Grow Broccoli Microgreens Without Soil | 7x14 Silicone Tray Kit Tutorial

We grew broccoli microgreens without soil on the silicone reusable grow medium in our 7x14 tray kit and harvested 186 grams from one tray in 9 days. The 7x14 white tray kit comes with a reusable silicone grow medium, so there is no soil and no mess. We set everything aside except the reservoir tray, added three cups of water to it, and placed the mesh tray on top. We added the silicone medium and misted it before seeding to help prevent seed bounce, then spread 16 to 20 grams of broccoli seed on the 7x14 tray. We misted the seeds with water or a prophylactic spray, set the humidity dome on upside down, and moved the tray to a dark shelf to germinate. By day 2 the seeds were opening up. We noticed slow germination in the middle, right where the humidity dome has small holes, so we gave that spot a little more water. On day 4 the middle had germinated properly and we flipped the lid into a humidity dome. Twenty-four hours later, on day 5, we removed the dome for the rest of the grow and introduced the tray to light. Since the broccoli was now in light, we started bottom watering with about four cups of Ocean Solution water, refreshing the reservoir first. On day 9 it was harvest day. We harvested with a sharp knife and a scale, taking care not to cut the grow medium, and got 186 grams from this single tray. After harvesting we remove the roots from the medium and compost them, store the microgreens in a bag in the fridge, then clean and sanitize the medium for reuse. Prefer coco coir in this same kit?
