I want to tell you something that took me an embarrassingly long time to figure out.The freshest, most nutrient-packed microgreens I’ve ever put in a recipe didn’t come from a farmers market, a specialty grocery store, or an expensive delivery service. They came from a shallow tray sitting on my kitchen windowsill, next to a half-drunk cup of coffee and a stack of cookbooks I keep meaning to reorganise.Growing microgreens at home is genuinely one of the easiest things you can do in a kitchen. No garden. No outdoor space. No experience with plants whatsoever. Just a tray, some seeds, water, and about ten days of patience.Once I cracked it, everything changed. I had fresh microgreens available every single week — for smoothies, salads, sandwiches, avocado toast — for a fraction of what I was spending at the store. And honestly? Homegrown microgreens taste noticeably better. Crisper, more vivid, more flavourful. There’s no comparison.This guide covers everything you need to start your first tray today, even if you’ve killed every plant you’ve ever owned. What Exactly Are Microgreens? Before we get into the how, it helps to understand the what — because microgreens are often confused with sprouts, and they’re genuinely different things. Microgreens are the seedling stage of vegetables and herbs, harvested 7 to 14 days after germination, once the first true leaves have appeared. They grow in a growing medium (soil or a hydroponic mat), they’re snipped above the soil line, and you eat just the stems and leaves. Sprouts, by contrast, are germinated seeds eaten root and all, usually grown in just water with no growing medium at all. They’re harvested even earlier — often within 3 to 5 days.The distinction matters because microgreens are significantly safer (less risk of bacterial contamination than sprouts), more versatile in cooking, and produce a far better texture for everything from salad toppings to smoothie ingredients. Popular varieties include sunflower, pea shoots, broccoli, radish, arugula, beet, kale, basil, and amaranth. Each has its own flavour profile, growing time, and best culinary use. We’ll cover that in detail below. Why Grow Your Own? (The Real Maths) Here’s the number that convinced me to start: A 50g punnet of microgreens at a well-stocked supermarket typically costs between $4 and $8. That’s one serving for a salad, or maybe two smoothies. A bag of sunflower microgreen seeds — enough to grow 8 to 10 trays — costs about $6 to $10.If you harvest once every 10 days, that’s roughly 36 harvests per year from a single bag of seeds. At store prices, you’d spend $144 to $288 per year on the same amount of microgreens. The seeds cost you $10.The maths isn’t subtle. Home growing pays for itself in the first month. Beyond cost, there’s the quality argument. Supermarket microgreens are cut up to a week before you buy them, then sit in refrigerated transport and storage. Homegrown microgreens are cut minutes before you eat them. That difference in freshness is genuinely visible — in colour, in crunch, and in taste. What You’ll Need (The Complete Beginner Kit) The good news: you don’t need much. Here’s the full list:The Essentials 1. A shallow growing tray Standard 10×20 inch seedling trays work perfectly. You want something about 1 to 2 inches deep with drainage holes. Reusable plastic trays are ideal — they last for dozens of grows if you clean them properly between batches. Alternatively, repurposed takeout containers with a few holes punched in the bottom work completely fine. 2. A second tray (no holes) for bottom watering More on this in the watering section — but having a solid tray underneath your draining tray is the method that will give you the best, most even growth. 3. A growing medium You have two main options:Potting mix or seed-starting soil — the easiest for beginners. Use a fine, well-draining mix. Avoid anything with large bark chips or heavy compost.Hemp or coco coir mats — a cleaner, soilless option that sits flat in the tray and requires no potting mess. Slightly more expensive but reusable and mess-free. 4. Seeds This is the most important variable. Buy seeds specifically sold for microgreens — not regular garden seeds, and never treated or coated seeds. Microgreen seeds are sold in larger quantities since you’ll use more than you think. Organic is always preferable. 5.A Spray Bottle For misting during germination. A simple pump spray bottle costing a dollar or two is absolutely fine. 6. Something to cover the tray During the germination and blackout phase (the first 3 to 4 days), you need to block all light. An upturned identical tray works perfectly. A sheet of cardboard or a dark plastic bag achieves the same result. 7. A light source A bright, south-facing windowsill often provides enough light. If your home doesn’t get great natural light, a simple grow light makes a big difference. Even a cheap LED strip positioned 2 to 4 inches above the tray will produce excellent results. 🛒 The One Tool That Makes Everything Easier If you want to skip the tray-hunting and seed-sourcing and just start growing today, I highly recommend the Back to the Roots Organic Microgreens Grow Kit .It comes with an organic seed mix, a grow tray, growing medium, and clear instructions — everything in one box, ready to go the moment it arrives.
