NEW guy building grow space

Hello fellow ganja lovers,

Let me start by saying this is my first post. I am a long time reader of RIP and love what most of you guys do Hate the assholes though and am sure I will have my run ins.
Never have I done the forum thing before. So please guide me along this journey.

I have only grown in my outdoors and have recently moved to the city.
I suffer from a rare form of epilepsy and have been trying to manage it with out the $1900 medicines that give me worse side affects. That is what has got me into growing. With that said I now live in a condo in the middle of the city and do not know what I will be doing for my meds as I am not comfortable consuming what others have grown and will run out in about 6 months. Plenty of time to start a new crop.

I have determined that there is a great amount of resources and knowledge at our fingertips here and I should use them. If some of these idiots can do it I'm sure I can.

My space to start will be small as there is no need for me too spend 5k and make mistakes which I will. I have read a lot on the 2x4 space and think that will be perfect.

My question is about lighting!?

I want something easy to cool-very high intensity-and low power consumption.

From what I have gathered they way to go would be the new COB technology. I have watched all the YouTube videos from growmau5 and read the articles by SupraSPL and all I can say is thanks guys. Your work is appreciated

My plan is purchase from these components from Kingbrite

1 HLG-240-1400ma
5 CXB 3590 3500k 36vI
5 Glass lens
5 COB holders and connectors

As I am not experienced in the indoor grow space will this work for my application?

Thanks again guys.
SMOOTHseven out.

the 3500k in the cob name refers to its kelvin number. 3500k is going to give you very leggy vegetation, it has less of the blue spectrum a 5600- 6500k light will have, which causes short internodal length, and bushy growth. those would be excellent for flowering, not so great for veg. you could get a supplementary 6500 light to go with it maybe, or add a couple of strong blue leds that you could switch on during veg and off during flowering maybe?

so id be better off with:
2 3500k
3 5600k
to give a better spectrum

i don't know your budget, i would just build two lights if it was me. you can veg under a 35 and flower under a 6500, both have more to do with photoperiod than kelvin temp. but ones better for one, and ones better for the other. i'd go 3 and 3, and turn off a 35 during veg, turn it back on and turn off a 65 for flowering? may just be talking out my ass, never actually tried that, but that is what i would try first.

what would I need to fill a 4x4 space growing 80 day autos? The price is the price I need to do it right the first time the budget has no room for error.

i've never built an led grow light, but i have been thinking about it and looking at them a lot. most of the ones that say they are good for both have a switch, when you have it one way some of the leds that put out red are off, and some that put out blue are on. when you flip the switch, the red ones come on and some of the blue ones go off. some of them also have IR leds, which sounds good, but IR is only actually needed for about 20 minutes a night, right at the beginning of your dark period. this is part of the Emerson effect, which you can look up for yourself, i'm still trying to figure out the best times for Ir myself. if you use it properly its supposed to significantly shorten your flowering time, by as much as ten days.....but back to your original question, i'd say look at all the top end units and see how they do it, but all the ones i've looked at use the above set up, some on for one phase, others on for the other phase
