son of Henry and Greta Heinen, started hanging around BC Greenhouses and pitching in building cedar benches at nine years old.

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.


Before You Order Seeds for Your Hobby Greenhouse, Read the Fine Print

 

When I started growing in my Greenhouse Garden a few of my favourite plants stopped working for me. That's what I learned to read the catalog fine print and adapt my shopping for a better hobby greenhouse growing. 

What's Everything I Need to Know When Preparing a Greenhouse Foundation?

Quick Answer:

What do I need to know when preparing a greenhouse foundation? Every greenhouse needs a solid, level foundation—typically wood or concrete—built to exact dimensions for proper fit, stability, drainage, and long-term success. Why is foundation planning essential for greenhouse performance and longevity? A well-prepared foundation supports structural integrity, ensures easy access to utilities, accommodates local conditions like slope or shade, and sets the stage for efficient growing and maintenance.


Do all greenhouses require foundation?

The simple answer is YES

Over the years we have had hundreds of greenhouse-related questions and many of them are related to foundations.

What Are the Secrets to Testing Old Seeds and Growing Golden Sesame Seeds?

Quick Answer:

What Are the Secrets to Testing Old Seeds and Growing Golden Sesame Seeds?
To test if old seeds are viable, place ten seeds on a moist paper towel in a ziplock bag and check for sprouting within a few days—this simple germination test helps gardeners save money and plan better. Golden sesame thrives in heat and drought, making it an ideal crop to start in a greenhouse and transplant outdoors for a high-yield harvest. Open-pollinated sesame allows for seed saving, extending your harvests year after year while maximizing greenhouse potential in any season.


A new crop, discovered in a seed catalogue last year, piqued my growing interest. I grow lots of vegetables but growing Sesame seeds didn’t occur to me until I saw them listed. I'm excited to try something new I ordered it right away.

 

What's the Best Soil for Greenhouse Gardening? A Comprehensive Guide

What is the Best Soil for Greenhouse Growing?

Quick Answer:

What is the best soil for greenhouse gardening? The ideal soil for greenhouse growing balances drainage, nutrient retention, and microbial activity—making custom blends like loam, triple mix, or super soil more effective than natural or bagged top soils. Should you use bagged soil or soil-less mixes in a greenhouse? While convenient, most bagged top soils and soil-less mixes lack essential nutrients and structure for long-term crops, so combining them with compost or organic amendments is key. How can you create high-performance soil for greenhouse plants? Blending your own triple mix (one-third soil, compost, and peat) or upgrading to a nutrient-rich super soil with worm castings, biochar, and trace minerals provides a strong foundation for healthier plants, richer flavors, and vibrant blooms.


If you are new to gardening and think growing is just a matter of adding water, you're in for a surprise. With terms like super soil, triple mix, natural soil, and even soil with no soil—it's no wonder new gardeners feel overwhelemed. So how do you choose the right soil for strong, healthy growth? And how do you get the most flavorful food and the brightest blooms?
