I have noticed recently that small areas of algae are appearing on my 8 weekly cleaned frames. Only some but not had it before.
Also the van roof had the same, cleaned about 6 weeks ago.
0ppm water.
Anybody know why? Thanks

Because it's been so wet.

Yep, wet, dark n cold, so ideal conditions for the growth.

Thanks guys, phew! Thought it might have been my hot water! (Joke)

[Splash & dash]

Damp , wet conditions = algi growth

[DeLuce]

Yep, soaked.
Plenty of rain, not much sunshine.
The ground is absolutely soaked through round here, north wales. I live on a farm, so used to what it’s normally like.
