🌱 Three crops, one tray, no soil! In this step-by-step tutorial, Mandi shows you how to grow Spicy Oriental Mustard, China Rose Radish, and Purple Sprouting Broccoli microgreens all in a single 10x20 tray using a reusable silicone grow mat. From setup to harvest in just 8 days — the end result is a vibrant, flavorful spicy microgreen blend. Here's what we cover: ✅ How to divide a 10x20 tray into thirds for three different varieties ✅ Seeding each variety with proper spacing and density ✅ Managing germination, blackout, and light transitions for a multi-crop tray ✅ Bottom watering techniques and daily watering adjustments as plants grow ✅ Identifying each stage of growth from Day 1 through Day 8 ✅ Harvesting all three varieties and mixing them into a spicy blend ✅ Weighing the harvest yield from a single tray ✅ How to clean, sanitize, and reuse the silicone grow medium (including ozone sanitization) ✅ Composting leftovers and preparing the tray for the next grow Growing multiple microgreen varieties in one tray is a great way to save space and create custom blends at home. The key is choosing varieties with similar grow timelines — Mustard, Radish, and Broccoli all hit harvest around the same window, making them an ideal combination. Using the reusable silicone medium means no soil, no coco coir, and no mess — just clean, efficient growing with a medium you can sanitize and reuse indefinitely. ➽ Learn even more about Reusable Grow Mediums through our blogs on the topic: https://onthegrow.net/blogs/microgree... 🔗 PRODUCTS IN THIS VIDEO ➽ Spicy Oriental Mustard Seed: https://onthegrow.tv/SpicyORMustard ➽ Purple Sprouting Broccoli Seed: https://onthegrow.tv/PurpleSproutingB... ➽ China Rose Radish Seed: https://onthegrow.tv/ChinaRoseRadish ➽ Sample Pack Reusable Grow Medium: https://onthegrow.tv/ReusableSamplerPack ➽ Reusable Grow Medium: https://onthegrow.tv/ReusableGrowMediums ➽ 1020 Trays for Microgreens: https://onthegrow.tv/10x20Trays ➽ Tray Clip Label Tabs: https://onthegrow.tv/TrayLabelers ➽ Ocean Solution 2-0-3: https://onthegrow.tv/OS203 ➽ Sprayer for Watering: http://homedepot.sjv.io/Z9NQ0 ➽ Ozone Machine: https://onthegrow.tv/OzoneMachine ➽ Grow Rack Build Supplies: https://onthegrow.tv/MicrogreenPepper... ➽ LED Lights: https://onthegrow.tv/Lights20W ➽ Harvesting Knife: https://onthegrow.tv/HarvestingKnifeM... 📚 MORE RESOURCES ➽ Read Our Blog: https://onthegrow.net/blogs/microgreens ➽ FAQs: https://onthegrow.net/pages/faq ➽ Books, Online Course, Free PDF Downloads: https://onthegrow.tv/Education 🛒 SHOP ON THE GROW ➽ https://onthegrow.net/ We ship USA & Canada 📲 CONNECT WITH US ➽ Facebook:   / onthegrowfarms   ➽ Instagram:   / onthegrowfarms   ➽ All Our Links: https://linktr.ee/Onthegrow ⏱️ TIMESTAMPS 0:00 – Introduction to Growing Mustard, Radish, and Broccoli Together 0:11 – Setting Up 10x20 Tray with Silicone Reusable Medium 0:33 – Adding Tray Clip Labeler for Easy Identification 0:49 – Seeding the Tray: Broccoli, Radish, and Mustard 1:28 – Misting for Germination and Trapping Humidity 2:07 – Day 2: Watering and Checking Seed Progress 3:19 – Day 3: Seeds Cracking Open and Preparing for Blackout 4:23 – Day 4: Ready for Blackout, Keeping Plants Hydrated 5:00 – Day 5: Exposing to Light and Bottom Watering 6:00 – Day 7: Increasing Watering as Plants Grow 6:36 – Day 8: Ready to Harvest Triple Variety Tray 7:02 – Harvesting Mustard, Radish, and Broccoli Microgreens 7:50 – Mixing Microgreens for Flavorful Blend 8:16 – Cleaning and Sanitizing the Grow Medium for Reuse 9:38 – Using Ozone to Sanitize and Reuse the Medium DISCL
