I replaced my Viparspectra 450w nine days ago with a Mars-Hydro TSW 2000. I've been slowly lowering it from about 30" to 18" from the canopy. Full on. I just finished my daily routine and spotted some light stress on my Northern Lights Auto so I raised the light about 4". I'll watch closely the next few days of course. I've seen more of this light showing up on the forum in recent weeks so I'm wondering how others have transitioned from one light to another?
