4x8 lighting question

I have a 4x8 tent with a 1000 watt hps, im starting to realize i need another light but am wondering what size led i can put next to it as I don’t want to get another hid because of the heat. any suggestions appreciated

What’s your budget?

Was hoping 500 or under

You'll need at least 500 watts of good diodes. Unless you DIY the fixture, using a Chinese QB clone is about the only thing that'll fit your budget.

I could recommend lights all day, but ultimately the decision will be up to you. If it were me, I would ditch the HPS altogether if heat is this much of an issue and go all LED.

Unfortunately, there's not much for under $500 that will hold up to a 1000w.
Are air cooled hoods not an option for the heat?
I run 2.6kW hps in my 4x8 and just hit the 1 gram per watt mark after only 10 months of growing.
Couldn't pay me to move to LED.

You must use 42.3w Sq/Ft of the very best LED Diodes to equal a 1000w HID.

Gavita 1700e 645w is a direct replacement for a 1000w Hortilux HPS in a 4 x 4 area. No way around it, though it blows the budget out of the water.

Best budget LED are HLG, and will still be more than a $500 budget. They use Samsung/Osram Diodes. Dont use any other Diode if you want as good as results as HID. But you must use 42.3w Sq/ft regardless. 1000w HID/Hortilux is 1600umol, and 62.5w Sq/Ft.

Gavita 1700e is 645w, and 1700umol

Gonna take about $800usd-$1000usd for the HLG.

Do a DIY BLux eb gen2 strip build, cheapest thing I've done that seems to work.

Is your 1000w hps cooled ?

Nope, no need for it because we have such a large area, are in a basemaent, which is very cool, and really good ventilation. We also use a Dual Ended 1150w Gavita. We use all 3. 1000w Hortilux HPS

In many cases though you would need to cool them. I think it Takes about 8000btu to cool each 1000w Hortilux

Sell the 1000watt on craigslist and get 2 600 watt hps w/ air cooled hoods. LEDs get pretty hot too.

They do.. but not compared to hps... 2x 600 is a great option... or 3 cmh

Get 3 mars hydro 600 led boards. They replace a 300hps .

Should be little over $300

I think mars recommends 4 of them per 4x4

Well you only need 2 for a 4x4

It’s like having a 600hps

No, that light draws 100W according to their website, so even 4 of them would be about 80W shy of what most people would want to run for a 4x4. OP would need 10 of them for 4x8.

I'd recommend 2 @ 630 watt CMH for a 4x8.
Cost about $1200 and would add no more heat than your 1000 watt HPS and an addition Led

Couldn't pay me to move to HPS lol! I started out at more than 1g/w, not gonna go backwards lol. To each their own, as long as you get fat sticky flowers that smell and taste good who cares right?

Gavita = the KIND of todays market
