Grams per watt
OutForRealanswered grow question 6y ago
You could be surprised by the final yield even if it could be less than what you are expecting.
I also feel like gpw is not referring to gram per watts per plants , it is a calculation for your grow area depending on the light power but your space could have been used by 2 plants that could perform a twice higher Gram per watts

have a look through the diaries there are not many that achieve 1gpw
Aim for 1 gram per watt for sure whether you get there or not
Good luck

What % to keep lights at during late vegMy question was around what power % I should have my lights at? My light is 300watts so I am assuming 50% = 150watts?
Is this enough to continue vegging my plant? I have noticed the growth isn't as vigorous.

Light spectrum during veg and bloom periodsI have 2 1000w full spectrum lights. Each light has 2 switches-a veg button and a bloom button. This gives 3 settings for the lights-veg only, bloom only and both lights on at the same time. What settings should I use during Veg and during flower and how close should I hang them?Setup. Lighting

Change lights off time?I'm having trouble with temperature control. My nights get too cold. My current lights off time is 12am-6am. Is it possible to change it? I really want my lights off to be from 9am-3pm. I think that would help me a lot. How do I change it? Let my lights run for 27 hours?Setup. Lighting
