Cool Cucumbers For Hot Houses

Back in February I sowed my cucumbers and gherkins, now in May they get planted. I sowed two Beth Alpha cucumbers which are for greenhouse growing only. They are six inch sweet fruits which I harvest one of daily. Two plants give us all we need.
The gherkins, I sowed three of Piccolo Di Parigi and two Cornichons de Paris. All are now planted upon the staging in ring culture pots and growbags. I find this method works well for me. I then grow up strings attached to the high shelf above, once they reach that far, all seedlings will be off the shelf and planted out. Three cucumber plants of Boothbys Blonde will go out into the allotment later.
