How To Grow Microgreens in Sprouting Trays — Cheaper & Smaller Than 1020s!

How to grow microgreens in sprouting trays with spicy oriental mustard on coco coir, from seeding to day six, with bottom watering tips. We've found that growing microgreens in sprouting trays can be quite difficult, but there are only a few hurdles to get over. In this step-by-step tutorial, we grow spicy oriental mustard in the green sprouting trays you can find on Amazon, which we've been using more in our grow space because they do such a great job. We walk through weighted germination, blackout, and the move into light, including the bottom watering mistake that makes crops fall over. ➽ Read the full written guide: https://onthegrow.net/blogs/microgreens/how-to-grow-microgreens-using-sprouting-trays How we grew it: ✅ Medium: 2 cups of coco coir spread evenly in the tray ✅ Seed: 10 grams of spicy oriental mustard, which is about 1 tablespoon ✅ Trays: only the two trays that come in the set. The white tray comes out, the bottom tray is cleaned out and placed on top, and it becomes the weight and blackout tray ✅ Weight: a mini paver of about 7 pounds on top of the seeds, on a dark shelf ✅ Watering: watered well but not saturated, twice a day, in the morning and later in the day ✅ Day 2: seed hulls sticking to the bottom of the top tray is a good sign, since it means the tray and weight are making contact with the seed ✅ Day 3 blackout signs: radicles are going into the medium, every seed has germinated, and the seed hulls are removed. Then we flip the top tray into a blackout dome ✅ Day 4: one more day of blackout to get the crop a little taller and easier to harvest ✅ Day 5 light: out of blackout at the right height, under 20 watt shop lights, with the first bottom water of Ocean Solution water mixture ✅ Bottom watering: with our 10x20 trays we start with about 1/4 cup. With these sprouting trays there is a sizable gap at the bottom, so we needed 2 and a half cups before the water touched the bottom of the tray holding the medium ✅ Day 6: the crop looks happy and healthy, and we check for signs of over watering, under watering, and pathogens in the crop and the medium When you see a true leaf, it is generally time to harvest. If you're unsure, pluck one microgreen and taste it. Watch the height too, because you don't want them falling over. After harvest we compost the medium. This video ends on day 6, before harvest.
