I was gonna say that after seeing that photo posted by whoever that I went to go get some to try out.
I got one bag for about £4.50 but when I came to use it (weeks later) there was only enough in the pack to use half a dose on each plant in my pot size (8L) and I haven't been able to find any more in 3 different Wilkos (my grow shop now gets it for cheaper so no bother).
So I used it on these 8 Exo/Psycho I have for the next round and it seems to be brilliant stuff.
I potted the clones up with the myco about 6 weeks ago, I got some Biobizz Grow to go along with my synthetic nutes to feed the myco specifically.
In the last 6 weeks the plants have only been fed twice and are so healthy and taking up nutrition so well that the N in the Biobizz is borderline burning them.
I'll get a photo up later, they look lush.
