Which led? leds are not even close to the same. 200 watts can be dramatically different from one light to the next.

anywhere from 12" in flower (depending on your diodes) to 24" in flower... (depending on the diodes).. A safe veg height could be anywhere from 20"-36" .. Need to know the brand and model name of the led if you want advice about it.

MARS HYDRO TS600 LIGHT STILL ON WHEN TIMER SWITCHES OFFit is a known problem i found 2 forum posts discussing it.
Different timers have been tried but it always remains the same.
Someone said with a mechanical timer the problem is solved I will try that as soon as I have one.
In any case, this is absolutely unacceptable.Setup. Lighting

Danger of HumidifierGood morning everyone.
So I've recently set up my new TS1000 and I'm wondering is humidifier dangerous for LED lights? It's directly under the light 60cm. And how can I regulate the temp in the room without new equipment? It's too high at the moment.Setup. Lighting
