Plant Revolution Orca Premium Liquid Mycorrhizae 32 Ounce, 1 quart/32 oz. Fertilizer

It's good, works well. I like it and will continue to use it.

Anyone growing hydroponically has probably encountered "root slime." It appears as a clear or brownish mucus-looking substance on the roots of plants. It's commonly called brown slime algae, which actually isn't algae at all, but a cyanobacteria. This will coat the roots, keeping them from breathing or absorbing nutrients. The roots then die and rot, killing the plant. I grow cannabis for medical purposes and I've used many things to try to control the root slime. While some types of compost tea will work wonders, this product is much easier to use. It works fast and I have used it to cure root slime if I catch it early. As a preventative it really does the job. I've never had root slime start in a reservoir containing Orca. This was the last product I tried because I put off purchasing it. It is a little pricey. However, I wish I just would have used this first as it is easy and effective. It may be expensive, but it goes a long ways. When I use it as a preventative, I use only half of a ml per gallon, so a quart (947 ml) will treat almost 1900 gallons of water. The price of treatment per gallon then is less than 3 cents. That's a very inexpensive cure for a very costly problem. While there are much cheaper methods of treating root slime, I've not seen one more convenient than Orca.

Always one of my go to plant products!

Definitely recommend for hydro. A little spendy, but worth it. Keeps the roots nice and white.

Should have got the powder lol. This stuff is messy.
