Lights

Hey just wondering if it's a conventional method used by people to use hps as a heating source in the tent alongside the resident leds.
Currently using 2000 w bestva leds which give off barely any heat whatsoever.

How big is your space those 2 lights together will cover a 4x4 at best

Edit: wait how many do you have? I assumed you had 2 for some reason haha

I've got plenty of led, it's just they aren't hot. So I'm wondering if it's better to kill two birds with one stone and get some GPS in there as a heat source aswell ,rather than about 5 high powered led and heaters.
I'm just unsure about using the led and hps in conjunction with each other that's all bro
1 watt = 3.412 btu's

You can indeed use lights to heat an area.
Thankyou my man. Have you heard of bestva led? Have you an opinion on said brand?

If you have plenty of light you should have plenty of heat those lights are the same effeciency as hps so you need the same amount of watts as you would have with hps let's say 4x8 you need 5 of these led that would be 2000w of real power draw. If you don't have enough heat in that case you must live somewhere crazy cold insulating the room would be better than just trying to add heat.

Its not conventional no, its something that can be done though.
But what is the temperature that's so cold? Is your extraction too powerful?
How many of these lights do you have in what size space?

Well atm the temps aren't fatal so to speak. But winter in England can be pretty brutal so I'm just preparing for it.
Ive insulated the tent and I was thinking rather than use a heater full time I may aswell use the heat from hps and the by product is also light. I know Ill have to use the heater anyway though during the dark periods.
I'm in a 2.4 x 12 tent.
As for lights I have 3 x 2000 w bestva.
2 x 600 w viperspectra
2 x 2000w dominators.
But I'm expecting the temperature to drop well below zero in the next few weeks.

It depends on where the grow is, as in in your house it should be reasonable temps, in a garage is a different story.
The topic came up a week or two ago in which someone was going to use space heaters to heat a fairly small grow, as you know space heaters are very power hungry and not very safe in enclosed spaces. HPS was a better option no doubt.
I like the idea of using HPS to warm the area, you get the bonus of extras light and some spectrum that you wont be getting from the LEDs. Obviously if growing with autos its even more of a bonus because you can just keep lights on 24/7. Sounds like your using photo periods so the oil filled radiator on a thermostat will be needed at lights out.
No point paying for a heater at lights on if you can get bonus photons though ey!
I would suggest laying down rigid insulation under your tent if your growing anywhere but your house, concrete floors really don't do the rootzone any favours even in summer.

Anyhow it sounds like you have lots of light, if you add HPS it might be worth raising everything a few more inches to get a bit more blend and no light burn.

The bestva 2000w led is around the same efficiency as about 360 watts of hps lighting. At a hanging height of 24 inchs the coverage area for that fixture, for flower would be closer to a 1.0 m x 0.8m space.

For the Viparspectra 600w, it's akin to a 250w hps, core footprint at 24" is about 0.6 m x 0.65 m.

You can push that coverage a little more, but that's your optimal footprint I believe looking over the specs.

Pretty much for all the lighting you have, you'll want to run about 450 watts per square meter.

@coreywebster double check me, metrics aren't my strong suit.

Yeah I had it figured much the same. I think the dominators are more powerful than the bestva (who thinks of these names) but was struggling to make 100% sense out of their adverts :oops:

I think the dominators are around 600 watts without the dc fans. I can't get any accurate info on dimensions or optic degrees to guess on the actual footprint.

Wait... a 2.4 meter x 12 meter tent? That's enough space to run fourteen- sixteen 1000w de HPS lights.

I must be wrong, can you clarify the space you are using?

If using a gas heater you could benefit from the co2 it produces that would probably increase yield more than adding hps lights
