I've got a windowsill with a number of avocados growing from seed (I'm in Rural Auckland - so US Hardiness zone 9b, heading towards winter) - A couple of my plants have just started to poke out the top of the Avo (ie stems, not roots).
For now, am I better off leaving them inside my house, which would have a more constant temperature of around 18-24 degrees c, or putting it into my unheated polytunnel which will get warmer during the day, but much cooler at night. I'd imagine 8c - 35c [ eventually going down much colder - I expect temperatures are a bit marginal in winter here ] and with greater humidity and probably more overall light ?
Also, if i'm moving them to the polytunnel can I transplant them now, or am I better to wait until they are 15cm's or so tall ?
