Have you been considering adding microgreens to your homestead, but feel completely mystified by the actual day-to-day process?

Maybe you are looking for a reliable side hustle that brings in extra money without swallowing up your precious family time, or perhaps you want to add a high-margin offer to your existing CSA or farm stand?

When you look at commercial setups online, it is easy to assume you need complex warehouse systems, expensive specialized trays, and endless hours of tedious labor.

I am here to tell you that you do not!

As a homesteading, homeschooling mum running an off-grid market garden with my husband, my days are already packed tightly.

Between lessons, kids, animals, and managing our main greenhouse crops, every single project we take on has to earn its keep and fit into our life on the land.

When we started out, we grew everything we possibly could in our greenhouses. But, we quickly learned a hard lesson: just because you can grow something well does not mean it sells well, or that people actually want it.

That is where microgreens completely changed the game for us. Alongside our cut salad mix, microgreens have become one of our most fundamental, profitable parts of our business.

We supply residential customers (through weekly orders and our farmstand), local cafes, and restaurants. They love them because they are incredibly nutrient-dense, and they instantly elevate a simple meal like eggs on toast or a salmon bagel to look a million dollars.

If you are an off-grid homesteader looking for a reliable side hustle, or a grower wanting to add high-margin value to your existing offer, microgreens are a perfect fit.

The best part? You do not need expensive commercial gear, and the active working time fits easily around a busy family schedule.

Here is exactly how I manage the production cycle in less than an hour of hands-on time most days, right from home.

Sprouts vs. Microgreens: What Are We Actually Growing?

Before looking at the routine, it helps to understand what makes these a premium crop. Microgreens are not the same as sprouts.

With sprouts, you rinse seeds in a jar and eat the entire sprouted root, seed, and shoot before any leaves form.

Microgreens are sown onto a growing medium. You grow them until their very first leaves – called cotyledons – appear. Then, you cut them just above the soil line, leaving the roots behind.

We tried various mediums like coco coir and mats, but we found they were expensive and gave poor yields. Instead, we use a high-quality, fluffy, airy potting mix (not a heavy outdoor veggie mix with big chunks of organic matter).

This gives us the best yield, and the spent soil goes straight into our compost pile or around our plants as mulch for a second use.

We have dialed our production down to three superstar varieties that are straightforward to grow, yield heavily, and fly off the shelves:

• Pea Tendrils: Extremely popular with restaurants for their beautiful frills.
• Sunflower Shoots: Thick, crunchy, juicy, and add great texture to salads.
• Purple Radish: Adds a fast, spicy, mustard-like kick and a vibrant pop of colour.

Our Frugal, Off-Grid Setup

We started our business very frugally, off the smell of an oily rag.

Commercial microgreen trays are expensive and often too deep, meaning you waste a small fortune filling them with soil.

Instead, we bought plastic café dinner trays measuring 32cm x 42cm (about 12.5 inches x 16.5 inches). This gives a very similar surface production area to the popular commercial 1020 trays (10 inches x 20 inches) you see online.

We drilled drainage holes into half of them. Each setup uses two trays: one with holes packed with less than half an inch (around 10mm / 0.4 inches) of potting mix, sitting inside a solid tray to catch water and allow for bottom watering.

Because we are off the grid, we have to balance our power usage carefully.

We use standard hardware store racking placed right in front of a massive glass stacker door to maximize free, natural sunlight. To help them along, we use low-draw T8 LED bar lights hooked up to a timer that only turns on during peak solar production hours.

For airflow – which is vital to prevent mold – we clip small, low-power USB desk fans right onto the shelving, above the microgreen trays.

The Weekly Routine: Step-by-Step

In the summer, the turnaround from seed to harvest takes 7-8 days. In the cooler winter months, the cycle slows down to at least a week and a half (10 to 14 days).

To ensure uniform, rapid growth, you want your indoor germination and growing space to hold a steady temperature range between 18°C and 24°C (64°F to 75°F).

Here is how the days look:

Day 1: The Five-Minute Soak

I start this step around 9:00 AM on a Thursday or Friday – working back from when they’re needed for selling.

I measure out exactly 1 cup of unsoaked pea seeds and 1 cup of unsoaked sunflower seeds per tray.

• The Action: Put the peas and sunflowers into separate tubs and fully submerge them in cold, fresh water. This hydrates the seeds and softens the tough outer shells.
• The Routine: This takes five minutes. I set a timer for 8 hours and go about my usual daily duties, homeschooling and homesteading. At 5:00 PM, I drain the water, give them a quick rinse, and leave them damp in their tubs overnight.

Day 2: Planting, Misting, and Weighting

This is the main planting day, taking around an hour even when managing up to 20 trays.

• The Soil Prep: I fill the drilled dinner trays with 10mm (0.4 inches) of fluffy potting mix, then use an empty tray to lightly press down, creating a perfectly flat surface. Crucially, I water the medium well at this stage so the soil is deeply damp before any seeds are added. This locks in the baseline moisture needed for strong germination.
• The Sowing: I spread the soaked peas and sunflowers evenly across their respective trays, making sure they sit in a single, snug layer. For the purple radish, seeds do not get soaked ahead of time; instead, I sprinkle exactly 40g (about 1.4 ounces) of dry radish seed evenly across the damp soil.
• The Secret Mold Weapon: Before stacking, I give the sunflower seeds a light misting with a highly diluted (3%) hydrogen peroxide solution (H2O2). It sounds scary, but H2O2 is just water with an extra oxygen molecule, and can be purchased at most pharmacies or chemical supplies. The mist fizzes gently on contact, destroying bacteria and pathogens, which has drastically reduced our mold issues. The radishes get a light mist of plain water to lock in their surface hydration.
• The Weight Setup: Stack the planted trays directly on top of one another (no more than 5 or 6 high, or they tip). Place a wooden board across the top tray, and load it down with two 5kg (11 pound) lifting weights. Weighting them forces the roots deep into the soil and creates incredibly strong, uniform shoots.
• The Routine: Place the stack somewhere warm and safe within that 18°C–24°C (64°F–75°F) window to germinate.

Days 3 & 4: Left Alone

The trays stay stacked under the weights. Because the soil was properly dampened before sowing, the seeds have all the moisture they need. You do not need to touch them.

Day 5: Uncovering and Flipping

By Day 5, the germinating seeds are actively pushing up against the 10kg (22 pound) weights.

• The Action: Unstack the trays. Give them a thorough, good watering using a garden hose nozzle set to a gentle shower setting. You are not looking to completely flood or pool the soil, but a single, solid shower pass ensures they are well hydrated as they enter the light.
• The Blackout Trick: Move the trays to your racking system. Take an empty dinner tray, flip it upside down, and place it over the growing tray like a dome. This keeps the environment moist and dark. Because the shoots are searching for light, this dome forces them to stretch upwards, creating longer stems and a much higher harvest yield.

Days 6 & 7: The Stretch and Bottom Water

Keep the trays covered with the upside-down domes for another 2 to 3 days.

• The Action: Every morning, check the soil. If it feels a bit dry, pour water directly into the bottom, solid tray so the roots can drink from below, keeping the leaves dry and mold-free. This takes about 5 to 10 minutes total.
• Seasonal Adjustments: Over the winter, they need about half a cup to one cup (120ml to 240ml) of water. Over the summer, they drink heavily and require up to two cups (475ml) of water. Take extra care if the sun is shining brightly through your windows; they can dry out completely by the afternoon if you do not catch them early.
• Seed Hull Brushing: For the sunflowers, the humidity under the dome keeps the seed hulls soft. Run your hand lightly across the top of the shoots to help brush off the hulls so the leaves can pop free.

Days 8 to 14: Light and Harvest

Once the microgreens are at least 6cm (about 2.5 to 3 inches) tall, remove the top dome entirely and let them sit under the lights and sunlight for about 2 days to green up. Longer in wintertime.

You want to harvest them before the true leaves show. For sunflowers and radish, you only want the smooth, first leaves; if the jagged, fuzzy true leaves develop, the texture gets unappealing and the taste changes. For peas, you want to wait until the frilly tendrils are nicely formed.

• The Harvest Action: I clear off my kitchen bench to create a clean, sterile environment. Using a very sharp knife, I grab a handful of the greens and cleanly slice through the stems. For peas, make sure to cut well above the soil line – the very bottom of the stem is white, stringy, and too chewy for customers.
• The Routine: Cutting takes a couple of hours depending on how many trays we have. Because it is safe and low-input, I sit at the bench and do this while my kids are nearby doing their schooling, chores, or chatting. If I’m lucky. I get to enjoy a favourite podcast in peace! It fits beautifully into our family life.

Once cut, I lay them out on a clean cloth to grade them, flicking off any stray sunflower hulls before packaging.
