Yes. The Fieldhouse was designed to make growing feel simple, even if you’ve never grown anything before. Microgreens grow quickly, so you’ll see progress in days instead of weeks, and the built-in grow lights mean you don’t need a sunny window or outdoor space. The goal is easy, repeatable harvests — not a steep learning curve.

Your Starter Set includes the Fieldhouse grow system, six Leathlet seed-and-coir packs, a germination lid that doubles as a cutting board, a glass spray bottle, and a glass measuring cup. In other words, everything you need to start growing right away — not just the hardware.

The Fieldhouse is designed for microgreens — young vegetable and herb seedlings harvested early for fast growth, concentrated nutrition, and big flavor. Your Starter Set includes six varieties: broccoli, arugula, radish, medley, pea shoot, and sunflower.

You can also use the Fieldhouse to start seeds before transferring them into larger pots, but it’s optimized for microgreens.

Most varieties are ready to harvest in 7 to 12 days. That quick turnaround is part of what makes the Fieldhouse so satisfying — you don’t have to wait long to feel successful, and once you find your rhythm, you can keep greens growing week after week.

Yes. The Fieldhouse is a great way for kids to watch seeds sprout, grow, and become food in just days. Younger growers may need help with setup, watering, and harvesting, but the process is simple, hands-on, and fun to follow.

Each tray grows up to 5 oz of microgreens, depending on the variety. That’s enough to add a generous handful of greens to salads, sandwiches, eggs, bowls, and dinners throughout the week — all from a small countertop footprint.

No. The Fieldhouse has built-in full-spectrum LED grow lights, so it doesn’t need natural light or outdoor space. Its footprint is compact enough for a kitchen counter, apartment, office, or classroom. It works best somewhere with good airflow and low humidity.

Very little once you’re set up. Assembly takes about 10 minutes, and the routine is simple: plant, cover during germination, turn on the light once seeds have sprouted, water every day or two, then harvest. The built-in grow light and optional 12-hour timer take most of the guesswork out of it.

Not really. Leathlets are pre-measured, so there’s no loose bag of soil to scoop or store. The coir expands with water, the tray keeps everything contained, and cleanup after harvest takes just a few minutes.

After your Starter Set, the only thing you’ll need to restock is Leathlets — our seed-and-coir grow packs. Each pack grows one full tray. You can buy them one at a time, in bundles, or on subscription to save 20% and avoid running out.

We accept returns within 30 days of delivery for Fieldhouses that are unused and in their original packaging. To start a return, visit our Return Policy page or email us at hello@growleath.com. All seed sales are final.

Leathlets are our seed-and-coir grow packs. Each one contains the exact amount of seeds and growing medium needed for one full tray in the Fieldhouse. They come in six varieties: broccoli, arugula, radish, medley, pea shoot, and sunflower.

Yes. Our seeds are certified USDA organic and non-GMO.

Coir, pronounced “coy-er,” is a growing medium made from coconut fiber. It holds moisture well, supports healthy germination, and is a more sustainable alternative to traditional soil. It also happens to be very satisfying to reconstitute — just add water and watch it expand.

Leathlets are measured for the Fieldhouse grow tray, but they can technically be used in another compatible growing setup. Just keep in mind that grow times and yields are optimized for the Fieldhouse, so results may vary.

For your first grow, we recommend broccoli, radish, arugula, or medley. They germinate quickly and don’t require pre-soaking. Sunflower and pea shoot are also beginner-friendly, but they do need a few hours of soaking before planting, so they add one extra step.

Leathlets are sealed to preserve quality for over 2 years from the packing date, so you can stock up without worrying about using them right away.

Leath is based in New York. The Fieldhouse is manufactured overseas, and our seeds and coir are sourced and packed in the USA.

We don’t recommend mixing varieties in a single tray. Each seed has its own germination and grow timeline, so one variety per tray gives you the best results. With a 7 to 12 day turnaround, you can easily try something new each week.

Microgreens are a cut-once crop, so they usually don’t regrow after harvest. Occasionally, you may see a small second wave from seeds that sprouted later, but the main harvest is one and done. After cutting, compost the coir, rinse your tray, and start fresh.

Hand wash your grow trays and germination lid after every harvest using dish soap or food-grade hydrogen peroxide. Give them a good scrub to remove residue, dry thoroughly, and you’re ready to plant again.

After germination, microgreens do best with about 12 hours of light per day. The Fieldhouse has a built-in 12-hour timer, so you can turn the light on once and let it cycle automatically.

Anywhere indoors with good airflow and low humidity works well. Kitchens, living rooms, offices, and classrooms are all great options. The Fieldhouse doesn’t need natural light, so placement is flexible — just avoid very humid or poorly ventilated spots, like directly next to a stove or in a bathroom.

Once your seeds have sprouted and the germination lid is off, water every 1 to 2 days, or when the coir starts to look dry. The goal is consistently damp — not drenched. When in doubt, check the coir before watering. If it still looks moist, give it another day.

Root hairs are thin, white, fuzzy strands that can appear near the base of your seeds during germination. They’re often mistaken for mold, but they’re completely normal — and a sign that your seeds are forming healthy roots. Mold usually has a musty smell and appears on the leaves or surface rather than just around the roots.

Most varieties are ready in 7 to 12 days. The best signal is when the first set of true leaves begins to appear — that’s when flavor and nutrition are at their peak. Broccoli, arugula, radish, and medley can stay on the tray a little longer, while sunflower and pea shoot are best harvested within about 15 days before their texture and flavor begin to change.

The most common issue is watering — either too much or too little. Seeds should stay consistently damp, but never waterlogged. If you adjust your watering, they’ll often bounce back.
