Sterilize mushroom bulk substrate growth media with accurately diluted drug store grade (3%) H2O2 to optimize its antimicrobial properties. Indigo® 100ppm hydrogen peroxide test strips are easy to use whether you are a beginner or commercial cultivator.

Eliminating competitor spores & bacteria to support mushroom mycelial growth. If higher concentrations of peroxide are needed, try our 0-10000 hydrogen peroxide test strips. If you are using bulk pellet fuel substrates the 0-400ppm hydrogen peroxide test strips may be what you need.

Use our hydrogen peroxide dilution calculator to reduce food grade peroxide to the 100ppm range.


Petri dishes can hold your agar culture growing medium for mold spore germination; they're sterile & inexpensive. Your interest in mushrooms, besides beyond growing for fun or profit, might be aided by a geology hand lens. Read our two blogs on magnifiers & mushrooms.

We started using H2O2 in our swimming pool These test strips help us to keep the levels accurate. Easy to use and easy to read. Very happy with the product and with the results in our pool!

Perfect to balance H2O2 in hot tub.

Good to know. Some of the hot tub vendors who have contacted us over the years recommend the 400ppm hydrogen peroxide strips. Both are effective but outdoor hot tubs may be more susceptible to windblown algae as well as H2O2 breakdown due to sunlight.

Excellent product , very east to read and quick results! Arrived sooner then expected!

Easy online ordering. Was ready for pick up in no time. Have always used these test strips from Indigo for testing my hot tub. They work great and are reasonably priced.

Product works good, price seems reasonable. However, they didn't do what they said they would do for shipping. The site said orders before 11am shipped same day. My order was after 11am but, i felt it should be shipped next day which did not happen. It was handled as an order that came in after 11am the next day & then there was one more extra day delay for 'power outage'...disappointing!

— Indigo: Sorry about that, have rewritten the guarantee. At least the product worked well!
Very fast shipping, good order accuracy. The test strips are a cost effective way to accurately manage residual H2O2 levels.

Great service; price and product. Canada Post dropped the ball. Paid extra for express post and package sat in Canada Post for 3 days then delivered on day 4.

— Indigo:

Thanks for the feedback. Many of our Canadian customers have had similar problems. This prompted us to write: Canada Post is in the way of small business competing against Amazon.


Great friendly service , always helpful and h202 strips high quality
