Quick Answer:

Start tomato seeds in mid to late March with bottom heat, provide strong light and nutrients early, and move them into your greenhouse once temperatures consistently stay above 10°C (50°F); maintain airflow and prune lower leaves as fruit sets to optimize harvest into fall.

So Many Tomatoes, So Little Space

Greenhouse tomato growers are rightfully confused when they see so many kinds of greenhouse tomatoes for sale. Karen Olivier, an independent tomato breeder from the Secret Seed Cartel, estimates there are 20,000 kinds of tomatoes listed right now and she is adding to that number by breeding new tomatoes every year.

 

A Testament to the Durability of BC Greenhouse Builders Products

Big thanks to Larry Clarkson for telling us the story of his two used Traditional Greenhouses

Larry won the greenhouse lottery and found two used BC Greenhouse Traditional model greenhouses on, of all places, Craigslist. It's worth saying that we do not sell used greenhouses. After this story broke, our email blew up with requests from customers wanting to buy refurbished greenhouses. 

As with any company, there are many people, vendors, and supporters that make up the fabric of your success.  When I started at BC Greenhouse 10 years ago, they shared with me the story of Erik Davis and it was a pleasure to talk with Russ and Aarron Davis to get the full history of our Vancouver Island connection.  It’s clear that Erik Davis was one of the remarkable people that changed the course of our company.  Erik was a bricklayer by trade who lived on the Island and he was known for his love of gardening. The president of four garden clubs, Erik was familiar with BC Greenhouses and had met Don Vale who was an installer with BCG.  Erik purchased his first greenhouse in 1981.

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 Best Tips for Soil Amendments & Nutrients in a Greenhouse Garden?
Optimizing greenhouse soil requires building “super soil” by blending quality soil-less mix with compost, biochar, and worm castings, plus adding essential nutrients like nitrogen, phosphorus, potassium, calcium, and micronutrients through amendments such as seed meals, lime, kelp, and gypsum. Recognizing nutrient deficiency signs—like purple leaves from low phosphorus or brown spots from potassium shortage—helps timely fertilization and soil management, ensuring healthy plant growth and improved crop flavor. Regular soil amendment and fertilization tailored to plant needs foster vibrant, productive greenhouse gardens year-round.

Importance of Soil Amendments & Nutrients in Greenhouse Gardening

A few years back my greenhouse tomato leaves were purple, yellow and spotted. Not all at once, but over time and on different leaves. It was the second year I was growing in my greenhouse and the commercial potting soil I bought was low on phosphorus, nitrogen and potassium. The leaves on the plants were telling me what was going on. And it didn’t look good.

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. 

Previously, I put out a request for stories and projects that helped to shape the BC Greenhouse that we are today. Rick visited my office and mentioned the WindSong Cohousing project.  I had never heard of this project and ironically Cody found newspaper articles and stories about WindSong and left them on my desk this morning. I love how the universe works.
