Anything I should know about these 2 strains before I order?

Sensi Seeds - Shiva Skunk

What is known about these strains from growing experience? smoking experience?

This will be my second grow, following on from Skunk #1

Also, they are feminised seeds, just like the skunk #1 seeds I bought. Through opinion is it worth paying more for feminised seeds? or is it worth growing and separating the males from the group? I have limited space, ie no space for males really, just 2 or 3 plants tops.

Any views would be appreceated thanks
