I like to, (and do) test, under all light regimes with clones. This gives me a better idea of the actual genetic pontential of a female.
Testing includes:
1. Natural light (outdoor sun)
2. Flurosent/LED
3. HIDs - MH and HPS
For example, The Vito clone, it performed much better under Fluros, then it did under MH and HPS. Which is natural to some extent. But the variation was high on both ends.
So, under MH and HPS, the vito clone was a low resin producer, and average at best weed imo. However, it was superior to the Thunderstruck clone, in all aspects under fluroscent light flowering.
