Extreme XL Supa Gro Kit 100% - 'B+': exotic strain that produces magnificent shrooms

Supa Gro's Extreme XL Grow Kit 100% 'B+' contains a 2100ml brick of spore-inoculated substrate, mycelium of the Psilocybe Cubensis 'B+'. This fascinating magic mushroom strain is probably one of the most popular with hobby growers, due to the fact that it produces amazing, large fruit-bodies. On top of that, occasional nausea caused by mushroom trips is a rare occurrence with this strain. So, no need to worry, you will remain uplifted with this strain. The Supa Gro Kit will produce more than a couple of flushes. With just a little care, the average number of flushes is 5 – but there have even been reports of 7 flushes.

    A Good Start!
    Ordered my first ever grow kit on 6th May and it was shipped same day! Arrived 9 days later but that is due to reasons beyond Zamnesia's control so I won't be docking their rating. Grow kit is easy to setup as I received a very clear instruction manual on the day of ordering which explained the entire process plus the Zamnesia website has some very helpful info for the complete novice like myself. Now I will wait, tend to my babies once a day and see what magic awaits. Based on my experience so far I will definitely use Zamnesia again and rate them 4/5. I will happily adjust to 5 star rating if the grow kit delivers. P.S. I decided to start with the B+ because I read they're easy to grow, provide large flushes and a good trip. I look forward to the journey. C.L.

    Great flush. Better trip.
    Already got my first flush and got 500gr fresh mushrooms. Waiting for the next one. About their, I ate 4 gr and was the best one I've ever tried. Some laughs at the beginning and really mental mushrooms. 1 over 5 on visual. But it got my 5 over 5 on the trip.

    Just as expected
    I'd guess that anybody buying this would already have some experience with cultivating mushrooms, and I must say that you get pretty much what you expect. It may be more expensive than groving them from spores, but it's really worth not having to deal all the annoying stuff like mold contamination et cetera for that extra money. Just ventilate and spray it daily and you will have so much shrooms that you won't know what to do with them in a few weeks, but be patient, as sometimes it looks like nothing is happening and a few days later it just explodes with fruits :D. The first flush gave me around 200g of fresh mushrooms, the second one looks like it will do something similar or maybe even bigger, I hope that there will be a couple flushes more. As for the packaging and delivery, flawless as always.
