Hi all, just that really. Is it ok or not to use water from a water butt in a greenhouse. It has a lid & collects from the greenhouse.

It's my Mum's & she has said that the water shouldn't be used in the greenhouse. (She's always right !)

There is no knowing what spores and bugs have been collected with the rainwater, and I wouldn't water young seedlings with it because they can be vulnerable to damping off disease even using tap water.

I would think that most people do use their collected water in the greenhouse though, including me, but I do try and keep it off the leaves just in case (a good practice anyway, especially with tomatoes.)

I use it for everything, apart from seedtrays and seedlings

Same here.  I don't water seed trays or seedings with it, just in case I introduce damping off disease.  Bigger plants are fine with rain water but if your mum says no, I would stop using it just to keep the peace

I use collected rain water for my greenhouse plants all the time without any problem.  Just be careful of the difference in temperature, I fill up a watering can and keep it in the greenhouse about 24hrs before I use it.
