This is my setup.

2x mars II 900w, i have measured and there is room in the middle for either a 1200 or another 900w. Wondering if anyone has any experience to share about the flowering spectrum versions. I basically start the grow under 1 light, when they get big enough the second light goes on Pretty sure i want to add another light that will come on as they go into flower mode, (right now) Just wonder if its worth an extra $100 and an extra week or so wait to go with a specifically flowering spectrum light.
