- Flower Stacker, 0-7-5 Bloom Booster, Vitamin B1, 32 Ounce

Buy there's product that works really well

Seems very good hopefully so

This Bloom Booster with Vitamin B1 is fantastic! It’s helped my plants produce stronger blooms and healthier foliage—everything looks more vibrant and lush. The added Vitamin B1 seems to reduce transplant shock and supports overall plant vigor, especially when introducing new plants to the garden. It’s easy to mix and apply with my watering routine, and I’ve noticed that flowers stay fuller and more abundant throughout the season. The formula feels high‑quality and effective without being overly complex. If you want a reliable way to promote better flowering and stronger, healthier plants, this bloom booster is an excellent choice. Highly recommend!

A newer design is advertised than what I got and there's no expiration date but I'm still giving 4 stars because it worked just as well as the one I used to use at half the price and I still have half left. I would roll the dice and buy again.

Great secret to add to feeding

Blooms are popping!!!

I use the whole Humboldt's Secret nutrient line on plants grown indoors in tents with automated lighting, circulation and exhaust fans and manual feeding, watering, temperature and humidity controls. My flowers are cup quality, every time. Top quality nutrients, broad spectrum, easy schedule and dosing and super reasonable compared to other brands with comparable offerings. On average, I'd say my return on investment in yield:nutrient is about 50:1. Hard to argue that. I'm a believer.

Haven't used yet am looking forward to. Directions on container to small to read with 150 readers and magnify glass. My spouse with progressive lens glasses and magnifier thinks she read correctly. Having to convert ml to ounces normally not an issue however having to measure a 1/4 tsp. for a gallon wasn't easy pouring from a .924 liter container to a teaspoon. I guess I could have spent the day looking for a 1/4" tsp. Nevertheless explicit warnings of accurate. measurement, timing of 3 weeks after flower bloom, to apply 1st dose is scary with all the warnings about plant burn out. We'll see how it goes.
