I hear you. I am sure they do and I certainly do not debate it, I have been down that road. It took me a long time to source the "blue" bulbs inexpensively, but a search found the ones I like, I go to the nursery store here, I think they are actually 5500K but who's counting? ME.. I do however like the 2700K ALOT that I scored at the big box store. They were hidden in the outdoor lighting fixture area. I do like them for the cost. I bet the four I put in for additional lighting give me at least a 20 percent increase in yield. Though it is hard to say, I have made more than one change to my system since adding them..BUT the buds under them are definately happier.
It's hard to answer this question with anything but, "that's not enough light". There is no doubt in my experience that this plant will want more light regardless of the spectrum supplied. So I agree with you Hotrod.
We could go to 50 different grows and find 50 different methods. My advice to anyone taking on this hobby..and take it lightly because I am no means an expert..Is this, read, study, read, and study some more. Find the best way to adapt your grow. Follow proven basic "guide lines" the plant needs five things, growing media, light, water, food, and love. You are in charge of all of it when inside. Do your best, learn from your mistakes. If your one seed doesn't make it..get another one..or ten. Good Luck.
