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...
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...
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...
