How do I determine the correct dosage of Bloom Silica for my growth medium?

The dosage of Bloom Silica depends on the growth medium you're using. In general, use less for recirculating hydroponics and potting soil systems, and a full dose for run-to-waste hydroponics. There are specific application rates listed for recirculating, soil, and run-to-waste systems.

What should I do if my nutrient solution becomes cloudy or milky after adding Bloom Silica?

If your nutrient solution turns milky or cloudy after adding Bloom Silica, it indicates that one or more of your nutrients are reacting. Ideally, discard the mix and start again. Use less Bloom Silica next time you make your nutrient solution.

Depending on the growth medium, a 1L bottle of Bloom Silica can make the following amounts of nutrient solution:
