regarding legal status in germany ... its worse than before "legalization", only 2 patients have the official permit to grow (and their permit is running out, as its only legal for the duration of a year, then you have to renew it, which will not be prolonged), all others have to get their meds from the pharmacy where a gram cost from 25 to 40 euros (not kidding) - the problems are coming from the health insurances, highest priority is to ban all growing plants .. to move all patients to the pharmacy ... which isnt the worst idea - but .. but ... who is gonna pay 40 euros a gram of "bedrocan" a F2 jack herrer, that got "cleaned" with the help of gamma rays .. yummy ... anyways, the idea is that those health insurance companies take over the payment for the meds, as it is with any other meds too ... for example you have real cold, the doc prescribes antibiotics, lets say penicillin, and the bill is paid by your health insurance company ... so far so good .. when it comes to weed, they stop paying and you have to go through different levels of courts and judges and bureaucratic shit , even then its no guarantee that those costs will be lowered .. and there is absolutely no logic behind their decisions other than keeping that plant unreachable - bc they know - they have a treasure which is actually working and healing ppl ... poor doctor will become poor, as his patients get healthy ... he cant make money with them when they are healthy ...
i know of a strict situation where the health insurance company has no problem paying opiates for him (which are double the cost of weed) but wont pay weed, its a big mess in this country as nobody is really prepared for change and weed and its users are still stigmatized like 20 years ago, its a local thing for change, and im happy living in berlin, as berlin is the most relaxed city in germany when it comes to inhaling
(even the grow gurus from legal states were more than surprised how relaxed berlin is, they felt its more legal than in colorado and/or california .. said both . mr tommy chong and mr ed rosenthal, who were here in february/march at the icbc; i was smoking infront of my hostel when i moved here 2 years ago, when i finished i turned around just to become terrified, as 2 cops were standing 3 meters behind me and were watching the entrance of the hostel, impossible that they havent smelled it, impossible that they havent seen it ... im not used to such situations as i grew up, like all you other freaks
, in a time and a place where this plant was illegal and all "actions" around it where handled differently ... now imagine how this ascent is being "transported" across the whole country ... yes, it takes time, a lot of time, there a so big gaps that you can easily think you are in another country , from totally legal in berlin (tho not really legal on papers and in reality) to being handcuffed and jailed and having your apartment searched because of a zip lock baggy !!!without!!! content, which happens in munich (in the south); you can say the further up north, the more is the plant relaxed and "legalized"
as supplements PatientZero ,
take a look at sanlights M30 module :
https://www.sanlight.info/en/luminaires/sanlight-m30/
- about 130 euros , 30 watts (only - therefore supplemental) - but bc of its tiny dimensions, its no problem to integrate them into any small room/place,
or, like somebody further up mentioned the led from secret jardin , they cost about 70 euros and they are a good option for interplant lightning , and while we are here, phillips has a new range of flouroscent tubes, like the oldschool lights, in length of 60cm, 120cm, and 150cm - instead of gas, they are filled with LEDs, also bc of their design they are optimal as sidelights
and my favorite module from Hans (the guy behind the bonsai hero scissors) , favorite bc its has the best price value , a cheap build - a mini series - but with the best chips out there - unfortunately its a blurple panel :
Home
as you see, you have a few options, veg/mother or bloom or veg/bloom and a noise free version without fans from 60 watts to 180 watts (only the small 60/70W versions are passive cooled, the stronger ones need active cooling, which is also heat controlled, meaning the fan is only blowing when it reaches a predefined temperature, otherwise its noise free) , 2 of the 180W panels are supposed to replace a 600W bulb, i cant say more bc i have no direct experience, i can only tell you what my customers tell me, and there is clearly a trend visible :
about 2/3rds of all buyers are satisfied , their results are equal or better than before the switch , but 1/3rd dont get along with them, they fail, i cant say really why, i mean a little higher temps (2-4 degrees) and a touch more Ca is the only change you have to keep in mind, and if you neglect it, it shouldnt be such a big problem to "give up" a whole run- but it happens - so im advising every single customer not to switch all lights to led, take only 1 bulb and see if its working for you, bc if its not (can happen) you only "loose" 1 bulb and not the entire room
but now for something completely different !
i read the word terpens - and unfortunately no high pressure sodium light, or metal halogen or even led cant compare to the results of cdm/cmh bulbs, they give off extra uv radiation thats pumping up thc and terpen levels
i came across john berfelos youtube channel, he "showed" up somewhere in the shadows of mark - bubbleman - well this guy has not only a growroom, no sirs, he has also a lab toy , a gas - chromatograph ... so he is growing the same cut below hps, led and cmh; he is testing with his toy his results, and while hps and led are on par regarding quality and quantity - cmh is overtaking both

im not sure that this is the video im thinking of, if not its another clip from him , all in all a great channel, actually i was following his 99% resin head hash ...

the issues you were speaking of are the blurple lights, that have only red and blue colors, those can be problematic with some strains, dont forget - most of them (strains) were "acclimatized" to hps lights the last 40/50 or so years, so they thrive best below this kind of lights ... actually its the landraces from the equator that make problems, or hazes in general, that love blue lights more than orange/red lights , and some typical outdoor varieties have also some issues with those blurble lights
we are here talking about COBs (chip on board) , they are all white (in general) having full par spectrum , in different "colors" /
"shades of white" from 2700K to 6500K , but all white in general, with them there is no issue anymore with problematic varieties , they will feel like home
man man man - im such an idiot - we all know this already by now (i hope)
i was reading LED supplements - but you were typing UV supplements ...
anyways - some good news - cmh/cdm bulbs come in different watt versions, from tiny 5 watt or 10 watt bulbs, to 35, 70 and so on watt versions , all up to nearly 1000 watts
combining both worlds LED + CMH/CDM is the best thing one can do besides simulating the sun (which is impossible), meaning quality and quantity cant be better , no other light sources can give you these results
and the best for the end, ive seen a dozen or so threads where the grower got as much yield with 315 watts of cmh (1 bulb) as with 600 watts of high pressure sodium lights;
and meanwhile they are also made double ended, like their cousins hps and mh
i hope i havent made too much complications for you by extending ideas and solutions
