Thinning Your Sprouts for Healthier Plants

Edited

How to Thin

To thin = to remove

It may sound counterintuitive, but removing some plants in each yCube increases your plants’ health & ability to grow large.

To give the best chances of germination success, each yCube is usually seeded with 6 seeds (for big seeds like peas, we use 3 seeds per yCube). Each stem or sprout coming from the yCube is its own plant, and it's normal for many to sprout at once. Thinning gives the remaining plant(s) increased access to light, water, nutrients, air, & space.

Thinning is variety-specific

Typically, most fruiting plants & leafy greens should be thinned to 1 plant per yCube, while most herbs & bushy plants such as flowers should be thinned to 3 plants per yCube. There are very few plants that do not require any thinning. Follow the table below for each variety's thinning rule.

When to thin

It's best to thin your plants after they've been exposed to plant food for 1 week, helping you to see which are the tallest sprouts versus which ones won't make the cut. Kelby will send you a task reminder in the app when it's time to thin after germinating your Welcome Kit or starting fresh with all new plants on your Gardyn.

Use clean scissors

Snip the smallest sprout(s) above the rockwool, leaving the correct number of sprouts to continue growing.

  • Tip: Most sprouts are edible, so try ‘em out! Just avoid sprouts from fruiting plants & flowers.
