Seriously. LED?
No friend you cannot grow quality medicine with LED's Not yet anyway.
people will say 1000 watt of led is the same as 1000 watt hps or MH they are just ignorant. besides you will spend about 5 times as much in lamps to produce the same watts of Led light.

Never forget .When someone is obviously trying to sell you something their opinion is no longer an unbiased source.
