Can I use tap water for my microgreens?

Room temperature tap water is absolutely perfect for your microgreens, no need for filtering.  

There are however some things to consider:

• Very cold or very hot water can shock your plants, affecting their growth. Room temperature water is best.
• Avoid softened water, it can slow the growth of your plants. The Calcium and Magnesium in harder water is actually beneficial to your microgreens.
• Highly chlorinated water will have a negative impact on the growth of your microgreens, their appearance and taste.
