Grotek Insta-Green, 1 L

A Dark Greening Solution That Restores Lush Color and Vigor, 1 L

Seedlings and cuttings that come out of a stressful transplant or a stretch of underfeeding often show it first as yellowing, dull foliage rather than any dramatic symptom, and waiting it out costs growth time the plant won't get back.

This 1 L size is sized for smaller-scale foliar treatment, applied as a foliar spray directly on affected seedlings or cuttings.

Frequently Asked Questions

What causes the yellowing Insta-Green addresses?

Yellowing is commonly caused by underfeeding or the stress of a recent transplant, both of which can leave seedlings and cuttings short on the nutrients that keep foliage green. Insta-Green targets that visible symptom directly through the leaf.

How should I apply Insta-Green?

Apply it as a foliar spray, directly to the foliage of affected seedlings or cuttings, whether they're growing indoors or outdoors. Spraying rather than root-feeding is what allows it to act quickly on visible yellowing.

Is this product suited for seedlings and cuttings specifically?

Yes, it's formulated to eliminate yellow leaves in seedlings and cuttings, which are more sensitive to underfeeding and transplant stress than established plants. That's the stage where a fast greening response matters most.

How quickly will I see results?

As a foliar spray, Insta-Green is designed to act quickly on visible yellowing since the leaf tissue absorbs it directly rather than waiting on root uptake. Most growers see improved color within days of application.
