I bought a kit from the planet bong a Mexican variety full instructions are in the box the emphasis is on keeping the environment as sterile as possible what i did was covered the bottom of the tub in tin foil and placed that into a mop bucket (new ) and sterilized misted them with about 20 squirts its important that they receive some light from above so they know what way is up.....have a look at the Psyche/deli.com this was just a experiment
ps the kit cost £30 and the average yeild is approx 300 to 350 grams of shrooms
