Northen Lights is my preference, better smoke to me. Heres some info
Northen Light - Northern Lights is highly adapted to indoor growing. Nearly all promising modern indoor strains contain NL genes. High flower to leaf ratio, compact buds, good yields and exceptional resin production are all characteristics displayed by this wonderful plant. Northern Lights is a most lucrative plant for the indoor grower. The smoke is full bodied yet somewhat neutral in flavour.
But since u were looking at NL and Haze, why dony you look into buying
Northen Light x Haze
Some Info is here:
Northern Lights is crossed with our Haze to produce a heavier set plant. NL/Hz still reaches tall heights yet dense Northern Lights style form on the long stems. The inner bud leaves are a bright lime green. The smoke has that sweet-sour taste and produces a stony yet up high. This plant needs careful trimming indoor and patience, but the reward is worth the wait!
Not sure on the cloning part though
