hi there, good question...

this could depend on where you are in the world and your local climate... 

an example for uk where i am:

last risk of frost is mid-May so then is safest time to actually plant outside but you can risk a couple weeks earlier..so working backwards from that is what you should do..

How much indoor space do u have to spare for it? and what light are u planning on using - led/electric type or windowsil sunlight for example? if enough space and light you could start now... 

if you germinated now you have nearly 3 months indoor veg time and could put out a plant 4+ feet tall and very bushy easily. It would then have a couple more months veg time before flowering would start in late summer

Be sure to choose a suitable cultivar for your local climate.. something with high resistance to mould also advisable 

good luck

Thank you much appreciated I’ll start like yesterday as I’m in a very warm place like so warm my plants will need shade in the dead of summer (well they did last year) I am using a green house not much space though as I’ll hide them in there until I can move them out...

I live up near Lake Ontario in North America to get a jump on the season we use cold frames to protect the plants from frost, they are kind of like a mini greenhouse.

Cold frames are easy to set up all you need are some old windows, scrap wood, or bails of straw.

Thank you, very intuitive I’m sure the straw insulation does a very good job. I am using this make shift Polly tunnel at the moment
