Hydrogen peroxide (H2O2) is valuable in mushroom cultivation due to its antimicrobial properties and for its ability to sterilize substrates without excessive heat. H2O2 selectively eliminates bacteria, mold spores, and other competing fungi while leaving mushroom mycelia unharmed. It helps prevent Trichoderma (green mold) and other contaminants from growing & is a simple & cost effective cultivation enhancement where steam sterilization or autoclaving isn’t available.
H2O2 has additional benefits because it degrades naturally to release oxygen which aids mycelial respiration and growth. This effectively pasteurizes substrates which inhibiting anaerobic bacterial contamination and reduces the chances of contamination before inoculation.
All Indigo® hydrogen peroxide test strips have a 3 year minimum guaranteed shelf life & come with a Certificate of Analysis, Stability & SDS documents listed below; Certificate of Conformance on request. Be prepared for any health & safety audit or inspection.
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.

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!
