GAVITA PRO 600/750e

If u had your choice of either the Gavita or an Area51 pw150 for my situation which would you prefer? They're within $200 on price so the difference in cost isn't that much of a factor

That's comparing professional horticulture lighting to a toy. But do you have the space for the gavita? If too small the A51 could actually be a better fit.

They are very commonly used in tents, the ballast doesn't create as much heat as people assume, and it doesn't have to be at a higher difference either. 10CM/4inch per 100watt has always been the standard, that's how you get an even spread for a corresponding space. So 40cm/16inch for 400watt and 100meter/40inch for 1000watt. Simple.

Are they better than Solis tek double ended fixtures?(sorry to hijack...been wondering which is better and I didn't want to start a whole new thread)

Hard to say since I don't even know that one. The Sun System AC/DE Double Ended Air-Cooled Reflector 8 inch is according to a test at growershouse.com better in terms of par than the gavita, but overall Gavita fixtures are simply the best in the world. Not toys for mj growers, we got greenhouses with thousands of them.

The 600/750 is specifically designed to close the gap between 600w and 1000w, to allow more options for greenhouses, not closet/tent "hydroponics" like the many cheap chinese manufactured knockoffs selling streetlighting. Unlike some others it doesn't have fans, yet can be used in extremely high humid areas (greenhouses) and doesn't overheat. That's quality material+manufacturing.

But I am seeing better results @ 825

Right, that's kind of the point of the 825w setting, save watts when you can get away with, or better use, 825 instead of 1000. When you got hundreds or even thousands that makes a huge difference. Same thing with the 600/750, it basically allows you to avoid using 1000w for a space that can use less than 1k but more than the 600. Good chance it will be my next light setup.

Guess I should have asked are the gavitas better than double ended lamps? Seems like those are the two top choices when it comes to indoor lighting.

No, that's not a better question honestly. Since the best gavitas are fixtures created for the best and original Philips DE lamps. The 1kw philips DE bulb is a little better than Gavita's own, or was, dunno, not keeping up. Their output is higher after a year than the knockoffs start out with so...

I'm in a space that's 5x5 with 8ft ceilings(walk in closet) and from what I've read, the Gavita may be too much for the small area that's why I was curious about the LED...

chuck estevez said:

no sir. when they have a plug and play that is proven, I might look at led, but it seems the DIY led is working for some and I don't want to experiment with them when the gavita is working so well. Leds would mess with my feeding and temp/humidity of my room.

Thank you for the great insight, it makes me feel much more confident about purchasing a Gavita!!

You are right not better question....actually kinda stupid...I forgot the gravitas are de too. Thanx for info. Definitely will help in with my choice.

That - with a proper exhaust - is a perfect space for a 1kW gavita and will surely be enough for a 750.

So what's the bare min size tent or area someone could safely operate and cool a 750 gavita? 4x4x8?

I was wondering this myself. May have to stick to my toys for now. I require space!! Don't we all....

Good topic guys

Bare minimum is roughly 3x4x6. That's 1' in height for the light itself, 2' distance to plants, 1' for pots, 2' for plants. That requires cropping or running short fast strains in a sog, and a proper exhaust in any case.

4x4 is more ideal for max yield of a 6/750, a few weeks boosting to 825w. 4x5 or 5x5 work fine too though, a good setup running a 6/750 on 825 can do better than a poor set up 1kw setup. If I were to build a closet/space from scratch I'd go for 4x4.5x7.5

8' height is plenty, so is 7'. (8' already allows for 4' plants excluding 1' pots).

Well stated my friend, thank you!

You are joking . . . .sorry this is wrong information!!!!

I can lay my tongue on the integral ballast of the 600e SE when they're at max, for hours , if I had the time. THE coolest running, (non vented) 600w HPS, imho!! The bulb might be your problematic heat source, definitely NOT the ballast!!

I run two of them in a 2.4 x 1.2 and the growth rates are off the charts . . . . and cool as beans, my 4amp SMScom Hybrid, never clicks up out of 3rd gear!!

You can count on keeping a cup of coffee warm/hot if you put the cup on top of the attached ballast.

Got something here to back up my reactions . . . .

A reading from a laser temp. thermometer on a Gavita Pro 600e SE, at full pelt, has been for three hours . . . . .



I can NOT drink coffee at this sort of temperature!!!

Lets not forget too, this ballast is inside the grow tent, it's getting residual heat from the bulb just inches away too . . . . . cooooooooooooooooooooooool running!!!! MAKE THE RIGHT CHOICE . . . lol

Bit more proof . . . .

Here's a reading off my Lumii 600w that has been running for just over an hour, OUTSIDE the tent, under a window that laps cool breezes over it!!



Sorry, bad light, but that IS a Lumii 600w at work in the background!! Word up!

Hey also, depending on your budget, and the fact you've already made you're mind up for Gavita , try to afford the EL2 controller.

If the Gavita Controller finds that your fans are just pussies, and can not cool yr closet it will dim lights for you until required, user set, temps are within limits again, if it's just too darn hot, it'll shut down for you all together . . .

The even more expensive option are the Modules, then you can run other things with light on or off, i'e' air con when lights are on, or a heater / humidifier when the lights go off . . . . .


Hope I've helped

Gravitas just oook awesome!

They bloody rock @oill . . . . .

Gavita have not missed out a thing with user friendliness. Their EL2 controller can govern up to 80 lights in two different rooms!!! Turn on AC or Heating at lights off or lights on.
You can program Sunrise and Sunset over a 1 to 30 minute interval. Great for foliar feeding before bedtime, or just before full boar flies in!! (Also great for sorting my ventilation out over 30 minutes, I have to open and close certain windows at lights on and off, the 30 min run up and run down, keeps an exact temp in my tent (Also thanks to an SMScom Hybrid 4amp fan controller)

If you are thinking of professional horti lights, I'm pretty sure I'd not go else where. I've seen light reading online that strip epapillon or what ever they're called!!

Check this video, it's about LEDs but the medical MJ grower in Cal. takes readings from 6 of his Gavita 1000DEs, the readings are far better than the other lights; except for the Spyder LED set up, !!! AWESOME!!!!




Grow on

That test is not fair... You might use the gravita that far away for pansies in a greenhouse, but you would use it closer for our shit right??

Life's not fair....

Well that video IS promoting the Spyder LEDs.

The point is, when MJ is ripening, (the stage the plants in the video are at) pro growers tend to raise HPS lights to reduce heat, . . . . .so the point of the LED promoting video is that the LEDs do NOT need raising to bring temps down for good ripening . . . you follow me bro???
