Question Best advice for adjust my light

   RSS

I’m running a MarsHydro 2000 in a 60” tent and can’t raise it anymore.  After 2 weeks of thinking my problems are pH or excess nutes, I’m now thinking it might have been light stress all along.  

Would it be better to go from a 20/4 to a 18/6 cycle or drop the output from 100% to 90/85%?

If you are dealing with light burn leave the time the same but dim the light. The intensity is usually the issue.

Hey Buddy i use Mars TSW 2000 i just got shorter hangers or get some chain and adjust it to get a bit more height. you can also remove the drivers from  the top of the light which will help with heat being so close to the roof of the tent also . Not sure what your growing if its auto's either of those light schedules are fine but best probably sticking to the schedule your running don't mix it up to much 😜

Theres an app you can download for most phones called Lux bro. Download it and check how much light the plants are getting at the canopy!

As a guideline your looking for around 

5000-7000 for seedlings

15000-50000 for vegetative growth

45000-65000 for flowering plants.

 

Good luck 🙏

Thanks @monkeydo and @schroomy for the reply! I reduced the light output to 75% and will rework my tent after this grow which should be able to lift my light up another 5"
