I Have my AC Infinity 642 grow tent and Viparspectra XS2000 set up and working a couple of days ago - I have turned up my grow light to 60% of power and lowered it to 24" above my leggy seedlings as recommended in this incredible site - New question to use the cheapest electricity (I have time of use pricing) can i run my grow light on for 8 hrs, then off for 4 hrs during peak pricing, then on for another 2 - 8 hours as needed - will that on - off - on schedule screw up the plants internals
