Neptune's Harvest Crab & Lobster Shell, 4 lb

Love neptunes harvest products for my garden. This stuff stinks but is tolerable. I mix it in the soil before planting my veggies in the spring and it does wonders to the soil to help feed my plants.

This has made a fantastic addition to my organic soil mix.

Fair price, allegedly all natural fertilizer. I suggest adding it when preparing the soil with other natural fertilizers. Takes time to break down.

Works great for tomatoes and peppers

I could have gone to red lobster and had a meal to get chitin based shells from Lobster, crab or shrimp, but alas it was cheaper to come here. I bought 250mg of chitin suitable for chitinase activity from Sigma-Aldrich, but ohhh hey no information on how to solubilize the material, but lucky me it had a useless MSDS. Good thing it cost only 60 bucks for 250mg......WHHAAATTT. Then I found that I can make it by dissolving 20 grams of ground up shell in 150ml of 12N hydrochloric acid to break them down into colloidal chitin and then wash it with copious amounts of double distilled water a day later. Some people just want to watch the world burn, way to go Sigma-Aldrich. I need to make colloidal Chitin to test bacteria for the utilization by the enzyme chitinase. Chitin is a glucose derivative with an amine group in long chains (Beta 1-4). I Why not right? Chitin, Calcium and Magnesium in one shell, works for my needs. The longer I am in science, the more I realize the margins for chemical companies makes the food industry look like homeless people. Assuming I have a 75% loss of starting Chitin (100%=1814 grams), I still get 453 grams of colloidal chitin for the same dam price as 250mg. If I paid sigma-Aldrich, it would probably run (assuming 50% of the cost) 45,000 dollars. This would be akin to me making 100ml of DNA taq polymerase for 200 dollars in the lab versus if I bought it would cost 120 dollars for 100ul or about 120,000 dollars. The lesson here kids is...learn chemistry.
