Hi, @michaelyeo91 ,im not sure specifically why someone would say that,i can think of at least one scenario where the yield would be increased..HID lighting results in lots of heat.with the cool tubes pulling/pushing the heat away from the tops of the plants,they would grow/yield better. Reflectors may play a part but an important detail to not overlook is a quality bulb,some "cheap/cost efficient" bulbs have a narrow band of light,while the more expensive bulbs have a better/fuller spectrum of light...hope that helps some...peacegreen crack would be one i want to grow at some points
lsd looks good but in UK (every purple pheno weed)
taste lke crap so. unsure weather i want to do one.
yes i have look in there
but they dont mention some of the other
seed banks like cali connection etc really
purple cack look really good from there
also before setting all my light up
i brought a cool tube
some people arre saying the cool tube will affect my yeild is this correct?
if so is this due to refelectors or glass?
could extend the reflectors my self need be.
or are people taking rubbish?
thanks
