General Hydroponics® pH Test KitGeneral Hydroponics pH Test Kits make pH testing easy. Simply fill a test tube halfway with nutrient, add a few drops of pH Test Indicator and observe the coloration of the liquid in the test vial. Many experienced growers prefer our pH Test Kit to expensive electronic meters because of its reliability and ease of use, which are important factors when the health of a valuable crop is at stake. Use 3 drops per 5ml of solution.

Things I’d prefer my children not repeat.
Format: Hardcover
My kids found it entertaining, but as a parent I was not thrilled with all the “poop” and “fart” jokes, as well as characters belittling and calling each other “stupid” and “butthead.”

Funny and clever
Format: Hardcover
Sashimi, a fish boy, is trying to find someone just like him. Instead he finds unlikely friends. The book is very funny and clever with just the right sense of humor for kids 2-100. I won my copy from a Goodreads giveaway. I will be sharing my copy with my grandchildren who will fall in love with Sashimi, too.
