first timer outdoors

So I normally do my work under 2x600 and a 400 I wanna go outside yeah I know its kinda late but I'm looking to do some 3 generation sour60xpurple gems that I've been breeding I got them finish at 75 days so I'm working can I drop them now or would it be a waste of time I already have a perfect location also I'm in the north east all help appreciated.

So with a bit of research right now getting 15 hrs of sun light from dawn to dusk think ima go for it

You will be good they won't be monster but nice height
