Review: Highly Recommend this Premium Bloom Booster - Highly recommend this Bloom Booster. I'm NOT getting paid or compensated for this review in any way. This is an honest review based on my personal experience. So far I have used it on 5 cycles with AUTOS and PHOTOS and they all love it. If you're using living soil setup and don't have room on top of your container to add more worm castings and/or BuildASoil BuildAFlower, then this product Flower Finisher is what you need to solve that problem and it will make a big difference in the end result. I used to use Roots Organics Terp Tea Bloom Booster but after trying the Flower Finisher I noticed a difference, plants seem to prefer the Flower Finisher during the weeks 5 through 8 versus using Terp Tea Bloom Booster from transition until 2 wks from harvest. I use 1 Tsp per Gallon of Soil as a top dress with SEA-90 and Rootwise Mycrobe Complete ¼ Tsp biweekly and Rootwise Elixir 5mL weekly and SLF-100 enzyme at 5mL x gallon weekly along with my Moringa FPE - Fermented Plant Extract, Moringa/Comfrey/Kelp/Alfalfa/Stinging Nettle FPE, my Soil Inoculant which is just like EM-1 but much better, and WheyWorks ProBiotic ferment which I make myself for my business and personal grow, and also have them listed on eBay for others to try them. These ferments help breakdown Flower Finisher and make it more available for uptake and much quicker, suppresses pathogens, delivers vitamins, minerals, trace elements, NPK, micro and macronutrients, they are made from plants which produce their own rooting hormones, which means that they drastically help with germination, every transplant to eliminate transplant shock, and stimulate roots and growth. I have them listed on eBay for people to try them and see how big of a differencev they really make. HAPPY GROWING 🌱🌿🪴🌵🌴🌳

## Features

- ORGANIC PK FINISHING BOOSTER — THE ORGANIC REPLACEMENT FOR SYNTHETIC FINISHERS — Flower Finisher is a highly concentrated organic PK additive (1-5-7) designed for the final 4 weeks of flowering. Add it alongside Pride Lands Bloom, Gaia Green, or any bloom base to stack P/K loading in peak flower — without synthetic chemicals. Not a standalone base fertilizer; use with a full-cycle program.
- 9 OCEAN & EARTH-SOURCED INGREDIENTS — NO SYNTHETIC CHEMICALS — Derived from: crab meal, seabird guano, oyster shell, alfalfa meal, rock phosphate, fish bonemeal, glacial rock dust, sulfate of potash, and kelp meal. Enhanced with 1% humic acid and 2% biochar. Every ingredient chosen for its role in P/K delivery, terpene development, and soil biology. Nothing synthetic, no cheap fillers.
- TERPENES UP. DENSITY UP. AROMA UNLOCKED — During the final 4 weeks of bloom, Flower Finisher's organic P/K stack adds natural weight and structural density to flowers while its biology-supporting ingredients unlock terpene profiles that synthetic finishers can't match. Verified growers report 'subtle terps I hadn't smelled before' and results that 'surpassed expectations' vs. synthetic finishing programs. Apply weeks 5–8, or use at transition and again at week 4.
- CONCENTRATED FORMULA — 5LB BAG LASTS NEARLY 2 YEARS — At 1 tsp per gallon as top dress, a 2lb bag covers multiple grows for most home cultivators. One verified grower bought a 5lb bag in 2023, grew 4–6 plants every 3–4 months, and still had nearly 3lb remaining after two years. Per-use cost is a fraction of liquid bloom boosters — the $49 price tag disappears fast when you see the yield per tablespoon.
- WORKS IN ANY GROW — AUTOS, PHOTOS, LIVING SOIL, COCO — Flower Finisher works alongside any bloom base — Pride Lands Bloom, Gaia Green, Roots Organics Terp Tea, or any organic or synthetic bloom program. Compatible with all growth media (soil, coco coir, soilless). Use as top dress, compost tea, or soil drench. Not for aeroponic or recirculating hydroponic systems. Verified on 5+ cycles by multi-strain growers. GreenGro Biologicals — organic soil science since 2011.
