Help for a really small setup

Hi everybody!
I have a grow room which is 35x35x65 cm or a little more then 1x1x2 foot.
I've already bought the lights but I'm not sure of what I've done.

I'm here to ask for your guide.

I have 67 cm in height, but I have about 13cm of pot and 20 cm of carbon filter which means 35 cm of actual space.
So of course I'm going to do everything I can to keep the plant as low as possible or, if there is no other way, i'll put the filter out of the grow room.
The problem is: what kind of led light can I use that I can keep as close as possible to the plant without problem?

1 foot LED strips driven softly will probably be your best option. Bridgelux EB Gen 2 or Gen 3 or some 1 ft. Samsung strips. Make sure you look at the product dimensions, and that you can physically fit them in your space. If you're comfortable putting the light together, you will need a driver (power supply), a power cord, wire, a few connectors. Also aluminum (probably flat bar to utilize every last inch of space) for the strips(with thermal paste or tape in between) for rigidity and heat dissipation is an option.

Is this the absolute largest space you can use for your garden?

Go look for Blynx's threads over on ICmag, if you want inspiration for your space. And maybe search the micro growing forums here.

I think you just find the solution for me...
Blynx's threads on ICmag has hundreds of pages an it's impossible to find everything but I've seen the test he did with the led bulb and I've seen his pictures that helped me understand how close can I keep the led to the plant.

This is my grow room actual setup:
1586707181600.png
As you can see the filter takes a lot of space, especially with the led strips panel I built. The problem with my light is that even if I have 600 leds 6000-6400K that should be around 3000 lumen the light it's kind of weak...or at least week for my seedling that it's struggling to grow as fast as I think it should. Those 600 leds are 2835 SMD and folks that I know use same kind of cheap led strips are using 5050 smd leds which, i found out only today, are about 2 times brighter then my 2835 SMD.

So yes, I've wasted my money and my time. On the good side I can always reuse all these 5 meters strips I've cut in 30cm pieces and solder them together again for other use. Fortunately they were around 12-14$ each...it's more the time I've spent then the money.

Anyway long story short, here is what I thought.
Thanks to what I've read in Blinx's threads, these led bulbs look like the best choice in my case for two reasons.
1- I can still keep them really close to the plant. In Bllynx's photos I can see him keep the light between 15 and 5 cm away from his plant without any problem. In some photos the buds are almost touching the bulbs.
2- If you look at my grow room you can see that the light panel, which i thought was the best idea in my case, can't go higher because of the carbon filter. But if I use Led bulbs I can put 2 on the left and two on the right of the filter, slightly tilted toward the central area where the plant will grow. I think that because I'm not looking for a ginormous yield, but just a fair one, I can go with about 4x 10w led bulbs for growth and for flowering...I can maybe add 2 more 10w bulbs in flowering but maybe in the next try.
This way I could keep the filter inside the grow room, so that it works as it should, and gain some useful cm of space.

What do you think?

Nice job Boatguy!
Yes, i think scrog would be the best solution in my case...Or some SLST aka "Stressfull Low Stress Training" :lol:

You had the right idea, just not the best strips. 6000k is too high, most are using 3000k-3500k for veg and flower. What do you have for a driver/power supply?

As others suggested, I'd go with 1 foot Bridgelux Vesta strips or the EB's to save some money. They could go on top, on the sides, or both.
@Rocket Soul has had excellent results with 2700K, 90 CRI Vesta's.

Help me choose a 4x4flowertent light

As for 30% higher efficiency, i believe i said at 660w over a 4x4 but could be mistaken . You said: "The Bar-8 has a 1730 ppf dude. 2.8 UMOL/J set to 660w. 2.7 (2.689) @ 900w." OK, how is 2.8 30% higher than 2.6? And how much higher would the efficacy of the HLG be if dimmed the...

Thank you for the suggestion.
As I've read that COB led need to be kept at a certain distance from the plant and this is exactly what I can't do.

I've read that a distance from 12" to 28" it's the sweet spot for COB. I have around 14" of space from the light to the pot. There is no way I can use COB. Not even if I put the filter outside the grow room.

Because the strip you linked are COBs.
Today i found 6x 11W led bulbs that I can use and with only 13 LED they have an increadibly strong light. They are not COBs led and they are not stripe but, because I already have them, I will give them a try. At lest I know that this led bulbs can do their job about 10" from the plant but also as 1" without causing problems.

I don't know. I'm not an expert but I can read a description and the description of the led strip you linked is:
