We currently have six guinea pigs in our guinea pig cages, and we are always looking for ways to have fun with our piggies.  We decided to buy some sprouting trays and seeds, which are an easy way to provide fresh grass. In the warmer months, we let our guinea pigs safely graze on untreated grass, but in the cooler months, we like to give them fresh grass as well.

If you have guinea pigs, you know how excited they get over fresh greens! It is good for them to have a varied diet, including good quality guinea pig pellets, hay, and fresh greens. Check out my post about what to feed your guinea pigs.

The benefit of growing grass indoors is that you don’t have to worry about a lot of factors that you would deal with outdoors.  Outdoor grazing comes with a lot of hazards, such as predators (hawks, cats, owls, etc), chemicals on grass and soil, possibility of being exposed to parasites, accidentally eating plants that are toxic, and more.

Growing grass indoors in trays is actually very easy.

The first thing you need are some sprouting trays.  We got ours on Amazon.

Next, you need grass seeds.

We have grown wheatgrass seeds many times, and a 1 lb bag will last you several growings.

The recommendation on the bag says to soak the seeds 8-10 hours.

After that, we spread the seeds on the tray.  At the beginning of the seed sprouting process, we keep the seed tray in a shaded location inside. (It is later that we move it into a sunny area).

The tray comes with a clear lid, and we mist the seeds every day with a mister, to keep the seeds moist.

Tip: you can usually find cheap spray bottles at the dollar store.

Within about a week, you will see the grass sprouting.  Once the seeds begin to sprout and the grass turns green, I don’t keep the lid on, and I move the tray to a brighter location.  We have seen mold growing on the roots if there is too much humidity (to be expected).

We clip the grass for the piggies so that we can portion it out, and since the guinea pigs usually yank on the grass as they graze.  (It also gives the kids something to do!).

The guinea pigs love their grass!

So this is our experience growing wheatgrass in trays, but be sure to follow the packaging instructions and tweak the process however it best works for you.

You can also grow grasses in a tray of soil. Using a tray without soil is just one method.

Happy growing!
