White Cucumbers

I had 2 MiniMunch cucumber plants and as usual in Quadgrows.
Therefore water level & nutrition kept constant.
Had significant crop (and still doing so)
However after the few run of mini green cucumbers, had large numbers of white (or very pale yellow cucumbers.

What causes this ... is it a fertilisation issue (though Mini Munch are all female)

Never had this before.

 

Bizzare! Any chance of a picture?

Could be some disease or a spontaneous mutation. There are white cucumbers like Itachi. Are the cucumbers the same size and shape as the old ones, do they taste okay?

 

They are same size, also had some half green half white.
So a bit like Itachi

 

Whilst it's not unknown for named seeds to be of the wrong variety - even from reputable suppliers -it does sound rather odd if you are getting both both green and white on the same plant. Maybe it would be worth contacting your supplier ( with a photo if possible ) and see if other customers have reported a similar issue ?

 

Here is a pic .... green ones grow at same time as white ones on same plant

 

I also grow mini-munch.
I grow 1 a year in a 22L pot at the end of a row of tomatoes in my greenhouse and I get very pale ones like that if they've developed at the back of the pot which gets no direct sun and not a lot of light - all the others are normal

 

I was also wondering if it was lack of light. I have 2 mini munch plants this year, have also grown them before and never had any white ones. Interesting.

 

Ripe cucumbers are usually yellow or brown and hard so they may just be ripening early? or perhaps as you said they dont like being shaded.

 

Yes - that may well be the reason.
I hadn't thought of that, but you are quite right - fully ripe cucumbers do turn yellow and hard when fully ripened.
