When I first saw the Biosta sprouter, I wondered if something with such a basic design could really work to grow sprouts indoors (or out).

How the Biosta Sprouter Performed

April 1, 2010 There's nothing special about the unit, except that the plastic seems durable and the trays all nest into each other nicely. You can tell which should be the bottom (water) tray - it has no ridges in the bottom. The lid fits loosely on the top tray.

It's a very basic operation but it works reasonably well. First you place the drainage cap in each tray, so the sprouts don't lodge there and hinder drainage, add your choice of sprouts to the three trays - the amount can vary but you want just a nice coverage in the bottom of each tray (about 1 tablespoon of seeds). Each tray should nest properly in the one below. When stacked, add about a cup of water, sprinkling over the top tray only. A little water will remain in that tray, but the rest will filter through to the next layer, then to the third with excess water accumulating in the very bottom tray, which you could drain each day.

The sprouter should be covered all the time and placed in a sunny location indoors or out. Every day, apply water and re-cover - that is the only thing you need to do to grow sprouts in this sprouter. In 3-4 days, your sprouts are ready to eat - add to salads or sandwiches, or use as garnish. Sprouts must come out of the sprouter after they have sprouted, or they will become too long, stringy and they could start to deteriorate at this point, from too much humidity. So there is no gain by growing any longer than 3-4 days.

Overall Impression

It's an extremely basic design - water flows through each tray and humidifies enough to effect a growing cycle for sprouts. I've grown several types of sprouting seeds in the Biosta, with my favorite being alfalfa, radish and mung bean and every time, the batches were done in about three days. Remove when done, rinse the sprouts well under cold water, drain, bag and refrigerate. Clean the sprouter with warm soapy water and rinse well making sure to remove any sprout residue that has lodged in ridges of the tray bottoms. The sprouter is then ready for another batch or to store.

Though the Biosta is designed only for smaller sprouting seeds such as alfalfa, radish or salad mixes, I've had no problem growing mung bean sprouts in this sprouter. A sunny location and warm/room temperature is all that's needed to effect the growing process.

Growing sprouts at home means - no fertilizer, no soil and no pests. It's quick, easy and very rewarding. Sprouts are a very nice addition to salads, sandwiches and cold dishes. Sprouting seeds are available from various retail outlets, online sources and garden seed centers.

This sprouter is best for small seeds as recommended, larger seeds could overwhelm the sprouter. Simplicity wins with this easy sprouter - it works well and cleans up just as easily. If you like sprouts, you can grow them yourself at home economically with the Biosta. The retail price seems to vary per dealer, but generally it's in the $30-$40 range.
