Hylocereus issues

[christ_hears]

Team!
Can someone explain why the thorns on my hylocereus are so large? Also, I overwinter in a basement with no light and around 65 degrees, is this good enough? The thorns developed in summer.

I have no experience with Hylocereus but my first thougt was that the combo 65 degrees ( which would be close to 18,5 celsius) and no light isn’t ideal.. I wouldn’t expect any plant to go dormant at such a temperature but I could be wrong.

It all started in the summer... also I overwinter every year like this

Bright sun tends to make spines grow longer (they act as a sunshade for the plant). But maybe you're asking why your plant's spines are needle like whereas the spines on other Hylocereus can look smaller and more thorn like. I think the needle like habit is a juvenile trait that disappears when the plant matures

These are seedlings, right? I also think adult plants will change their spines to shorter ones.

My plants also do not grow at similar temps (15 - 21°C night/day) during wintering.
