I have a 135 UV and a 150 HPS. I heard UV isn't good for flowering. My question is I was reading that you can get more females from seeds with more blue so is the UV better for germination and the veg cycle. I know 150 HPS isn't very strong but it does generate a lot of heat and I heard you get more males with heat??? but I also know seeds like heat so whats a good temp for your seed to sprout but not be predisposed to be a male?

You're opening a controversial bucket of worms with the "What makes more females?" question.

No.


YOU don't know.


Because you're totally clueless.



A good temperature range for sprouting seeds is 21-28c.

This is well within the plants expected limits and should have no adverse affects on the seeds at all.

Is the UV light better for seedlings and the Veg cycle than the HPS?

No the UVB isn't good for seedlings, they haven't hardened off yet, and won't take all that UVB specially 135w. I use 120w UVB in the flower to increase trichrome production, but that's all I've ever heard it being used for.

I have never used a UV before.

Isn't it less than 400nm wavelength?

It's strictly supplemental light, running along with my 2200watts of HPS.

its in the DNA of the plant if the seed will be female and or male i truly dont believe that giving a plant a certain spectrum of light will give it more chance of being male or female its down to he luck of the draw
