Review: Hard to tell yet, but seems to have substantial benefits - I used this in my vegetable garden (and in some container plants) just a week ago, so I really can't tell what the results are yet, but it does seem to have perked things up a bit. I had an impatient basket that was looking a bit sickly and after giving it seaweed, it seemed healthier within about 24 hours. (I think the soil in that pot was very nutrient deficient.) I also noticed that my tomato plants seemed more "alert" if that's a good description--more vigorous, I guess. But, as said. I did put it on all sorts of plants in my garden--tomatoes, cucumbers, zucchini, pumpkins, herbs, etc. and I don't know if it's my imagination or not, but the plants seem a bit healthier looking. I also emailed Maxicrop to ask if it was safe from vegetables because there is a small sticker on the bottle that says not for agricultural/food use. But I was assured it was safe and that the label was a part of an exhaustive process that plant-fertilizer manufacturers are put through for organic certification and other reasons and that adding that label is a requirement of the on-going process. The company was very responsive and told me that they're trying to get more product information on their desertcart pages. I'm satisfied that this entirely safe for food/vegetable and fruit crops. I have met farmers in Bermuda and Maine that swear by seaweed. In Bermuda I met a gentleman that had a small banana farm near the beach and he told me that he went down and raked seaweed regularly. When I asked him why he smiled and said, "Don't you use seaweed in your gardens? You should!" He then spent an hour showing me how he gathered it, dried it and mulched it. (I love the people in Bermuda.) There are so many variables in a home vegetable garden (soil, sunlight, watering), it's impossible to know exactly what benefit a certain product has, but I'm convinced that a healthy organic garden is dependent on a rich and broad source of micronutrients and this product from Maxicrop seems to be the answer to that. I'm also going to start using fish emulsion for the first time. There is a bumper sticker around here, from an organic farm, that reads, "Be good to the Earth and the Earth will be good to you." I couldn't agree more. I'll update this when I've used it a few more times (I'm going to use it weekly, one capful per gallon). In the meantime, based on Maxicrop's fast and detail responses and the immediate improvement in some of my plants, I'll give this five stars. Review: Recommended to me by David Austin customer service - I started using this by recommendation from David Austin after having problems with one of my Olivia Rose Austins. It works amazing! I saw new growth within a couple days, no exaggeration. It helps with transplant shock on new transplants and as I was told helps "spindly plants" with cell wall growth. Not just for my roses but my Rose of Sharon is notoriously late to break dormancy where I live, and it's actually leafing out in late April! I use it consistently now with fish fertilizer and another product for blooms. What a difference. Great product! ## Features - Pure seaweed extract’s initiate cell growth and vigorous root and stem growth - Trace elements that Maxi crop Liquid Seaweed contains are important as activators of enzyme systems - Maxi Crop's basic is a pure 100% seaweed extract ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000COBUQC | | Best Sellers Rank | #27,737 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #856 in Garden Fertilizers | | Brand Name | Maxicrop | | Coverage | Medium | | Customer Reviews | 4.7 4.7 out of 5 stars (1,112) | | Global Trade Identification Number | 00755361010051 | | Included Components | Fertilizer | | Item Form | Liquid | | Item Weight | 2.2 Pounds | | Liquid Volume | 32 Fluid Ounces | | Manufacturer | Hydrofarm, Inc. | | Mixing Ratio | 1:128 | | Model Number | MCORGQT | | Specific Uses For Product | Plant growth and health promotion, including propagation | | Target Species | plants | | UPC | 755361010051 | | Unit Count | 32.0 Fluid Ounces | ## Product Details - **Brand:** Maxicrop - **Item Form:** Liquid - **Item Weight:** 2.2 Pounds - **Liquid Volume:** 32 Fluid Ounces - **Specific Uses For Product:** Plant growth and health promotion, including propagation ## Images ![Liquid Seaweed (Kelp Extract, 32 Oz - Image 1](https://m.media-amazon.com/images/I/81-R91p-DrL.jpg) ## Questions & Answers **Q: What is N-P-K rating?** A: The N-P-K rating lists the relative amounts of Nitrogen (N); Phosphorus (P) and Calcium (K) in the product. This is a common measurement in plant fertilizers. The N-P-K rating of this product is 0-0-1. **Q: Can I use this in a Aquaponics set up?** A: Yes indeed. It's great as a starter for your plants as your system cycles. Just a cap full once a week did it for me. I have 100 gallons total water in my system. 20 gallons in my fish tank, 20 gallons in my growbed, and 40 gallon sump tank. I also use it regularly about twice a month- a cap full. Don't worry that the water turns tea-like in color for a day or to. Also, consider using the MaziCrop with iron if you have PH issues and see your leaves are turning yellow. **Q: Is it organic? Will this work well for Citrus trees in pots? Any idea what all the minerals and in what amounts are in this product? Thanks** A: I don't know if this helps but I use it in my garden and on my citrus trees and I live in Florida as for the other questions I don't know maybe Google the product. It works great tho. **Q: when they say 1 oz per gallon, how much do you actually give the plant? Sorry, I am a bit OCD. Seems you could give them a cup, quart or gallon** A: What I meant was 1 oz. of Liquid Seaweed added to a gallon of water, or 1 part Liquid Seaweed to 128 parts of water. Whatever amount of water you would normally give to your plant is what you would with this mix. ANY plant in a pot should always have fertilizer with each watering, there is no nutrients in potting mix like in the ground that plants feed on. Hope this answers your question. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Hard to tell yet, but seems to have substantial benefits *by J***L on July 22, 2015* I used this in my vegetable garden (and in some container plants) just a week ago, so I really can't tell what the results are yet, but it does seem to have perked things up a bit.
