Tetrahydrocannabinol is a lipid assumed to assist in defence against insects UV and stress. Ash composition is a combination of the oxides potassium magnesium heavy metals carbon which is affected by temperature of combustion. Finishing can use 10k UV A UV B to stress and induce...

So too many nutes and sweet Mary Jane becomes Mr Hanky and we flush it all away down Arizona Bay

Do you recommend R O water? Does that help use up nutrients? Can that cause cal mag lock or does that not matter at this stage?

Well I just bought a 600w nanolux digital ballast with a HPS and MH generic type bulbs and a small reflector no glass. Will get a 10k finishing bulb soon and check out those bulbs you mentioned. HPS photon flux density is far higher the HID is more than spectrum. LED targets spectrum cri...

ATM I use Osram Oslon SSL 80 @385 nm to start then add UV B later in small increments with reptile CLF on timer the main set up is CLW with side lighting and cxb 3590 3500k. Cirrus reflex UVB is a diode high cri with UV B and UV A they recommend it is used 15-30 minutes a day. CMH has the...

Yeah I agree the exact chemical composition is not known and you got to get them work nutes off push em hard make. I am using coco perlite and its very forgiving but the temptation to push to many nutes through is an error it will lock or add so many compounds to the carbon atoms it is any ones...

Atm I am growing digitally but want to add hps or cmh which has great cri. For some reason hps get the fattest flowers its not the spectrum which isn't that great from a digital pov but hps was designed to push through fog it is more than spectrum its the energy type I guess. Unfortunately...

Yeah I am going to use timers stay out of tent I use glasses and hoody its not a lot of par but any wavelength that close to uvc is bad news. I train them early with uva just one 3watt osram SSL 80 take them out side for training just to get some and UV A UV B for a couple of hours then...

White ash is oxidisation.. black ash carbons from plant matter ...the grey ash the combination of both as it burns

Ask Trump....we can only hope. Apparently there are thousands of people turning up to ER in the US from tanning beds they got burns and injuries We banned UV tanners down under here in Oz so if you see tanned crew in winter they are prob growers

Yeah I never used them I got a CLF reptisun 10 @24w on the way I read they only have a small percentage of UVB and UVA. I read 1 will suit 1kw I am running just over 2kw but only small amounts is what I am after just enough to trigger cellular mutation not fry it lol Think JD was running a...

Yes the chlorine dioxide kills pathogens and pollen the gas released from bleach would be very effective and actually kills the pollen where uvb mutates cells they become sterile not sterilized lol water impacts fertility also its not necessarily killing pathogens or spores but I got to geek out...

"quora How-do-ashes-get-their-colour" Hey I am to new to post links but there's good data at this site ^^ if you Google it. Saw this science article on ash colour. He explains the black white grey ash as caused by refraction of the base chemicals and metal salts. Black ash is refracting the...

Yeah that sounds intense that would be dangerous that much UVB it damages or mutates our cells as well as plants its a bad cancer risk. Bad for eyes its so close to UVC its scary Glad you told me that I got a globe on the way and have same reservations UVA is said to help with out risks of...

Sorry about raising the old thread just been trawling the forums this is the only one I joined. Yes water is the go they say was just wondering about UV and curious if it maybe useful? I guess most of us would be wary about to much UVB on our plants and apparently excess uvb damages pollen...

How about UV to sterilize pollen? UVC is used in UV air purification it can also be used in hand held devices on surfaces though the obvious risk of UVC is an issue. How about UVB bulbs left on 24/7? There are scientific articles on the impact on pollen with UVB and sterilization could a UVB...

Yeah they got a lot of R and D with it in Germany apparently. Osram are working with 4 universities in a big UVC UVB project.

I got no idea what alibaba is selling lol I was just reading that Osram are developing high strength mass release UVB diodes the 280-310 as well as UVC. The osram ssl80 uva I got at 385 is really strong a next gen osram uvb diode could be beast

Alibaba confuses me sometimes lol I saw some new epistar strips at 300 nm but no idea what they are like. As far as I know the Cirrus reflex uvb is the first to use uvb diodes they have a little in 290-330 and a large 380 UV A peak but they are way over priced just wish I knew what the diodes...

Reptile lamps can cover a lot of the low spectrum if you get the right one you might get some spikes in green maybe avoid yellow for the heat or the ones that have a lot of high far red they are a good option some reptiles use horticulture uvb also. I am not sure why low bandwidth diodes are exy...
