Wash your hands thoroughly and clean the outside of the grow kit with a clean, damp cloth. Remove the lid, but keep it for step 3.

Step 2
Fill the kit with water up to the edge of the kit (20 º C). Place the lid and let the mushroom growkit soak for 8 hours.

Step 3
After soaking, remove the lid of the grow kit and carefully pour off the water, until the last drop.

Step 4
Add warm water (20 º C) to the grow bag.

  • For the 1200cc grow kit: 2 cups (0.5 liters)
  • For the 250cc grow kit: 1 cup (0.25 liters)

Put the grow kit in the grow bag. Make sure the water does not go over the edge of the grow kit.

Step 5
Close the growing bag by folding the top of the bag and secure it with one or two paperclips (part of the grow kit package).

Step 6
Put the grow kit in a place out of direct sunlight but enough daylight, and not on or near a heater or heat source. The ideal temperature is between 20 and 25 º C. Make sure there is sufficient sunlight.

Vers nice immer wieder gerne
Evaluation: [out of 5 Stars]

Actually, I ordered 2 A+ Albinos and 2 B+ boxes. Unfortunately, A+ Albinos weren't in stock. After writing a short mail, Avalon immediately sent my desired GTs and B+. Shipping was completely okay, as fast as you expect it to be. However, I don't like those new(?) brackets which are supposed to keep the bag closed. For me, they were way too loose. I'm going to use the brackets from previous orders.

All in all, Avalon did a great job again. Unfortunately, the brackets are pretty crappy, that's why I'm going to rate this order a 4/5.

Including UK delivery it cost me about 165 euros , the "fast" delivery took over a week from the date they received my payment before I received my kits , within 48 hours of receiving them 2 out of 4 kits were mouldy , within 3 weeks the other two kits only produced about 4 mushrooms between them which all stalled , after this I gave up waiting and harvested what was there and put them in the fridge with water for another soak , this seems to ha e helped as one of the kits produced 2 pins within a couple of days and the other at least looks like it is doing something, I'll give it another 3 weeks and I'll come back with an update on what's happening with them.
I contacted Avalon almost a week ago now to see if they can sort this out before I post a review but I have heard nothing back from them.
Also only two out of the 4 kits I chose came, the other two were random strains I didn't choose .

Delivrely was fast as they promis, now after around ten days of waiting, all the boxes have mushroom growing well. It's not my first and i still follow the instructions to keep everything well. I will update after the first harvest to let you know how is going with the product of this supplier .
