moved to the grow room in 2 litre pots,2 units of 250w mh each for 18 hours on + mars 192 reflector that works at this stage only 6 of the 18 hours.
have 2 temperature monitors and one of them (ebay item #332472350186 works great) controls thermostatically a 400w oil radiator which engages at or below 19 celcious to keep cold out at lights off. (night outside temp can be 7-11 degrees)the 18 hours on are done during night to keep warm room and 6 hours off during day,that method has proven itself in the past for me with best results.
a few small vents in the room to keep airflow + larger intake vent
Installed YI Home Camera wifi connected that gives me a quick look from anywhere i'm at.
@softsecrets,here's what i (was) am doing:
i started flowering full power with 500w (2 X250w) HPS and mars 400w led reflector all together..
as spring has threatened to lift the night temps (which is when i am lights on) i needed to let go one light which was hps or led...decided to let go led this time and since week 4 flowering i went on with 500w hps only...that kept my room stable at 25-27c during light on.
i think i mentioned it earlier in one of my diaries - ROOM TEMP IS WAY MORE IMPORTANT THAN LIGHT INTENSITY
