Does it really conserve energy? I mean, you grow them for 4 weeks at 24/0 and they are X inches tall. If you grow them with 18/6, it might take them 5 or more weeks to reach the same X inches tall. So, you use less electricity per day, but you then have to go more days to reach the same point. All in all, unless you have a reason to slow down the growth (can't handle the heat without the 6-hour cooling down period, flowering rooms/cabs won't be ready for a while, whatever), then using 18/6 seems like sort of a waste of time, literally. On the other hand, as long as you're in no hurry to get to harvest day, it doesn't really matter.
jamstigator Reviewed by jamstigator on . 1,000wHPS with flourexes? I got an Idea from an outdoor grow I did last summer where plants got only full strength light for 6 hours a day due to foliage blockage. Only from 9-3 did the plants get full strength light becasue before 9AM or after 3PM the leaves of surrounding plants obstructed the light a great deal but the plants came out fine because they got 18 hours of light with 6 hours of intense light. Can you use an 1,000w HPS and fluorexes together for dual spectrum vegging? I was thinking about maybe Rating: 5
