Pet Grass is Wheat

What we are growing is hard red spring wheat. The same wheat we would use to make green smoothies for ourselves. You may see it sold as cat grass or pet grass but it’s just wheat harvested after a week of growth.

Wheatgrass is full of vitamins, minerals and amino acids. The juice has many health benefits due to the high concentration of chlorophyll, Vitamins B-12, B-6, K & C, and beta-carotene. I will say the juice smells and taste like freshly mowed grass.



Here is a video I made on planting pet grass in different mediums.


Buying and Preparing Pet Grass Seed

The best company that I have found is True Leaf. They have everything you need and the quality of the seeds and their prices are fantastic. They also offer free shipping on all orders over $45. I’d recommend looking at their micro greens sample kit which includes several varieties of vegetables. Once you learn how to grow pet grass you can grow most micro greens.

Depending on the size of the seed tray you use we need to weigh out our seed. For 10 x 21 standard tray I use 120 grams of seed.  Soak your wheat seeds for 12 hours in water and store in a cool dark location.

After 12 hours drain off the water and place the jar back in a dark spot for another 12 hours.

Your seeds will begin to sprout over the next 12 hours. Make sure the seeds don’t dry out during sprouting. Give the seeds another rinse off water.

Seed Trays & Soil

A few things to consider when choosing your seed trays are the size and quality. You are going to need 3 trays, one with holes on the bottom and two that are solid.

You can buy the standard 10 X 21 seed trays for around $1.50 a piece at Home Depot. They are cheap and easy to find but a real flimsy and sometimes you have to drill the holes yourself. You will need 120 grams of seed for this size tray.

I recently started using a 10 X 10 seed tray from Bootstrap Farmer. These trays are very sturdy and come with holes or without. I really like the size of these trays and it’s the perfect amount for one or two pets. 60 grams of seed works well for this size tray.

The potting soil or growing medium will be in the tray with the holes. We use the one solid tray as a bottom and this is how we water the seeds from the bottom. The other tray is placed on top of the seeds for the first 48 hours to keep the light out and it also helps keep the seeds in contact with the soil or paper towel.

Growing Medium Options For Pet Grass

  1. Peat moss/vermiculite mix is my favorite way to grow pet grass. The seeds germinate very well and the mixture holds moisture well. You only need to use a half inch of the mix and the roots of the wheat form a mat and there is very little mess when your dog or cat plays in the grass. The draw back is you need to buy two bags of product and mix them together.
  2. Paper Towels cheap and simple with very little mess are the reasons why I like using paper towels as a grow medium. The one disadvantage is they dry up very quick so you need to monitor that closely. Use a non bleached white paper towel. I use two paper towels on the bottom because it gives the roots more material to grow into.
  3. Potting Soil is easy to use and you can by a good mix at Home Depot or your local garden center.  It holds moisture well and it also provides the plants roots with vitamins and minerals. The only drawback is if your pet really digs and chews on the pet grass mat some soil is going to get on the floor.


It’s Planting Time

I’m using the 10 x 10 seed trays with an inch of 50% peat moss and 50% vermiculite. As you can see from the photo above you want to cover your growing medium with seeds. After you shake them out of the jar, use your finger to spread the seeds evenly and to get them down the sides and into the corners. You want the seeds to be in direct contact with the growing mix.

Then cover the seeds with a empty seed tray. We want to keep the light out and the cover on for 2 full days. On the third day you will remove the cover and expose them to light. The grass will be yellow at this point but will green up over the next 24 hours.

Pet Grass Lighting Options

  1. 3 foot LED light strip– These are inexpensive to buy around $12 and cheap to run. You don’t have to buy additional bulbs like you would with a fluorescent light. The wheat grass grows well and the bulbs produce very little heat.
  2. Fluorescent shop lights– if you have a spare set in the garage or find some cheap ones at a garage sale use them. The drawback is the price, around $20 for the fixture then you need to buy two light bulbs which can cost anywhere from $10 to $40 depending on the bulbs you buy. Fluorescent bulbs are also very fragile so be careful when installing them. I use them and the plants grow amazing under them.
  3. Windowsill or outside– Depending on the climate and the time of the year you could grow your pet grass outside or in a greenhouse. Growing outside exposes the grass to insects and different plant diseases. A sunny window sill would be a better option. The drawback is you can’t always depend on the sun to shine.


Watering and Harvesting Pet Grass

In the video below you will see how I stack my trays and water them. You will also see my set up I have in my basement. I’m uncovering the top and you will  see how I water them.
