@jeeje, never tested and im not anykind of auto professional but i would say yes it can shorten growth time. What it cost for plant is different story. i have grow autos at 24h because of heat. Too cold otherways half of the year. 20/4 is good. 16/8 pretty pointless cause you can 12/12, grow photos and save in electricity.
@Hattiwatti, those are solid times yeah! how many hours did you keep your lights on? i hear if you do like all the way 24 (for autos only) on it cuts of like a whole week of your growth
@Xonidan, 60-70 cm , plant 2 is 65 cm from top soil towards top. added picture special for you, but its hard to get the full plant + allowing to read the centimeters. (day 32)
@LaFrenchCulture, yeahh :D might gotta add more lights thinking of getting a long light bar cuz the tent is to big for only a mars hydro fc 3000 maybe like 2 light bars or something in oppside orner like an L for some extra thickness i guess. any ideas on the matter?
