Telepathy F1 cucumbers

Im new to the greenhouse club this year after wanting one for many years. Getting back to the cucumbers, I bought one packet of Telepathy F1 from Wilko for £1.60 and Im so impressed with the growth of these in my quadgrow system. The taste as expected is so much better than the shop bought ones and one plant seems to give you many cucumbers. I've found the skins go more tougher when left to go bigger, but I like them both. Harder skin gives a lovely crunch.
