Grow Kit FAQ

What makes your mushroom grow kit different from the other brands on Amazon or at the Big Box home improvement stores?

Our kits are of commercial mushroom growing size and quality, they are the same grow bags that we use at our farm to produce high quality gourmet mushrooms for fine dining restaurants all over Florida. They are made to order and timed properly. They don’t sit in a warehouse or stock room for months, we don’t use preservatives, and there’s no substrate soaking necessary. Our blocks are about 3 times the size and yield of other home kits.

We also include a built in humidity tent with the kit. This will ensure that your mushrooms won’t dry out and your kit will actually produce the mushrooms you’re expecting! It comes with a guarantee. If you’ve followed the instructions and you don’t get mushrooms, we’ll replace it and pay for shipping.


How many harvests and what yield will I get from the kit?

All of the kits will yield 2-4 lbs (sometimes more if you’re lucky) over the course of 2-4 harvests. Each harvest yields less and less until the organism has absorbed all of the nutrients from the substrate and converted them into mushrooms. Once the grow kit is “spent” it makes a great additive to soil for gardening. You may even get some mushrooms from your garden bed!


There is an orange-ish liquid developing inside the grow bag, is this normal?

Yes, that is metabolites. Its equivalent to mushroom “pee”. It's perfectly normal and won’t contaminate your mushrooms or affect the flavor in any way.


Its been 3 weeks and I still don’t have any mushrooms growing, what should I do?

Check your fruiting hole, it has likely dried out and the mushroom can’t work its way through the dry part of the substrate. Seal that hole up with tape, flip it over, and try again on the other side. Also make sure it is within the ideal temperature range and hasn’t died from being exposed to high temperatures. If the kit has foreign fungi or a foul odor, send us an email and we’ll let you know what’s up.


What is the growing medium?

We use the industry standard for high quality mushroom production. Its a recipe called “masters mix” coined by a grower out of Missouri. It is oak dust and soybean hulls. We use whole oats for the spawn.


Oops! I cut it on the wrong side, what now?

You’re fine! There’s no such thing as a “wrong side”. We say to cut it on the “top” side because that’s how it fits best within the humidity tent/box. Just keep it moist and humid and you’ll have mushrooms.


How should I store the mushrooms after harvesting?

Ideally, they prefer a paper bag in the fridge. A cardboard box or wrapping them loosely in a dish towel will work as well, just avoid solid plastic and non- breathable materials for storage.


My mushrooms don’t look exactly like the ones in the photo, what did I do wrong?

Likely nothing! Each cluster of mushrooms is unique, they come in many different shapes, sizes, and colors based on your growing conditions. For example blue oysters grown at 55 degrees will be dark indigo in color, but that same species grown at 75 degrees will be almost gray/white. Its super cool! You can even experiment with different conditions between each harvest by moving the kit to a different location in your home.


There is a patch of green mold in the grow bag, what should I do?

This happens, rarely, but it does happen. Foreign fungi enjoy the prime mushroom growing conditions that you're creating just at much as the chosen species does. Most of the time the organism in the bag will actually beat out the green patch. You can flip it over and place your cut on the opposite side of the green patch. It won’t result in contaminated mushrooms, don’t worry. If the green is taking over the whole bag, send us a photo and we’ll replace it for free.


Do I need to wash my homegrown mushrooms before cooking them?

No! Please do not do this, it makes the mushrooms waterlogged. Mushrooms grown indoors are free from things you would need to wash off of outdoor mushrooms. Simply brush off any substrate that may have found its way on to the shrooms.


Can I cut multiple holes in the substrate bag to produce more mushrooms at the same time?

Cutting extra fruiting holes in your block is an option and likely won’t ruin your kit, however it will produce the same yield split up between multiple clusters and have a better chance of drying out the substrate block, which is not a good thing!


How can I increase the chances of my mushroom continuing to grow after the first harvest?

The mushrooms will produce a second, third, fourth, even fifth harvest if you are good about keeping them moist and within the ideal temperature zone. The reason we suggest cutting such a small fruiting hole in the bag is to make sure you keep as much of that moisture within the bag.

If you see some baby mushrooms popping up for the second flush but they are trapped underneath the plastic, you can let them free and do your best to cover up/tape the original fruiting hole.
