Orchid Nerd K-Lite Fertilizer Formula (12-1-1-10Ca-3Mg) – 8 oz
Low Potassium, Urea-Free Formula for Long-Term Orchid Health

Orchid Nerd K-Lite is a specialized fertilizer designed to give orchids, aroids, and other epiphytes exactly what they need—and nothing they don’t. With a balanced 12-1-1 formula enhanced with 10% calcium and 3% magnesium, this blend supports strong roots, vibrant foliage, and long-term health while avoiding the salt buildup and nutrient imbalances that high-potassium fertilizers can cause.

Developed with insights from Dr. Bill Argo, the creator of the original MSU orchid blend, K-Lite mimics the natural low-potassium, calcium-rich nutrition orchids receive in the wild. This 8 oz resealable pouch is perfect for small collections or those using reverse osmosis or rainwater.

Why Growers Trust Orchid Nerd K-Lite 12-1-1:

Orchid Nerd K-Lite was developed in response to studies showing that excessive potassium in fertilizers can interfere with calcium and magnesium uptake. Over time, this can stress root systems and reduce plant vigor. By lowering potassium and eliminating urea, this formula helps keep orchids fed, balanced, and thriving—especially in bark or moss-based mixes that tend to hold on to potassium salts.
