Alright growers, if you’re looking to slap some serious weight on your buds, this one’s a no-brainer. House & Garden Top Booster is the real deal — a powerful PK13/14 bloom stimulator that kicks your plants into full floral overdrive. We use it, we love it, and we swear by it during week 5 of flower to really turn up the heat.
🌿 Why It Works (aka Science but Make It Sexy):
Plants naturally ease off the nitrogen and start begging for more Phosphorus (P) and Potassium (K) during the flowering stage. Top Booster delivers the goods in just the right ratio, helping shift all that energy away from leaves and stems and straight into bulking up those juicy buds.
💪 Bonus Boost – Iron (Fe) FTW:
What sets Top Booster apart? It’s got a special form of Iron (Eddha-Fe) that reduces yellowing leaves and jumpstarts the production of ethylene — basically a natural plant hormone that tells your grow, “Hey, let’s wrap this up and bloom like beasts.”
⚙️ Works in Hydro, Coco, or Soil
We don’t care if you’re running DWC, coco bags, or straight-up organic beds — this booster plays nice in every hydroponic or soil-based setup. That’s why it’s a favorite at The Grow Guys HQ.

🔥 Grow Guys Tip:
Top Booster is like the final gym session before beach season. Your plants won’t just bloom — they’ll strut into harvest like they own the place.
