NOOB question for NonNoobs about harvesting seeds

Wuttup y'all. Im not sure if im posting this nI the right place. I didnt see a dumb noob question secction. Lol

If I'm trying to make some seeds, do the conditions & environment effect the quality of the seeds I harvest?

For instance, say I harvested seeds from some plants grown under t5's in less than optimal conditions and also harvested seeds from plants grown under hps in great conditions.

Would all those seeds be able to produce great plants as long as the genetics were good? Or would the t5 seeds produce shittt plants?

they will be fine, as long as the plants reach maturity ok under the t5 immature grey seeds are not good
if you do it right many folk grow fine with t5

imo too, any light that can finish/mature the plants properly will do. I'm using some LED's that I use for veg, they suck at flowering from a yield/density perspective but I've done a few runs now for seeds and they turn out fine. Like skunk said, maturity is the key.

Thanks for the replies!
