SUNPRO Seed Sprouter Tray BPA Free PP Soil-Free Big Capacity

The Verdict

If you’ve ever tried growing sprouts in a mason jar, you know the drill: rinse, drain, repeat — and hope you don’t end up with a sour-smelling science experiment. The SUNPRO Seed Sprouter Tray takes a different approach, and honestly, it’s one that makes more sense for anyone serious about adding fresh sprouts to their daily meals.

This isn’t a fancy gadget with electronics or timers. It’s a straightforward, soil-free growing system built around a simple principle: good drainage and airflow prevent the two biggest sprout killers — mold and stagnation. At 4.2 stars from 210 Amazon ratings, it’s clearly working for most people. But let’s dig into whether it’s right for you.

What You Actually Get

The kit includes three stackable trays, each with a perforated growing surface, plus a base tray and a lid. The whole thing stacks into a compact tower that takes up about the footprint of a dinner plate. The PP plastic is food-grade and BPA-free, which matters more here than in most kitchen gadgets because you’re eating what grows in it.

Each tray has fine drainage holes across the entire surface, and the trays are slightly angled. That angling is the smart design touch — it directs runoff to one corner rather than letting water pool in the middle, which is where mold typically takes hold. As shown in the product image, the stackable design lets you grow different seeds at different stages simultaneously. Start a new batch in the top tray while the bottom trays are already sprouting.

Real-World Performance

The system works exactly as intended for medium-to-large seeds. Mung beans, broccoli, alfalfa, lentils, and sunflower seeds all perform well. You soak the seeds, spread them on the trays, rinse twice daily, and drain. The drainage holes do the heavy lifting — you don’t have to tilt the whole unit like you do with jar sprouters.

That said, there’s a catch: there’s no collection tray or spout. When you rinse, water flows through to the base, but you have to lift the stack and dump it yourself. It’s not a dealbreaker, but it’s one extra step that some competing designs eliminate with a reservoir spout.

The other limitation is seed size. Chia, flax, and amaranth seeds are small enough to fall through the drainage holes. You can solve this with a paper towel liner or by sticking to larger seeds, but it’s worth knowing before you buy.

What Buyers Keep Saying

The consensus in the reviews is consistent. One buyer noted, “I’ve tried three different sprouters and this is the first one where I didn’t get mold on my broccoli sprouts.” Another mentioned the capacity: “I can grow enough alfalfa for the whole week in two trays — the third tray is for mung beans.” The BPA-free material gets called out repeatedly by health-conscious shoppers, which aligns with the product’s positioning.

Where It Falls Short

Let’s be honest about the downsides. The manual draining is the biggest annoyance — every rinse cycle ends with you tilting the base over the sink. The lack of a solid liner tray means you’ll occasionally lose a few small seeds to the sink drain. And if you’re looking for an automated system, this isn’t it. You’re committing to twice-daily rinsing, roughly five to seven minutes total per day.

Who Should Buy This

The SUNPRO is ideal for:

• Home cooks and salad enthusiasts who want a steady supply of fresh sprouts without buying them at $4 per clamshell at the grocery store
• Health-focused households concerned about BPA and plastic quality — this passes that test
• Beginners who want a forgiving, low-tech introduction to sprouting
• People with limited counter space — the vertical design is genuinely space-efficient

Skip it if you’re looking for an automated system, if you primarily want to sprout tiny seeds, or if you’d rather not deal with manual draining.

FAQ

How often do I need to rinse the seeds? Twice daily — morning and evening. More if your home is warm and dry. Each rinse takes about a minute.

Can I sprout different seeds at the same time? Yes, that’s the strength of the three-tray design. Just keep seeds with similar sprouting times together so you can harvest them at the same stage.

Is the plastic really BPA-free? Yes, the manufacturer certifies it as food-grade PP, which is BPA-free. Multiple reviewers confirm the material has no chemical odor or taste.

The Verdict

Buy it if you want a reliable, chemical-free way to grow sprouts at home and don’t mind a daily two-minute rinse routine. The drainage design genuinely prevents mold, the BPA-free material is reassuring, and the vertical footprint fits almost any kitchen.

Skip it if you want hands-off automation, prefer sprouting tiny seeds exclusively, or expect a fully self-contained drainage system.

Rating: 4.2/5 — A solid, well-designed sprouting system with one notable design gap (no collection spout) that keeps it from being perfect. For the price point and what it delivers, it’s a practical purchase that pays for itself after a few weeks of sprouts you’d otherwise buy at the store.
