Frequently Asked Questions

When during a plant's life cycle should this formula be used?

It's well suited for fertilizing young seedlings, transplants, clones, and newly set root cuttings, rather than established plants further along in their growth cycle. That early-stage focus is what distinguishes a clone starter formula from a general vegetative or bloom feed.

What does this formula do for root development?

It promotes fast root development and extensive root system growth, which matters most during the vulnerable early period when a seedling, transplant, or cutting is still establishing itself. A strong root system at this stage sets up healthier growth through the rest of the crop cycle.

Is this suited to clones specifically, or just seedlings?

Both — the batch's own labeling calls out young seedlings, transplants, clones, and newly set root cuttings together as the intended use cases. All of those share the same need for fast, extensive root establishment that this 15-6-17 formula is built to support.

What size is this listing?

This is the 25lb size option. Both sizes share the same 15-6-17 Clone Starter formula, so the choice comes down to how much product a grower needs on hand.
