heres a pic of my veg /clone area. the t5s are ok here is 100w of T5 HO over clones works great, also the light has a 150 hps which i dont use much unless i want to stretch something. and the mh over the mother is 100w also .t5s side by side the mh of the same power at closest possible point for both lamps the mh doubles vert growth and gives me node spacing of not more than 1/4 in which is great for denser buds but my mh likes to kill my clones. so in my experiments watt for watt the mh gives better vegg growth
