16 cups of water, or 4 Liters, or 4000ml

Right before the veil breaks. Once the mushrooms break their veils, they stop producing psilocybin and start to produce spores. 

It depends. As long as the spawn bag is contamination-free, it can last for months. However, I recommend using them as soon as you get them for best results. Store them at 67F-70F. Just storing them in a tote works well.

Mushrooms don't contain chlorophyll. That means that during colonization, your spawn bag or bulk substrate doesn't require any light. The mycelium will colonize in complete darkness, but will also still grow with some light exposure. It is not necessary for them to be in complete darkness. 

During the fruiting stage, some indirect light can be helpful. 4-12 hours of light per day is sufficient. You can use an LED or CFL light, or place your monotub in indirect sunlight provided by a window. It is very important NOT to place the monotub in direct sunlight, as the heat from the sun will kill the mycelium. Remember, mycelium has a death temperature of 104°F (40°C).

Mushrooms grow best in a cool environment - but not too cold! 70 degrees Fahrenheit (21.1° Celsius) is an optimal temperature for colonization and fruiting. I typically keep a heater set at 70°F in the room, and this seems to yield good results during both stages.

If the temperature of the room in which you're growing drops below 65°F, then your mushrooms will grow very slowly, or possibly even stall. Avoid high heat as well: the mycelium has a death temperature of 104°F (40°C).

Keep in mind that the temperature inside your monotub will typically be a few degrees warmer than the room it's in.

Boomer Shroomer will accept returns within 30 days of purchase.

Please make sure your monotub holds air before using it. If there is a leak, email me within 30 days to get a replacement.
