How does Yield-Masta work?

Yield-Masta is a 4-part, 2-stage additive.

Stage 1: Immediate Flower Production

This stage stops vegetation growth and triggers immediate flower production, usually within 3-5 days. It also increases the number of flowering sites and promotes stem thickening for better yield support.

Stage 2: Enlargement and Hardening

During this stage, you'll notice your flowering sites enlarging and eventually hardening, ensuring robust and healthy blooms.

Contents and Ingredients:

Each package includes 4 bottles, each containing 100mL of Yield-Masta solution. The formula is enriched with Gibberellins, Auxins, PGRs (Plant Growth Regulators), Vitamins, and Minerals.

Safety Instructions:

Keep out of reach of children.
Do not ingest internally.

Experience the power of Yield-Masta Sudden Impact and witness extraordinary flower growth in your plants!

Growers First, Retailers Second

Welcome to The Grow Guys

We built The Grow Guys from the soil up — well, coco and perlite. Before we sold gear, we bought it, ran it, and learned the hard way what's worth the money and what ends up in the shed. That's the filter everything on our shelves passes through. No sales scripts, no rebadged junk, no telling you what you want to hear. Just gear we'd run ourselves and advice from people who actually grow. Chasing higher yields, tighter flowers, or your first harvest? You're in the right place.
