which creates a growing surface area of 466 m2 on five levels. The trays are sprayed by a system that runs via cables attached to the ceiling, and picking platforms are used to harvest the mushrooms. The only thing done by hand is ruffling, which is behind the affiliated growers’ request to perform this task centrally. The yield was 29 kg/m2 in three flushes.
Later on in the day we saw the packing station where all the fresh mushrooms and exotics are packed and distributed. To conclude, what we saw was a very impressive, well-organised company that, thanks to a programme of investments in quality, has taken a prominent role in mushroom growing in Spain, and sees a future in expansion.
Coseman
On Friday morning we visited Coseman, an oyster mushroom substrate company. This is also a cooperative comprising 110 growers/ partners, of whom 50 grow on a very limited scale. This plant was constructed in 2000 and produces 800 tons of oyster mushroom substrate (phase II) per week for its members. The process here was identical to the description in the previous article, and there was also a bio wood boiler on site to generate steam, but this time not powered by wooden pallets but ground olive

stones. The blocks are also pressed using the same type of machines as we described earlier. Afterwards we visited several smaller growers you have equipped rooms all over their buildings to grow oyster mushrooms. There was very little in the way of climate control to be seen, so growers are highly dependent on outside weather conditions. This makes the supply and prices of oyster mushrooms very unstable.
Later in the afternoon we continued on our way to Madrid, from where we all parted company or enjoyed an extra day discovering the fascinating Spanish capital. It was an enjoyable and educati- onal HLP trip in a beautiful, friendly and hospitable country!
