How to make sterile mushroom culture substrate?
An important step in your mushroom spawn culture procedure is to ensure your bulk substrate is free of microbial contamination & can support mushroom mycelium growth. Low concentration hydrogen peroxide can ensure the best oyster or shiitake mushroom substrate by limiting fungus infection during mushroom cultivation. Use Indigo® 100ppm hydrogen peroxide test strips whether you are a beginner growing mushrooms at home or for sale of edible commercial mushrooms,
Use petri dishes for spore germination; they're sterile & inexpensive. If your interest in mushrooms extends beyond growing for profit, you may also find that a geology hand lens is helpful out in the wild. Read our two blogs on magnifiers & mushrooms.
The number of strips per vial (100) is approximate.
Suitable for detection of hydroperoxides and ether peroxides. Polymeric peroxides, which can form in diethylether, are not detected.Organic peroxides, such as di-terc-butyl peroxide, di-cumyl peroxide or terc-butyl perbenzoate, either do not react or react with significantly reduced sensitivity.
Indigo® brand hydrogen test strips are Made in USA & tested for accuracy using NIST compliant standards.

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.

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!

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.
