Varieties in the XL range

All grow kits on this page are 2100cc variants, yielding up to 800 grams fresh per kit over multiple flushes. The strains do not differ in cultivation method, but they do differ in their effect profile and ease of cultivation. The Golden Teacher is one of the most commonly used starter strains, offering calm and clear experiences with little risk of overwhelming effects. The McKennaii is significantly more intense, with a more cerebral character and stronger visual effects, making it more suitable for those with prior experience. The B+ is known for its robust growth and broad effect profile, and is well-suited for a second or third grow cycle. Mexican and Thai are classics with energetic and cheerful effects, while the Mazatapec is somewhat calmer and more introspective. PES Hawaiian and Treasure Coast are among the more potent strains in this assortment and are less suitable for a very first experience.

Shelf life of the fresh magic mushrooms

The XL magic mushroom grow kits yield large quantities of mushrooms for use. The 2100cc variant yields up to 800 grams of magic mushrooms.

You can store fresh magic mushrooms in the refrigerator for a short time, up to about 10 days. If you want to store them for a longer period, dry them and keep them in a dark, dry place. They will usually last for months. You can read more about the right time to harvest in the knowledge base article on picking magic mushrooms.

Frequently Asked Questions About XL Magic Mushroom Grow Kits

How long does it take before an XL grow kit is ready for the first harvest?

With a 2100cc XL grow kit, it takes an average of 1 to 2 weeks after soaking before the first pinheads are visible. After that, the magic mushrooms grow rapidly, and you can usually harvest within 5 to 7 days after the first pinheads appear. The total turnaround time from the first soak to the first harvest is usually between 10 and 20 days, depending on the strain and room temperature.

How many flushes does an XL magic mushroom grow kit yield?

Most XL kits yield two to three flushes. The first flush is often the largest. After each harvest, soak the substrate again for 12 hours to stimulate the next flush. By the third flush, the yield decreases noticeably, but for most users, it is still profitable.

What is the ideal temperature for growing magic mushrooms?

Most strains in this assortment grow best at a temperature between 23 and 26 degrees Celsius. Too cold significantly slows growth; too warm increases the risk of contamination. Avoid direct sunlight on the kit. A constant room temperature works better than large fluctuations.

Can I save an XL magic mushroom grow kit for later use?

That is not recommended. As soon as you receive the kit, it’s best to set it up immediately. You can store it in the refrigerator for up to 1 to 2 days, but the longer you wait, the greater the risk of a reduced yield or contamination. Planning your order for a time when you can get started right away is the smartest approach.

Which type of magic mushroom grow kit is best for beginners?

The Golden Teacher XL and the Cambodian XL are the most accessible choices. The Golden Teacher is known for its forgiving cultivation profile and mellow effects. The Cambodian is less susceptible to contamination, making it a good option if you have little experience with sterile cultivation. Be sure to read the blog for practical experiences and tips from other growers.

What is the difference between an XL grow kit and a medium grow kit?

The main difference lies in the volume of the substrate. The XL kits contain 2100cc of mycelium, compared to 1200cc in the medium version. This results in larger harvests per flush.
