Radish Guide

Here's our complete guide for growing radish greens in the Fieldhouse — follow these steps, reference the video and FAQs, and you'll do great. We're rooting for you!

REHYDRATE COIR PUCKS | DAY 1

1. Open coir pack and transfer both pucks into a standard size mixing bowl
2. Using included Leath measuring cup, pour two cups of water over the coir discs
3. Wait 5 minutes to allows coir fibers to expand and fully absorb water
4. After pucks have sucked up all water, begin to work coir with hands
5. Break up any clumps and continue mixing until coir has been fully rehydrated and loosened
6. Once coir has been thoroughly mixed up, transfer into top tray with holes

PLANTING | DAY 1 — NO GROW LIGHT NEEDED

1. Open radish seed pack and transfer to dry Leath measuring cup for easy distribution
2. Carefully begin to spread radish seeds across rehydrated coir, paying special attention to evenly disperse and avoid any clumping of seeds — even distribution helps ensure maximum germination and yield size
3. Using included spray bottle, lightly mist seeds until visibly damp, but not soaked
4. Cover seeds with germination lid and press down gently, ensuring seeds have made contact with grow medium
5. It’s often helpful to make note of the day you planted seeds to track growth progress 

GERMINATION PHASE | DAYS 2-3 — NO GROW LIGHT NEEDED

7. Lift germination lid once per day to visually check for seed sprouting and coir hydration levels
8. If soil is looking dry, use spray bottle to spritz seeds from above — remember, the soil should be damp, but not soaked
9. Once 85 - 90% of the tray has sprouted and early-stage leaves are beginning to form, remove germination lid and expose seedlings to grow light – utilize the Fieldhouse’s built-in timer for an automated schedule of 12 hours of continued light followed by 12 hours off

TO NOTE: There is no bottom watering required for radish during germination. At this stage, it’s common for seeds to exhibit white, fuzzy hairs at the base of the stems, which are easily confused with mold — read our guide on ROOT HAIRS VS MOLD.

GROWTH PHASE | DAYS 4-12

10. Inspect coir, and if starting to dry out, pour 1 cup (250 ml) of water into bottom tray via watering ramp using included measuring cup
11. Continue to water as needed — typically once every 1 - 2 days — until harvest
12. If soil is visibly soaked through, hold off on watering that day — VIEW OUR WATERING GUIDE
13. Radish greens will be ready to harvest once greens have reached 2 - 3 inches (50 - 75 mm) in height, or approximately 8 - 14 days after planting
