A larger pressure cooker simply fits more jars - sure a smaller pressure cooker is fine. Depending on availability, you can buy medical grade cotton which is sterile. Microwaving the substrate (very high temperatures killing everything) will sterilise it, which is better than nothing, but will be more susceptible to contamination than pasteurisation.
Thanks for the encouragement!
A week after your substrate is fully colonised you should start to see some pinning. In nature you get a drop in temperature with Spring rains, so you can sometimes (depending on your variety) place your substrate in a cooler area and then bring them back after pins start forming. Test your substrate is fully colonised and all smell the bags (healthy bags should smell sweet).
Surinder,Oysters fruiting conditions are basically warm weather and moisture exchange. I have never tried to delay fruiting but you should be able to refrigerate (around 4 degrees) and wrap to delay pinning. Sometimes in nature, mushroom fruiting will be delayed by a month due to the colder conditions... obviously it is best to allow fruiting for best yields, delaying may lead to less vibrant growth and so lower crop yields... do some experiments and let us know how you get on.
Hey Jen, yes you are right, however the key to a healthy uncontaminated culture is to reduce the exposure time during spore transfer. If you are simply transferring from a spore print, the time the agar is at risk of contaminants can be minimized. Or at least that's the idea, you can always experiment to see what works for you.
Hi there, I would say for the growing medium (straw), that boiling would be ok, but with soaking first and draining, then heating/steaming, it is all ready to go for inoculation with less chance of contamination. The medium should not be dry (gravity draining is fine). Equally, with seed and spawn propagation, I would suggest it should be drained then steamed to create less chances for contamination.But really, you can try different things and let us know how you go, it's all a learning experience. :) All the best!
Sorry I can't help you much here, it really depends on the country where you live. Have a look on the web for others growing in your area, perhaps a forum and ask there.
Hi there... Regarding lighting, I have never grown in artificial light but I would recommend 12hrs on 12 hrs off, much like nature provides. Hope you have great success!
Another way to increase oxygen to the mushrooms is to leave the substrate in the growing bags but make 2cm x-cuts at intervals around the bag. This will promote pinning in those areas and improve yeild consistancy.
Another way to increase oxygen to the mushrooms is to leave them in the growing bags but make 2cm cross cuts at intervals around the bag. This will promote pinning in those areas.
Sounds great... if you remember post some pictures.
Ineffective straw sterilisation can allow other fungi and moulds to grow in the substrate leading to contamination. If you are noticing sprouting grass from your substrate look out for unusual varieties of fungi. Although I wouldn't recommend eating them, ink caps can actually be eaten, but like their colloquial name (tippler's bane) suggests, they react with alcohol giving you a 4-5 day hangover.

Oyster mushrooms can actually grow in salt water. In a trial testing the ability of oyster mushroom mycelia to break down hydrocarbons, Paul Stamets (world-renowned expert in mushrooms and other fungi) noted that oyster mushrooms grew at a rate of 75% in salt water. So, it appears that it shouldn't be too detrimental to use your water with a slightly higher salinity.
Thanks for your attractive hammock wall mount... it's just brilliant! I know how difficult it is to find suitable wall mounting hardware, as I have recently mounted an indoor hammock myself. In the end I used a gate hinge fitting with coach bolts going entirely through the block wall. I then attached a chunky D shackle to connect a carabiner to, making it easy to pack away (into a wall cupboard at one end). Anyway, great job and thanks for sharing!
Great job. Thanks for sharing!
