Maxicrop 1025 Soluble Powder, 10.7-Ounce

Good product

I'm a big fan of the 'black water' supplements. They seem to improve germination, and cut down on the fusarium. This is probably ten times cheaper than the liquid black water concentrate, if you go by colour density. I would also use this in my home-made hydroponic solution.

Works wonderfully on most of my plants. Have used this product for years….

I have tried different liquid organic Kelp products for foliar spraying with varying results. The Kelp companies I spoke with always claimed heat during transport and shelf life after opening were no problem, so why did my liquid kelp turn a different color, and others turned clumpy. This kelp powder eliminates my suspicion of contamination, reduced potency from heat during shipment, or spoilage after opening. It's a fine ground powder, 1 teaspoon per gallon of water, mix well, spray. Plants react favorably by 48 hours, pretty incredible. Thick, waxy plant leaves are more difficult to get a reaction from, I noticed more positive results when combining an organic nonionic surfactant and saturating leaf tops and bottoms during spray. I believe spraying in the cooler morning, an hour or more before the sun hits the plants is the best way to achieve maximum absorption before evaporation. Side note: my Summer enviroment is • Relative humidity 6-20 %, • 2,500 feet altitude, • frequent winds from 10-40+ miles per hour.

I diluted a small amount in water and put it in a clear plastic container I use for rooting cuttings. After several days I noticed small swimming creatures in the water. They look like mosquito larvae. Since the container is inside my house they had to have gotten there from the maxicrop. So, while I'm sure the plants love the nutrients I strongly recommend you do not make up a batch and let it sit unused for too long.
