Growing Hydroponic Sage


Sage is another wonderful herb to grow in your hydroponic system.  Sage is described as having a taste that includes pine, mint, citrus and even eucalyptus flavors.  It has a strong aroma, so you don’t have to plant much to take advantage of its wonderful taste.  However, germination of sage can be quite slow, taking 7-21 days for a seed to produce.  While sage grows more quickly in hydroponics than in soil, it tends to be a slow grower either way, so consider some sage advice and perhaps propagate your sage from a cutting, rather than starting from seed.

Sage is slow to germinate, so don’t get discouraged if it takes 7-21 days for your seeds to begin growing.  Remember, you can always speed things up by using our Seedling Starter Kit or the paper towel method increase the rate and speed of germination.


Sage is an herb that likes lots of light, so run your hydroponic systems lights for 14-16 hours a day.  Because sage is a slow grower, this will also help it grow more quickly in the early months.

EC Range:

Sage grows best in an EC range between 1.0 – 1.6.  It will produce well with rosemary, basil, lettuce, strawberries, peas, dill and thyme in your hydroponic system.

pH Range:

For best results, keep your pH range between 5.5 – 6.0.  If you have other plants that prefer a higher pH range feel free to increase it just a bit, and you should still have success!


Just like other herbs, lettuces and greens, sage will grow great with our Green Machine nutrients.  You won’t have to worry about adding anything special for your dill plants to thrive once they start growing.

Time to Harvest:

Sage is a slow grower, so give it time to find its roots before harvesting.  Initial leaves will come up relatively quickly after propagation, but it slows down after that.  Give your plant time to grow before harvesting.  It will become bushy over time, with woody stems.  If you’re impatient, consider propagating sage from a mature cutting, rather than starting from seed.  This will allow your sage to mature more quickly.

Pruning and Harvesting:

Because sage grows slowly, remember to prune your sage lightly until it becomes stronger and able to grow more profusely.  Once this occurs, trim off leaves and stems as desired.


While sage is slow to grow, it’s strong flavors and aroma mean that a little will go a long way in dishes and seasoning blends.  Enjoy growing this flavorful and versatile herb in your indoor garden!
