seems you dont have to go far to find discrediting info

Some initial success in purifying phytochrome from etiolated oats (Avena sativa) was reported in 1964 (Siegelman and Firer 1964), and many workers subsequently used dark-grown oat seedlings for phytochrome extractions. As a result, much of the biochemical information on phytochrome is derived from studies on oat seedlings, although there is a considerable amount of data on phytochrome isolated from dark-grown rye (Secale spp.) and pea (Pisum sativum) seedlings as well.
so chemically altered mustard seed in a petri dish and dark light oats need far red light. and people bitch at us for claiming they grow tomatoes...lol. I'm not saying we couldn't use more lights but as far as "you invest in a cost of 1 leg for LEDs and
you find out it's not really even enough". it seems as if it's "enough" for veg anyway.
