good info. all
to add (again): on the reverse, a hps bulb can be used during veg. and bloom cycles to make nice patterns of growth.
however, we find that trichome content and levels of essential oils are most abundant under levels of red spectrum (indoor or outdoor) rather than blue light during the latter stages of ripening.
big buds is one thing, but buds full of resin is something else, those mh bulbs are also more expensive to replace!
(note: not saying ya buds aren't full of crystals MTF,,, just adding to thread... lol)
