Looking at a new light for later on into my grow

my mate did a side by side grow dutch passion power plant, two clones from same mother rooted under 2' tubes in root riots, bio bizz soil and nutes one placed under 250w hps the other under a 125w blue spectrum envirolite for veg, they were both in the same cupboard but seperated by a sheet of drywall to stop each one getting the others light, after three weeks of veg they were both at the same height with the envirolite clone definately greener and healthier looking, then swap the blue enviro for a red enviro and on with flower after 10weeks of 12/12 the hps was taller by only 2" and only yielded 4grams more than the enviro grown clone for half the power. I use 2 125w enviros for veg and have never looked back, stil use a 600w hps for flower tho, dunno how much they are in the u.s but in the uk they are GBP19.99 for 125w blue and red envirolites and 250w models are available
