I've been doing some reading on this uv business and the effects are proven, in my opinion anyway.
However I have been really reading the literature on this and have found that if going florescent route the lamps are sunbed lamps ! No difference if looking at numbers ! Various companies round the globe sell them and they mainly use the longer time tubes. There are tubes you lie under for 5/7 min "fast tubes" and then 10/15 mins tubes and then relaxing tubes which are about 25/35 mins of cooking oneself . The ones most companies re-brand are the longer relaxing tubes !
Look fellas don't believe me if you do not wish to but like many people about on here and other similar places like to research things to a silly level and I am one of those ! The patents these companies use are not theirs for agriculture but for sunbed tubes from what I have seen ! The tubes all come in same sizes and numbers too !
If using floros, planning to, then look about at information as money can be saved ! Just like everything, it's for cannabis growing the price goes up ! Look what we pay for kelp, seaweed etc in cool looking bottles ! I was interested in this U.V lark and when I realised the lamps and running kit were sunbed ones I realised the big thing blocking my control gear in grow space was a 800w sunbed running 6 foot 100w tubes x8 obviously ! Fancy bloody that ?!?! The same lamps, relaxing lamps, it was a hire with new lamps and the company only picked up one, they had an offer of 2 for 1 and we had the free one ! Turned out free permanent LOL anyway it has a ballast for each tube so my Mrs will lose one or two, she only a little thing anyway !
