What would you pick led or hps?

I'm currently running one 600 watt hps setup in my 7ft x 2ft grow tent, I mean my closet. One light is not cutting it for me. I was thinking buying another 600watt hps setup and just run them both at 300watts go up on watt from there till circuit pops. I'm limited to power wattage. My vary first grow light I ever bought was one of those led blue an purple light that was trash. I was thinking trying leds again. I was thinking buying Mars hydro ts1000 or Ac infinity Ionboard like 2x2 or 2x4. If you use an led light what brand and how do you like it?
 
I use, or have used kingbrite qb288 240w, mars hydro fc-e 4800, and HLG 600 rspec. I would go led instantly! Your power usage will drop significantly. And one unit (matching your closet spacing) would do just fine. What size did you say? 7’W, 2’D and how much height?
 
I think hps produced better flowers. For me LEDs are all around easier to work with and much more cost effective. I have aglex(440 watt Chinese bar lights) and hlg FR 600watt. Both lights produce great flowers. I’d say the bar light is a better spread but I like the qb’s because they give me more space at light level for fans. I’d also say hlg has better canopy penetration. IMO a par meter is a must. And start slow it’s easy to fry them.

Did a touch of research, how much you looking to spend. If your space is 7’w then maybe a mars hydro SP series. The 3000 is 300w actual draw for 249 each. I believe they have dimmers. So two for just over 500 would cover your entire grow space with enough power to expand space, or replace with a tent…
 
Than you for your response yes grow tent is 7ft W x 2ft D x 5' 6" H. I can gain extra 18" in Height that require taking the shelf out of the closet building sturdy frame.

I love AC Infinity products…except their lights. The only reason I would recommend one of their lights was if a grower was insistent on having "total"' integration of their light with the rest of their grow. AC Infinity has done a great job in that respect. On the other hand, the spectrum that they've chosen strikes me as strange and the light output is markedly lower than many other products on the market. I believe that what works to their advantage is that most growers don't give their plants all that much light and they've arrived at the understanding that it would be a poor business decision to design and sell a more expensive product that will not be used to its fullest.

If I were growing in a 2' x 2' tent, I'd go with the Vipar Spectra XS-1500 Pro. It's a stunningly good product. In a feature comparison, I don't know of anything in the market that can touch it. Price, vendor reputation, and spectrum are good but what made my jaw drop was how uniform the light cast is. Vipar rewrote the standard.

Check out this review.

[edit]
7' wide or 7' tall?

A 2' x 7' tent will need a much bigger light. In rough terms, input wattage of 30 watts per square foot is the minimum and 40 watts is better. Cannabis yield increases almost in an almost linear manner as light levels increase until you hit the light saturation point.

With a grow space that's elongated like that, you'll need to have multiple lights "in a row". Funny, I was thinking about that last night for my 2' x 4' - three XS 1500's, nose to tail, so to speak. Vipar sells two 1500's joined with a bracket. It's called the XS2500 and it's $200 on the 'Zon with a $30 coupon. You could do one of those + a single XS 1500 Pro. That's only 32 watts/sq ft but it's also just over $250. Maybe go with 4 XS 1500's? That's 600/14=42 watts/sq ft and you're rockin!

HLG is having a sale. Add $20 in wire and you have a 600 watt hlgFR that will fit great in your 7x2.

That's a R spec which is red heavy. Plants grown under red heavy lights (the R specs, HPS, and Growcraft flower lights like I have) will be taller and have longer internodal space. Low levels of blue//high levels of red mean that you'll tend to see less stacking in the colas and will have significantly taller plants than if they were grown under a white LED.

I'd add in a Rapid LED Royal Blue puck and fill in the blue part of the spectrum. One of the mods on another cannabis forum does that. He runs a Growcraft 600 watt flower light + two Rapid LED pucks.

Or just get the XS 1500 Pro since it has a good spectrum and a staggeringly good PPFD map.
 
Well somebody decided its needed in grow lamps to activate something because uv alone isnt good enough
I got 10 diodes in mine fells like nothing but....

IR ≠ far red.

There's discussion about how best to use far red and, as I understand it, the ratio of far red to red is important. Bugbee has some info on this.

In contrast, when IR radiation hits organic material it makes it warmer. That's why room heaters//space heaters are used - they warm things up. Heating live plants has an immediate and negative impact which is why HPS, and other lights, have to be kept so far away from the plants. Conversely, the fact that LED's do not heat plants the way that HPS does is one of the many reasons why so many companies have moved to LED.

If you have evidence that IR can be used by a plant for photosynthesis, publish your research.
