Entering 5th week of flowering, everything is going as planned. Optimal variation of: - Day Temp./Hum. - 28-29'C/35% - Night Temp./Hum. - 18'C/60% (would like that it goes bit lower, till 13-14'C to activate anthocyanins. But I don't want to force it.) Watering amount is still 1L per 24h, sometimes less, but soon they will start asking more than that. Because of this 1000W input Black Dog, which have light output like 2100W HPS, flowers become significantly bigger day by day, and plants are thirstier, absorbing more fluid. Also set it up two reflecting wings that visibly lighten more bud sites, now when plants are stronger. Hope that there won't be any hotsports or burns, but I totally doubt it, considering on great ventilation that maintains this optimal temp. and provides breeze, between light source and plants suface.
