So lets play around with some numbers a bit nothing will be on target or actual numbers to use for anything other than comparison.
Lets say you have a HPS that gives you 50000 lumens and only 20% of that is emitted as blue light. That still beats the crap out of a CFL with 80% blue light that would give you 15-20K lumens because the plants don't ONLY use blue light while in veg.
The HPS in itself will not make your plants stretch. Low lumens will though.
These plants were vegged with a flower spectrum HPS by the way.
I have a veg specific CFL but it didn't stand a chance in hell against the HPS.
I would say that generally it's all about the lumens if you experience stretching that is not coded in the genetics of the plant. That if the color of the light is in the neighbourhood of what it should be ofc.
Imho her flouro tube will be outmatched many many MANY times by her 250W HPS even if it is a pure flower spectrum and save her 1-2 weeks on veg to lets say 15 inches well developed plants.
PuffzterPuffzter Reviewed by Puffzter on . White Widow cabinet grow Well, I figure it's time I start a log. I bought Feminised White Widow seeds and put 4 seeds into "Root Riot" organic starter cubes. When the first baby popped up I proudly started this thread. Out of those 4 seeds I got 5 babies. (Photos in the linked thread) I had to separate them and they seem to be fine but the 5th one is a bit of a runt. We'll see what happens. This is the cabinet: Rating: 5
