FAQ

Is this fertilizer safe for edible plants?

Yes. The formula contains only essential mineral nutrients (NPK + Ca, Mg, S) and contains no heavy metals. It is safe for vegetables, herbs, and fruits when used as directed.

Can I use it in hydroponic systems?

Yes. This fully soluble liquid fertilizer leaves no sediment and is ideal for all hydroponic systems, including micro-hydroponics where organic fertilizers are not suitable.

What makes this liquid fertilizer better than granular options?

Liquid nutrients are immediately available for plant uptake. Unlike granular fertilizers, there is no waiting period for dissolution, resulting in faster and more consistent absorption.

How do I adjust feeding for different growth stages?

Our A+B two-part system includes a clear stage-by-stage feeding chart. Simply adjust the ratio and concentration according to the seedling, vegetative, or flowering phase for precise nutrition.

Is there a risk of overfeeding or burning my plants?

When properly diluted according to the feeding chart, the fertilizer is safe for all growth stages, including seedlings and young plants. Accurate dosing prevents nutrient burn and stress.

Does it affect the taste or quality of edible crops?

No. The formula uses only pure mineral nutrients that plants naturally require and does not alter flavor or crop quality when used as recommended.

What sizes are available, how should I store it, and where can I get feeding advice?

The product is available in multiple sizes up to 4 gallons, with both retail and wholesale options. Store in a cool, dry place away from direct sunlight with containers tightly sealed.
