I know your not supposed to water at night but the way i see it is it rains at night and day in nature.
This is a golden outlook and ALL growers EVERYWHERE would do well to take it as golden advice.
So many non-sensical suggestions have been made which fly in the face of what we know from nature. It doesn't make sense.
If you have no air movement, no dehumidifying capacity (as nature does), and all of those things--sure you probably don't want to foliar at night.
If you're doing your best to replicate nature then it stands to reason that it doesn't make much of a difference. As a matter of fact in many places (California and
the emerald triangle being one such place) it actually rains
more at night on average than it does during the day.
I mean I hate to be a hippy about it, considering I am a scientist, but if it's good for nature it's good for me.
I think probably the most detrimental thing to new growers is that they get bombarded with all of this information which is
so specific when the reality is there's been almost no botanical study of this plant--not in a sense which will deliver high correlations.
It's mostly guesswork, and while experience can help a lot of people--it helps them in many cases
conditionally based on how close their environment is to the person's who is giving the advice. This is why scientific inquiry is so important, because it controls all of these variables and gives
proper conditional advice based on a VARIETY of conditions--and accounts for the changes expected between them.
Most information like this kind of thing (don't foliar at light off) did not come from such study.
The most
honest answer you can give on something like this is who the hell knows. When I find that to be the case I go with common sense--and as jeffadies points out, it's common sense that it rains at night.
