Nutrient and Health Info - Thyme has healthy amounts of Vitamin A and K. It is also known to have anit-infamatory, antimcrobial and anitseptic properties.
Tips & Tricks - Thyme can be dificult to germinate. Be patient, and use 3 seeds per pod. Sow them shallowly, because they are so small. Use Thyme on meats, in stews, teas and on potatoes. It is also sometimes used by some as a salt substitute.


Thyme, thyme, thyme, is on your side.  Yes it is!

It’s true…Thyme is on your side.  That’s because thyme is known for its anti-inflammatory, antimicrobial and antiseptic properties.  It also contains healthy amounts of Vitamins A and K, and is used by some as a substitute for salt.


Thyme can be difficult to germinate.  It’s a great candidate for the Seedling Starter Kitthe ‘paper towel’ method, or making your own seedling starter kit with Tupperware and plastic wrap with holes poked in the top. 

When growing thyme directly in your media, be plant at least 3 seeds in each pod so that one is more likely to sprout.  The seeds are tiny, so plant them closer to the surface to give them the greatest chance of successfully germinating and growing.

Some people prefer to grow thyme from a cutting.  Stick your cutting into a small glass of water with two drops of willow bark extract to help it root, prior to placing it in your garden.


Thyme will prefer to grow with 14-16 hours of light.

EC Range:

Keep your hydroponic garden’s EC range between 0.8 – 1.6 for best results.  Fortunately, this range is compatible with growing a number of other plants such as basil, lettuce, strawberries, peas and spinach.

pH Range:

Keep the pH of your thyme between 5.5 and 7.0. The right pH level ensures that plants absorb the nutrients they need for optimal growth.


Thyme will be grown best with our Green Machine nutrient mix.  Mix your nutrient solution thoroughly until your EC meter reads 0.8 – 1.6.  Thyme will bolt (grow flowers) over time.  The flowers can be beautiful colors of purple, white and pink, and are even used in bouquets. But, as usual, when herbs flower, the taste of your herb will suffer.  Keeping your EC within the range of 0.8 – 1.6 will prevent flowering.  If you see flower buds forming, clip them if you want to maintain the plants taste.


Prune off brown leaves as needed.  If there are significant amounts of brown leaves, confirm your EC and pH is within the recommended levels. 


Thyme grows to have thick, bark-like branches. You’ll want to use clean, sharp scissors or shears for harvesting. Make sure to leave plenty of plant material to regrow when you harvest. 

One more thing…thyme lasts a long time.  It will often grow for 2-3 years, but eventually the branches become very thick and woody.  That’s when it’s time to grow a new batch.
