First oyster mushroom grow!

I thought I'd share my first oyster mushroom grow. It's non sterile technique using paper pellets, lime water and G2 grain spawn. The bag weighs 1.8kg and is fed with oat bran. I'm quite surprised how fast these grow as this is just over 24 hours of growth. Anyway, I got a bit excited over this one. I'm looking forward to the feast.

Excellent! I took a print from a blue oyster that I put to Agar last week so I might try this method. I'd enjoy reading the entire process you followed. I have some familiarity with the "non-sterile" tek you followed - a friend told me if you place some of the fruit bodies in wet egg cartons the mycelium will run rampant. Your paper pellet method sounds similar. Now it makes me wonder why I am using Agar in the first place! Enjoy the feast.

I'd be happy to help! Here's a recipe for creating a mycelium run from stem butts.
Spawn Creation G1 Stem Tech for Oysters Paper Pellets: 1: Work out the total weight of substrate (water + pellets) you wish to prepare and then split that number 40% and 60%. The 40% figure will be the amount of paper pellets and the 60% figure will be the amount of water needed. For example: Total substrate weight is 2kgs this will be made up of 800g pellets and 1.2 litres of water. For G1 stem technique I recommend no more than 500g total substrate weight. 2. In a large bucket or tub measure out the amount of water required for your substrate preparation. Now add a minimum of two grams of hydrated lime per litre of water and stir until the water goes cloudy. This will raise the PH of the mix and act as an extra protection measure against mold development. To the hydrated lime water add the required amount of paper pellets and mix thoroughly until the water has been absorbed by the pellets. 3. Now it is time to add your chopped mushroom stem into the mix. A good handful of 1cm stem pieces per 500g mix is ideal. As an extra protection measure you may wish to dip your stem pieces into 3% hydrogen peroxide for 30 seconds or another option would be to cut the outer layer of the stem off and discard. Mix your clean, chopped stem through the prepared substrate and then place the mix into a bag or container. Make sure to add some breathing holes and cover with micropore tape to allow for gas exchange. 4. Place your completed g1 spawn bag somewhere out of the way, ideally within a temperature range of 18 to 25 degrees. After ten days it is time to remove the stem and add additional food. This is the point we will add bran or spent coffee to increase our yields. If using bran we want 5% of the substrate weight. For a 500g spawn bag we want to add between 25g of bran. To do this, add your desired amount of bran into a bucket, add a teaspoon of hydrated lime and 50% of the bran weight in water. Mix this all together and then break the colonized fruiting bag up, removing as much of the stem as possible, and mix through with the bran until it is evenly distributed through the paper pellets (To use spent coffee we just replace the bran with up to 25% of the spawn bag weight with spent coffee. For a 500g bag you can add up to a 125g of spent coffee, mix it through and rebag). Now you can add the mix back into the bag and put it back into its spot at between 18 & 25 degrees while it recolonizes. Once it has become a solid white block it is ready to expand. This should take a total of three to four weeks.

Here's a cheat sheet or quick guide for what you can do with your mycelium bags. You can also use upcycled containers to fruit in. I hope it helps!
STARTER CULTURE – First time around using grain spawn: NOTE: NO BRAN at this stage 600g kitty litter 900ml water plus half teaspoon lime 75g to 150g of grain spawn The higher the concentration of grain spawn the faster it runs and the less chance of mould. First time around using fresh mushroom: Trim back the outside and use pieces that haven't been exposed (or use hydrogen peroxide) 300g kitty litter 450ml water plus quarter teaspoon lime In other words, half of what you would use for grain. This bag will be half the size of your grain spawn bags. Check the instructions for details on removing the pieces and adding coffee or bran to grow up to a full bag. Now allow your starter culture to run. What would you like to do next? You have the choice of MULTIPLYING or FRUITING. TO FRUIT You will be adding bran, lime and water only (no additional kitty litter). One starter bag makes one fruiting bag. Bran is 10% of the weight of the bag plus a teaspoon of lime. Break up your starter and mix through the bran and lime. Add enough limed water for the mix to be squishy but not dripping. Put the mix back into your bag. You might have a bit left over and if you want to, you can use this to create another starter culture. TO MULTIPLY You have two options: The first is to prepare your starter culture in exactly the same way as you would a fruiting bag: one to one (as above). If you do this you will be able to divide the bag by ten once it runs. Your second option is to divide the starter culture directly into five fruiting bags. To do this, follow the instructions for making a starter culture bag and use one fifth of your starter culture instead of grain spawn. GOOD TO REMEMBER: Any bag that is white and solid can be used as either a fruiting bag or a multiplier. All bags (or buckets) need breathing holes covered with micropore. To fruit, place the bag where it gets plenty of light, humidity and air movement and spray with cool boiled water twice a day. Consider making a fruiting box. Once a bag has fruited you can rejuvenate it using exactly the same process that you used to turn a starter culture into a fruiting bag (one to one). Different mushrooms have different preferred temperature ranges. Some prefer sawdust or straw. Refer to the notes and cooperate with nature by growing the right mushrooms for the seasonal temperature. You can slow down growth by storing cultures in the fridge. If you don't want to create lots of bags at one time you can just take what you want to use and store the rest. If you time this well you can have a continuous supply of mushrooms.

The write up and cheat sheet are great! Looking forward to giving this a try, thanks for all the details. -LM-
