How I’m Growing Greens All Year Round

How I’m Growing Greens All Year Round: My Hydroponics, Hoop House & Hot Bed Adventure

Introduction

I never expected to find a pocket of warmth hiding in my garden in the dead of winter—until I stumbled upon a steaming vermicompost bin on a cold morning. The outside temperature was well below freezing, but there it was: a cozy pile of compost giving off enough heat to keep the worms thriving. That serendipitous discovery led me down a rabbit hole of research, ultimately introducing me to hot bed gardening. Today, I want to share how I’m transforming my backyard into a year-round garden by combining hydroponics, a hoop house, and good old-fashioned compost heat.

Why Year-Round Gardening Matters

I love gardening for so many reasons: fresh produce, mental relaxation, and the chance to connect with nature. But every winter, my outdoor plots would grow silent, leaving me with wilted herbs and empty raised beds. I realized I wanted a constant supply of homegrown greens, no matter the season—so I started looking into ways to extend the growing period and reduce reliance on grocery stores. A year-round setup not only keeps the harvest flowing but also cuts down on the carbon footprint of out-of-season produce shipped from across the globe.

My Three-Part System

This year, I’ll be experimenting with three key components: hydroponics, a hoop house, and hot bed gardening. Here’s a quick breakdown of how they work together:

1. Hydroponics

   • Ideal for indoor or controlled environments—just water, nutrients, and a growing medium (like coconut coir or rockwool).
   • No soil needed, so you can grow leafy greens (like lettuce, kale, or basil) in a smaller footprint.
   • Fits perfectly in a spare corner of the basement or a sunny room.
   • Outdoor hydroponic systems can extend your growing season using flowing water or rafts.

2. Hoop House

   • Essentially a mini greenhouse made of PVC or metal hoops draped with plastic sheeting.
   • Retains heat and humidity, extending your growing season several weeks in both spring and fall.
   • Easy to build and relatively budget-friendly.
   • Allows you to start your seeds earlier, harden as you go, and keep plants alive longer into the winter.

3. Hot Bed Gardening

   • Uses the natural heat from compost (like a vermicompost bin) buried beneath your garden bed.
   • The decomposition process gives off warmth, keeping soil temperatures higher even in chilly weather.
   • A great way to keep root crops and cold-hardy greens alive through winter or jumpstart early spring plantings.

My “Aha!” Moment: Warmth from the Worms

Let’s circle back to that moment I discovered my vermicompost bin radiating heat. It was a freezing November day, and I’d gone outside to dump kitchen scraps. I lifted the lid, expecting to find a brick of frozen compost, but instead I found steam rising from the worm castings and more activity than I had seen since Spring. Intrigued, I stuck my hand in—some might call me brave or foolish—and was shocked at how cozy it felt. I realized, “Hey, if this compost is warm enough to thaw my fingers, it can probably heat a garden bed too.” That’s when I did some digging and learned about hot bed gardening, an age-old technique that harnesses the heat from digestive fermentation processes during decomposition. Dr. Elaine Ingham, a renowned soil scientist, refers to this process as the microbes “cooking” the compost by "getting it on!"

Setting Up a Hot Bed

I decided to try hot bed gardening under my hoop house to keep the environment extra toasty. Here’s a simplified version of what I did:

1. Prepare a Site

   • I dug a shallow pit and lay down a base of “brown” compost material (you can use straw or leaves, I used paper bags and cardboard boxes).

2. Layer the Compost

   • I spread a healthy mix of chicken manure and fresh kitchen scraps.
   • Kept it moist but not soggy—this balance helps microorganisms do their job efficiently.

3. Top It Off

   • I covered the brown/green layers with a few inches of light and fluffy vermicompost as a growing medium for my seeds.
   • Added my trusty row cover or hoop house above for insulation.

As the compost decomposes, it releases heat, gently warming the soil from below. You're looking for a nitrogen rich compostable to mix with equal to greater amounts of brown material in order to draw out the fermentation process for weeks to months. Meanwhile, the hoop house keeps out harsh winds and traps warm air. The result is a cozy environment for cold-tolerant veggies like spinach, lettuce, beets, celery, and carrots—even when outside temperatures dip below freezing. When I'm ready for another cycle, I'll have an abundance of compost to use for the next batch.

Looking Ahead: Dreams of Year-Round Abundance

With my hydroponic system humming away indoors, a hoop house sheltering tender greens, and a hot bed fueled by my compost, I’m finally inching toward that year-round harvest I’ve always dreamed of. Next, I might experiment with solar-powered heat mats or even incorporate automated IoT sensors to track temperature and humidity (I can’t resist). Ultimately, the goal is to sustainably produce nutritious food, improve the soil, stay connected to the earth, and have a little fun along the way.

Conclusion: Give It a Try!

If you’re curious about extending your growing season or just love hands-on gardening experiments, give hydroponics, hoop houses, or hot bed gardening a shot. You don’t need a massive backyard—creativity and resourcefulness go a long way. Start small, see what works, and don’t be afraid to learn from missteps. I’ve found my winter gardening journey both fascinating and fulfilling, and I hope you will too!
