yes im about 5weeks from seed, just repoted them 2 days ago still in recovery , tyMH is best for veg, I'm guessing that's what you meant by growth stage.
Is there any particular reason why? My light height is mostly an arbitrary number (I looked at a chart one time and for some reason 12 inches stuck with me), just wondering if there something I could be doing better...Like astronaut say mh is better for veg, but IMO i prefer to do 18 inches away from tops.

Yea I've heard that too, that's why it's important to keep them clean so you can negate that problem a little bit (or so I've heard, seems logical enough).FYI i read this today , you may already know about it , ( Cool-tubes are a great product which, for very small grow rooms or rooms running lots of lights, can be the only option for running high-intensity discharge (HID) lighting. However, they do have their downsides. Compared to an 'open' reflector, the curved glass in a cool-tube reduces the amount of available light that reaches the plant. Also, glass will block out the UV light that reaches the plant and it is UV that causes Cannabis to create and release her lovely essential oils. )
Not, not really is just personal preference, i just i fell like thats the optimal light distance, at least for me, but since u have cool tube that might b better for u, i run ma 600wt without cool tube that's why i keep it at 18 inch. toke on =====~~Is there any particular reason why?
