Calling On Gavita Users

[DankyPanky]

The footprint of a 6/750 is about 4'x5'.I use 6 in an 11.3x11.3x8 room(gavita told me to use 8).Two rows of 3 along each wall leaves me a small walkway in the middle

I switched gear last year from traditional 1000w setups, and now I run 3x Gavita 6/750s in my flower room (which is approximately 12'x8'x9'), and each light gets a footprint of around 4'x5.5', with 6x plants under each in two rows of three. They put out a ton of light, and I like the features of the controller too, with its temp probe, ramp up and down times, auto dim settings based on temp, and more.

With the three lights set at 110%/825w the flower room gets up to about 88* if I don't vent the heat (basement, mountains), but I run an 8" exhaust line up along the ceiling with an inline fan to keep it down to manageable temps and it works fine, plus four fans to move air around (2 wall + 2 box). May have to take additional cooling steps as summer approaches, but I'll cross that bridge when it happens.

Then I run a fourth 6/750 for the veg room. It's on ratchet straps and not connected to the controller (the three in the flower room are mounted as close to the ceiling as possible and never move). I start each cycle with the veg light at 400w and down low then raise the light and its wattage throughout the veg cycle, so that it's at 105%/795w when they flip and see 110/825w% in flower. The extra light that spills out beyond the 5x6 veg area is also enough to light up two 2x4 trays where my clones and babies and mothers are.

Heat is the only issue, and it's manageable. They are very impressive lights, IMO. If I'm able to expand this year I'll get some of the 315w setups to supplement these, and to better control heat and get that Philips Blue spectrum, too. Theyr're the only thing I've seen which compete with the Gavitas. Also, presently, I run them in 110v mode as I haven't yet had some 220 ran. Works great at either voltage.

How is your yield now compared to the 1ks you were using?Im going to be adding some 315s in later this year also.Im playing with a gavita reflector in my shop to try and kind of tweak it into an adjustawing type flat reflector to scatter more light.I got this idea when i saw capulator run one with no reflector at all in a bare bulb room a couple years ago.Im thinking it will lessen the intensity directly under the reflector and spread it out enabling you to get the lights closer yet cover a bigger area.I had alot of luck with Awing rooms before gavitas came along,trying to combine attributes of both and just play around a bit,can do that now that its all personal use,lol.Wish i could just air cool,im jealous of that,best of luck danky.

I remember there was talk of gavita offering different hood patterns for their fixtures.i wonder what happened with it?

 

[Randog3]

I don't see any reason to use a different hood so long as you have the height. I have 12' ceilings and wish I would have gone 14' but the light spreads very good imo. I run 1 1000w gavita per plant. 24 in 20x45 rooms. They absolutely crush 1000w bare bulbs I used to run.

They've been on their website for a while, haven't seen one in person.

Are you talking about the hortistar reflector or for the stardard gavita setups?

 

[fishwhistle]

There are LOTS of reasons for different reflector configurations,there is no such thing as 1 size fits all.Im not sure why gavita or some private enterprise has not jumped on this yet?
Check out all the reflectors PL lighting makes for their fixtures.

Great point.wish I had options as far as reflectors for my gavita..recently sold my gavita flex pro 6/750 de,,but I'm gonna buy another asap.best light I've ever used,and the gavita 1000w is over kill for me unless I have 20' ceilings.never used my 6/750w at full strength. Failed down to 700-750w was more than enough,on a rail too.the 750w daily up to over 800w

This is only my second batch using this setup due to a big gap recently, but so far it seems the yield with 3ea 6/750s running at 825w/ea (110%) in flower is equal or better than that of the 4ea 1000w hoods I used previously (a mix of Phantom and Solistek Ballasts and 8" vented Blockbuster hoods, Solistek HPS 1000w bulbs). It uses almost 25% less power, has a better (IMO) spectrum, and the plants seem happier overall. Anecdotal for sure, but that's all I've got.

And the strains in this period have primarily been Rare Dankness's Tangerine Kush, Reeferman's Cherry Diesel, @homebrew420's GSCbx and DPEX, and @NaturalTherapy's The White x G13/HP, with various other flavors scattered about as I work through narrowing down my list. I have a batch in flower now, 14days in, so there will be another fresh group of results in June-ish.

Hey look what i ran across at growershouse,Gavitas first new reflector!Guy i talked to said more to come,this one is for tents/small rooms i guess.

[sixstring]

Pretty sweet.wish it wasnt 75 bucks for 2 bucks worth of aluminum. But ill probably buy a few to try so they got me i guess lol.

 

[fishwhistle]

Small room reflector

wide 150 degree reflector

 

[fishwhistle]

Lol,I hear you on the price but i bet they go down to the regular price once the ''NEW'' hype wears down.The wides are only 55 if that makes your ass feel any better.

 

[sixstring]

The 150 wide hood looks like a epap knockoff.i like that 110degree though

 

[fishwhistle]

Epap is what i thought of too.Wides are kinda cool though if you have lower ceilings or want to scatter light or decrease intensity as plants get taller,would also be good over scrogs.

Looks like you guys found them. Also on the Gravitas website under proline reflectors. And yes I like misspelling the company name to sound like the next new Taco Bell entree. Nanolux has one like the deep version that also comes on the 630 fixture.

gravitas is an actual word lol. some serious fixtures :)

I was envisioning something like a triple size mystery meat burrito dipped in liquid cheese then deep fried, comes with unlimited free energy drink refills. And for those with serious cojones, it'll come wrapped in a six egg omelet and called Heuvos Gravitas.

 

[friend]

Just put up my first givita 6/750 flex :) probably
One of the best investments i have ever made, my future is so bright, i have to ware :cool: no joke these lights are bad ass .

Finally got my first run out with gavita 1000 and the yield was so sick I'm getting gavita tattooed on my dick. Only issue I'm having is I run the same strains in another flower room with standard 1000 single ended bulbs and every digi ballast brand made and the quality is much better under standard bulbs. Yield is 2-3x more with gavita and quality is decent but I'm unable to get true fire out of the strains that are incredible. Any idea why that is? Does it have to do with plant size or spectrum?
