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.

Supa Gro magic mushroom grow kits are grown by mycological experts and contain extremely healthy mycelium.

    Didn’t work but zamnesia sent another
    My grow kit unfortunately did not sprout anything but fortunately a Zamnesia did send another. I’ve since moved it to a monotub and havinf some better results for it coming back to life a bit


    Biggest harvest ever
    I'm on my 3rd flush right now!


    Loving this one
    Best yield ive had from a growkit


    B+ XL
    Five flushes in great quality. Try it :)


    Le début...
    Pour l'instant ce n'est que le début j'ai récolté quelques champi qui font presque 20g frais. La qualité est au rendez-vous.


    Above expectation
    This kit cut off a lot of risks of contamination and makes all easy and fast. The smart idea of using the cardboard box to prevent the lateral growing is smart and easy. Vg quality Thanks again


    Amazing Box
    I am pretty new in this business, but this Box! I had GT and B+ from XL Supa Gro and they where both fine. B+ first flush exploded with over 250g and second around 100 less.


    Very good kit for now
    Everything good for now. I had my first flush aroung a hundred or more grams. Let's see what we get next ! :)


    big disappointment
    Got only 7 mushrooms on the first start which were very small. no more mushrooms came, but the box was restarted.


    Extreme XL Supa Gro Kit 100% 'B+'
    Livraison très raisonnable dans ce contexte. Bon produit avec une belle productivité...
