yeah set it to 250w and you'll be fine.I used to use 400w in a 90x90x180 tent with cooltube,that was good too. but either way you'll need a cooltube reflector. without cooltube, temps hit 33-34C easily.

Theirs a digital dimmer which can be turned down to 250 watt would that be ok is just comes as a full set

I would say it is way too big. A 200 or 250 watt would be more appropriate in my opinion.

Light: much Power less hoursHi everyone,
I'd want to decrease the hours of light to give the plants the impression that winter is coming, but I'd want to add a led to increase the power of the light. Can I apply both this ideas?
Thank for your attentionWeek 6

Wondering if doing another defoliatation would direct more focus to the main sites?
Also I have three other plants that are about 2.5 weeks younger, so I have to keep an 18/6 light schedule. Would I have to switch the flowering plant to 12/12 even though it's an auto?Week 7

Grow LightsIs it okay to use an LED Light 1000 watt (4x4x80" tent) & a UV Light 1000 Watt in a 4x4x80" grow tent for 3 plants. I want more light, I have plants growing slowly so I'm hoping to adjust the amount of light I have would speed up their growth. LED is white spectrum & UV blue-vegLeaves. Tips - Burnt

Is it worth adding a LED 18w 2700k strip light for last few weeks of flower?Should I add this light for the last few weeks of flower? I have a Streetlight 18w LED strip see pics. I was thinking that if I added this strip designed for flower to my tent like a side light it may help my Viparspectra V300 in fattening those buds a little. Thoughts?Week 12
