XL Cylocybe Special MykoBox Grow Kit
£35.00
Used to be named "XL Cylocybe Special MykoBox Grow Kit", but a shop who first used the name for a different kind of grow kit has asked us not to use it.
This is still our same legendary kit that taught half the UK how to grow their first ever flush of mushrooms (and their second and third).
Enjoy.
- 0-3 working day dispatch. Order and pay before 1pm Monday to Thursday.

XXL Grow Tent
How do you use the tent?
Fold the top of the tent over, leaving a gap at one corner for top-FAE (Fresh Air Exchange), and tuck the piece of filter material we give you into that gap. It holds the gap open, helps keep the humidity in and keeps flies and dust out. Then watch your mushrooms and observe what they're telling you... Thin stems, "fuzzy feet"? Open the corner gap a little wider. Dry tent walls? Close it down a little. You observe and you adjust.
Perlite tips
We have always recommended draining the water off perlite before putting it into the tent. No change there, we still recommend it. But once the damp perlite is poured into the tent, we recommend pouring two cups of water in on top. The main reason is that it makes your life easier later, if things ever start to look dry then all you need to do is put your hand to the bottom and turn the damp perlite over so it sits on top. It's a real time saver. BUT, be extra careful not to touch your cakes. It likely won't be the cleanest water, so treat it that way. Extra brownie points for the customers who pour a little 3% hydrogen peroxide in every couple of days - a bottle of 12% goes a long way in this hobby when you are diluting it and I've found myself using it for everything from defeating cobweb mould to filling into a double tub incubator / fruiting chamber water reservoir where I have a fish tank heater set to 23C. We used to sell bottles of it on here, but they just weren't getting the sales - bonkers considering how useful it is. If you don't like the idea of putting excess water into the tent, we recommend cutting a corner at least so you can regularly pour water in and drain it. If you want to know how much humidity gets lost from your grow kit, consider weighing it each day and comparing with the last.
Advice
- This grow kit is tailored for large flush sizes.
- You don't need a SAB for this kit, but we still recommend using one for the inoculation stage.
- Typically 4-6 weeks at optimum conditions to fully colonise. Can't give exact times because it depends on species, whether live liquid culture or not, temps, genetics, mother nature.
- Colonisation temp of 23C (give or take a couple of degrees) for many popular species.
- Fruiting temp of around 21C (give or take) for many popular species.
Warning
If you live in a cold home, you need to build or buy an incubator. Don't use heatmats for the love of all things mushroom, we've seen countless people ruin this grow kit because they ignored us (then they go around sharing pictures as if it's the fault of the kit or even us) and it's extremely frustrating tbh. We put a lot of effort into our products, this is the premium you are paying for Cylocybe products and to waste it by not reading our guides isn't just a waste of your money, but it's a slap in the face to the time and effort that we put into our products. You wouldn't heat yourself up by standing on a hot frying pan. Don't listen to the other shops who sell kits like this, we are the OG with this injectable kit... Our guide will keep you right.

Overall really happy with the product. Very easy to use. Really sterile and no problems with contamination. The mycelium took a little longer to fully colonise the box than I expected, but that could have possibly been down to temp fluctuations in my incubator. I would DEFINITELY recommend this product! 10/10
