1. Look up exoterra 10.0 26wHello friends,
i built my grow place, size 120X70, height 180.
Air:
Out: fan TD-SILENT 350MKS + charcoal filter
In: 5' ventilator 150MKS
Light:
6 X Cree cxb3590 3500K 80cri
Few questions please:
1. i want to complete my spectrum, can i use this lamp?
http://www.lighting.philips.com/mai...-puva/uva-1-pl-s-pl-l/927903400907_EU/product
2. do i need an infrared light?
3. if 1 or 2, how much time from the 18h or 12h i need to light up the uv/ir, and how much pcs i need to my growbox?
4. I assume that i have some mistakes or need some improvement in my designing (of course in my english), so I would very much like to learn.
Thank you!
Theres a shit load of research on uv ... Theres probably 2 shit loads of research.IMO your fine with just the Cree lights, IR will just heat stuff up and there isn't much evidence yet that UV is needed either. UV encourages more trichs but at the same time it degrades THC so its a double edge sword. In outdoor grows potency is usually a little lower for a given strain and pheno but the terp profiles can be somewhat different. UV probably lowers the cannabinoid potency overall slightly. Some people add fairly low levels of UV (much less than the outdoor environment) and claim it helps but I think the jury is still out. Just go with what your using the COB lights will do very well for you.
Light is only one thing in the environmental controls though. Environmental control is everything to yield except for genetics. However, without good controls the genetics might never express themselves fully.
Your English is just fine.

1. Look up exoterra 10.0 26w
2. You probably got enough
3. I use them after stretch period in flower.(whole on cycle)
4. Good luck bud.
I have done quite a bit of reading especially here on the forum but I see two camps, respected growers on both sides some say it works and the other say not so much. That is why I am unsure and seeking evidence and experience.Theres a shit load of research on uv ... Theres probably 2 shit loads of research.
You just have to do your RESEARCH
All these newfangled lights everyone is buying.... They are adding uv or trying to broaden the spectrum to include uv while still hitting photosystem 1 and 2
Uv proabably reduces potency....what in the ever loving fuck are we talking about?
Ask the respected growers(the ones that didnt see a dif) how they used it and what they used for uv. Then dont do it that wayI have done quite a bit of reading especially here on the forum but I see two camps, respected growers on both sides some say it works and the other say not so much. That is why I am unsure and seeking evidence and experience.

Do you go out in the sun? Its worse for you than light bulbs. I turn them off when in the grow area or wear long sleeve and glasses and a mask. Plants love uv.. People die from it... Its kinda like giving a dog a chocolate bar...it was was ok for the human but now the dog is dead.Thanks bro!
i search about exoterra 10.0 26w and i understand ist from 290nm, it is not dangerous for me? my box stand in my sleep room and if its ok, how much pices i need for my space?
