i thought the colour spectrem of led light was wrong for growing plants, compared to metal halide and mercury lights? could make a cheap indoor all
year green house tho if its true
There's alot of controversy over it, and finding that right spectrum for the specific plants i think is the key. Different plant's need different
light im pretty sure but don't quote me on that. I've noticed since they discovered led's can grow plant's, several companies claim different
light spectrum's saying it's better than other's. Some add orange and yellow's while some say just red's and blue's....I use them with just the
red's and blue's with a 3:1 ratio since blue is brighter. At the end it come's out as a purple light which will cover all growth cycle's, from
seedling, vegitation and flowering. works awesome with tomatoes!
Some die hard's will use the specific spectrum for the specific cycle's I havn't done it myself but they claim you get more growth doing it that
way, it's still fairly new to me and still working on finding right spectrum.
And yes is very cheap lighting for all season imo...just hard if you have different plant's with the daylight and nighttime, or manipulating them to
think the season is almost over to start flowering but you can manipulate any plant for that as long as they are mature enough...
Alot of illegal growers switch to them cause they are less detecable, with less heat! That's actually were i researched led's from was at those
forums, made me very nervious just being there but those guys really know's what their doing!
