For soil-less methods of sprouting, Earths General Store carries sprouters (biosta and jar method)
Trays, Inserts, Cells/Pots, and Plastic Domes
We use the heavier weight trays because they last longer, locally sourced from: Apache Seeds. For microgreen inserts (cells) stick with the 01 series. Ex. 601, 801, 1001, 1201 etc. This means 6, 8, 10 or 12 compartments/tray which allows you to grow more than one variety of seed in each tray. Apache is also a great source for cells and pots for transplants or you can make your own out of yoghurt containers (just punch some holes in the bottom for drainage), egg cartons, or DIY newspaper pots.
Shop lights work well (find at any hardware store) but sunblasters are our favourite. A sunny south facing window also works well!
