    • Not Nutrient Agar
We learned the hard way this agar won't grow much of anything without adding some nutrients. After three experiments, with a total of 30 petri dishes, it grew nothing. We contacted our child's teacher who informed us we probably bought just the agar (gelatin). We used the remaining powder, seasoned with some bullion and sugar, and all 20 petri dishes grew fantastic colonies within a few days. The agar, itself, is actually of very good quality. It didn't dissolve in the incubator as regular gelatin did. I measured out five portions of 3 grams each which I mixed with 200ml of distilled water. This is enough to fill ten 80-100mm petri dishes with about 1.5 tablespoons of agar. Be sure to bring it to a boil, or it won't set. You could actually make the entire 15 gram package of agar with 1 liter of water and refrigerate the portion you didn't use. The agar will return to a liquid when heated. ... show more

    • A boss agar!
Was very easy to mix up an use in petri dishes. Very durable surface for inoculating - the gel doesn't tear easily.

    • Love it!
This was a great buy for my homeschooled children. It gave us a chance to do some fun science experiments and was very affordable. They had a lot of fun! There was enough to prep over 30 petri dishes with the first batch and I could probably get a second batch out of it. The only issue was taking the time to pull up metric conversion charts and guessing until I got the right combination to mix it up, but still worth it! ... show more

    • Great for a homeschool project
We purchased petri dishes that didn't include agar on accident so I bought this to correct my error. It was for a simply homeschool project on fermentation. The agar was easy to mix and set up nicely. I will buy it again for our next project!

    • Set up well, look good
Can't really comment on growth culture, ended up discarding dispatch due to some other problems. But it did set up well and looked like it was going to work.

    • Don’t be fooled by the name, nothing will grow in this unless you add nutrients
Not impressed. Nothing grew because after 5 days and no growth, we figured out we need nutrient agar. I added 1 t beef bouillon and 1 t sugar to 7.5 g (half the bag). Hopefully it grows stuff now.
