It is a unique plant growth enhancer and it fits into your gardening or crop farming regimen at any level. Blackwater Plus harnesses the combined power of natural plant hormone boosters and beneficial micro organisms to push your plants beyond their maximum potential. Water it into your soil and benefit from: fuller plants with more branch nodes (without having to resort to destructive practices such as "supercropping"), more flower/fruit sites per plant, more calyxes per flower site resulting in tighter and more attractive flowers, healthier more fertile soil, a stronger plant immune system, superior root growth, much less disease and fungus, and a better seed germination rate. Add to your supersoil or organic soil mix for rapid breakdown and a richer end result. It is safe but powerful and helps all plants in your garden including: tomatoes, roses, citrus trees, cover crops, peas, squash, melons, peppers, cannabis, etc... Plants will benefit from as little as one application per season and a small bottle with last a long time. All ingredients are naturally derived and sustainably sourced. This is a non-genetically engineered product. How is Blackwater+ different?: At Sunwheel, we have the philosophy of adopting what does work, not what should work (or what only sounds good in marketing). Exogenous plant hormones by themselves (as sold by competitors) are actually quite weak. We have discovered a powerful catalyzer, that when used with our finely tuned phytohormones, produces many times the effect of normal growth enhancers. Blackwater concentrate is equivalent to buying 8 gallons of grow product, can replace many other products on the market, and can save you money on your way to becoming a professional grower. Happy Growing! ## Features - Uniquely benefits all types of plants! - Finely tuned, natural plant hormone agents produce rapid, dense growth, hardier plants, and quality root mass - Chemical-free: micro organisms naturally improve soil over time, slowly releasing plant food organically - Complete trace elements and tertiary nutrients. Can safely be used in combination with all other soil amendments and fertilizers - Ingredients backed by government and university studies, as well as extensive field testing ## Images ![Blackwater Plus - Plant Growth Booster - Nutrients + Plant Hormones + Beneficial Microorganisms - Professional Grade (8oz Concentrate: Makes 8 Gallons) - Image 1](https://images-na.ssl-images-amazon.com/images/I/61JX1nal1UL.jpg) ![Blackwater Plus - Plant Growth Booster - Nutrients + Plant Hormones + Beneficial Microorganisms - Professional Grade (8oz Concentrate: Makes 8 Gallons) - Image 2](https://images-na.ssl-images-amazon.com/images/I/71s9ahd8-%2BL.jpg) ![Blackwater Plus - Plant Growth Booster - Nutrients + Plant Hormones + Beneficial Microorganisms - Professional Grade (8oz Concentrate: Makes 8 Gallons) - Image 3](https://images-na.ssl-images-amazon.com/images/I/71-hm89-DwL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Great for Cuttings! *by R***E on Reviewed in the United States on April 22, 2016* I grow a lot of fruit trees and bushes, or at least I try to. I have 2 grape vines, a blueberry bush, and a fig tree that I'm try to get cuttings off to bloom. Along with all that I have few random exotic flowers and plants I'm waiting to bloom, Before I used this food I managed to get a few measly bowls of tiny, sour blueberries and grapes once a year.The first thing I noticed about this is the liquid is actually black, I guess that's why it's called blackwater. Once you mix in a spoonful into a gallon it turns the water a dark purple color, like grape koolaid.One gallon was enough to water my blueberry bush, both my grape vines, 2 giant tulips, and a few of my fig tree cuttings.A few things I've noticed with my plants: More of my fig tree cuttings root. Normally I could only get a few here and there to root; when I used this most of them grew roots and are generally looking healthier.My giant tulip leaves are looking a little more shiny and dark. There's a few new leaves sprouting around it.My blueberry bush has grown a few new branches.I noticed no change in my grape vines.Overall it's helping my cuttings root, and my tulips healthier.I received this product for free in exchange for an unbiased review.Pros: Easy to mix and useWonderful for cuttings and flowersCons: Not sure it made much difference in my vines ### ⭐⭐⭐⭐⭐ My plants are greener and stronger! *by S***2 on Reviewed in the United States on April 14, 2016* My family love to start vegatables from seeds..a huge variety of tomatoes, cucumbers, etc. We have a plant light that has done an amazing job aiding the growth of these plants. But this year, I want to try to find an organic plant supplement. Seeing this from SunWheel, I had to give it a shot. The delivery was very fast and the packaging was great. I love that the product comes in a blackened out bottle to help preserve the nutrients in the liquid. It doesn't have an overwhelming bad odor, which is wonderful. I mixed the liquid as instructed and have been adding this to the plants that we have already sprouted. In one week, it is so easy to tell the difference! The plants are greener and the stalks have definately bulked up! I am so excited to have found this product...and its organic! I would certainly recommend this item and the seller! I did receive this item at a discount in return for my honest review. I was not guided on what to write in this review nor was I compensated in any form. 100% honest. ### ⭐⭐⭐⭐⭐ Gamechanger for me *by M***1 on Reviewed in the United States on March 29, 2016* Glad to see Amazon is selling this now. This stuff is like gold but REALLY hard to find. This plus fertilizer is about all I use now, and it took me awhile to narrow it down. Sometimes I wonder if other amendments are doing anything but the effect this has is obvious. One bottle lasts forever too, which is a refreshing change from other things out there. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/26201822-blackwater-plus-plant-growth-booster-nutrients-plant-hormones-beneficial-microorganisms](https://www.desertcart.jp/products/26201822-blackwater-plus-plant-growth-booster-nutrients-plant-hormones-beneficial-microorganisms) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-13*
