*UCKING LIGHT BULBS....*AMN finally a new use for something old,Thanks and a high five for the links and info.so how useful do you think these would be for the last 3-5 weeks of flowering?I flower under 3-400w HPS until the last 3-5 weeks and then they enter the 400w MH section of my flowering room. 15 years ago i started paying attention to the trics and saw that most were still clear at harvest time under 100% HPS . adding the MH has allowed me to achieve the 50/50 clear/cloudy ratio i like but i would like to shorten the final ripening time.also I notice the bulb you link to is a "enhanced spectrum" bulb doesn't this mean it has added blue?i can,t seem to find a source for wavelength charts for this or any halogen bulbs.
