I nearly got a Marshydro but i went for a Vipar 300 reflector instead,both lights had decent reviews for their price,and i gather that both lights need a hand during flower.Im using a 250w red spec.HPS at the minute,but im gonna get another led unit for flower only and combine the two.Vipar for veg,and on half power for bloom.Doing away with HPS to keep electric bills down.
Are you aware of the extra cal/mag consumption by plants under leds?
heres a pic of my buds at 5 weeks of flower.
