Hey guys.
I am going to buy a 350 real wattage LED.
I have 3 cfls 2700k for flower, 2x20w & 1x32w
= 422 watts
I know i should go for about 30-50 watts pr sqft
I am from Denmark, so i use m2 instead. Would it be a waste to go over 50watts pr sqft?

If i buy a 80cm*80cm*160cm, it would sound like this:
0,80cm * 0,80cm = 0,64 m2
0,64m2 is about 6,9 sqft
So my lowest watts should be:
6,9 * 30 = 207watts
And my highest watts would be:
6,9 * 50 = 345watts

Would it be a complete waste to have more watts in here? Please give me some advice :D
And how many plants do your recommend in this size tent? I would go for 4 to fill out the space

It will be cramped inside, go bigger. Also what do you mean by real led? Are you going for the crees such as 3590s? I haven't been on for months, so I don't know if the leds have been updated.

60cm w x 1.6 x 1.6 h was my last run. I pulled about 1p, from a 400w cxb.
Can't remember how many plants I had inside.

If I ever go again, I will add my extra 200w cxa3590 inside as side lighting for the bottom section.

By "real lead" i meant true wattage. So it is a 1200w led but 350 actual watts.. Sorry

And oups... I meant 80x80cm and not 0,80cm haha
I was high at the moment

Would you go bigger than this?

ok so 80cm = 31.5in
so its a 31.5 x 31.5 x 63
nearly a 3x3

that said if your looking to grow just for you it should be good. you could do some plant training on 4 plants and do a scrog or one plant with lots of training.
the led alone would be good for that space I wouldn't bother with the cfl's.

Don't bother with CFL, electricity prices in Denmark are enormous so you really shouldn't.

What LED growlight are you using?
If it's some Amazon/Ebay discount blurple LED, the wattage is fine. But it's a bit inefficient.

Best philips LED bulb are actually a bit more efficient than cheap ebay blurples. (and cheaper)
Just remove the bulb part so they're directional.


Just get some ceiling sockets and screw those in a piece of wood for a makeshift panel.
