Gavita-Pro 1000w 400v (new generation hps)

[whazzup]

@whazzup ..if u were building 2 rooms ..tents bc of ease and quick dismantle if need be and just overall the beat solution for me ..I don't have a certain # of lights I wanna use but 6 would be max ...4 optimum minimum ..

I was thinking 3 600s in each tent better coverage ..less heat ..less power usage ..do u have a better idea / setup for a space like that ..I can't give u exact floor demesions but its decent size ..and it's gonna be ac cooled in the warmer months ..

Is there a benefit of getting the remote ballast compared to the all in one ..I kno the reflectors have adjustable light spread and it seems like a better idea for a tent but u kno more than me ..

Good looks I'm tryna step my game up lol

The pro-line can not be adjusted, the TripleStar can.

Two more advantages of the complete fixture:

- No EMI
- Easy wiring

As said before, every HF remote ballasts will cause EMI. The ease of wiring is obvious: you just have to bring power to your room, no separate lamp cords. Much easier to install. In fixed environment I would shorten the lamp cords and make outlets close to the hanging points. Easier to change.

What size of tent are you thinking about? What's you're growing style? How high will your tent be? how high your plants? Does your climate allow for open reflectors?

There are so many aspects to a growroom that each and every one deserves it's own topic

3x Pro 600 in a 4x8 works really well! Keep 90 cm (3 ft) between the center of the lamps and keep them wide on the short side (so they will be hanging in-line with the length). Minimum distance to lamps 65 cm (2' 2") for almost 1300 umol s-1 m-2 average and a great uniformity. At 3 ft distance you still have more than 1100 umol s-1 m-2 and at 4 ft almost 1000 umol s-1 m-2 average.

So do know what you are doing, it's a lot of light, but when completely sogged yields of up to 2 kg are possible on this surface.

1.my biggest yields have been in 3 gallon pots but I think 1 gallon sog would blow that yield away ..I did 2 gallons last time but I didn't like it ..for the amount of floor space the 2 gallon takes up the yield isn't worth it ..for me ..this run is gonna be 1 gallons so well see

2.my ceilings are about 9-10 ft

3.my plants finish at 4-5 feet ..with the pot ..but I prefer about 4 and a half it's easier to move and maintain ..

4.a.when I air cooled b4 I pumped cool air from the bottom from a vent hole with a AC
B.I air cooled by sucking hot air out of the tent and tru inline fan ..open vent hole
c.Now I'm air cooling ambiently ..4 inch duct booster pulling cold air from the bottom lights on and lights off ambient ..with fresh air being pumped in every 30 minutes on a timer depending in the temp maybe 1-2 hrs


Thanks for that info u really helped me out ..I'm gonna use that tent size u suggested ..it should fit no problem ..

The triple star is really cool to me and being able to adjust them to over lap or penetrate deeper in the tent seems kinda cool ..I'm not really worried about the EFI unless its enough to interfere with other people's homes ..and I think if I shield them and put them in a good location I should be ok ...the cord situation is annoying that might be the breaking point but I'll see ..I'm a neat freak tho so I can make it pretty

Thanks again ..

Excuse me whazzup, but these amounts of umol you mention here seem to apply to the 1000W and not the 600W from all I read before. Is this a typo of yours?

[whazzup]

3x1000 = 6000 umol s-1 / 2.88 = 2083 umol. So it is certainly not a 1000W calculation

3x600 = 3427 umol / 2.88 = 1190 umol - and that's without wall losses! So yes you are right about the levels, that should be lower. I think it's data I copied from a wrong calculation table. For uniformity and average levels we normally discard a small strip near the walls in the calculation, as the walls always have a huge effect on the uniformity. So the center sometimes calculates a bit higher than you would expect, but not that much . Thanks for noticing!

Recalculated it with 85% reflective walls (bit less than the average imho too high specs):
distance from reflector - ppfd avg:
65 cm - 1060 umol
85 cm - 945
105 cm - 860
145 cm - 700

That is much more like it, I must have had a different lamp in my calculation last time. Well it's always night work when I post here - I do make mistakes (fortunately it is a human trait) so I'm not a reptile

so at 65 cm in this configuration you lose about 10% due to wall losses. That's also a result of how I configured the lamps in a row, so long end overlapping instead of short. Lamps shine to the wall for improved uniformity. 1.2 meters is too long for the short side.

Bigger rooms = smaller losses.

Hi whazzup, I'm a proud owner of 1x1000W DE fixture and i'm thinking to buy a light rail sistem to cover efficently my new grow room (2*1.5*3h). I'd like to put 1m rail in the centre of the ceiling and let the fixture go left/right.... will you give me some advice, please?

thanks

I just saw a thread at a different site where a guy did really well
over a 4'x8' with a mover. I found the thread by googling Gavita-Pro 1000 sog grow.

 

[noyd666]

found this , made in Russia,lol ses gavita. but it has inbuilt reflecter? this one 600w. sale in oz probably like Russian cars.

 

[whazzup]

We introduced the Gavita IR lamp, made by Reflux, many years ago. There is a huge difference between the Reflux lamps and the Gavita IR lamps, which is the arc tube. We use a horticultural arc tube in our lamps, not a street light arc tube.

It's a great design but it does need what we call a dew guard, shielding the top of the lamp from falling water. Also the lamp holder is a bit different because when used in a normal lamp holder you would risk touching metal. So use the official dew guards for them.

Many old-school growers here in Holland don't want anything else, and also our trials have shown great results with this lamp. It is really extremely wide, resulting in a better heat distribution, the lamp is not in a reflector so it can be cooled better, the reflector inside the lamp never deteriorates because it is in vacuum, the light only goes through the glass once.

Rambridge sells them in Canada.

now I understand why mine exploded, did work great though!

Sorry after I saw your post I went and checked the box it says gavita nowhere so it must be a Chinese fake and yes I ran it in an e ballast!

 

[whazzup]

The old/standard IR lamps were/are not suitable for high frequency electronic ballasts. You really need a lamp with a suitable burner. There are many copies of this lamp, some even with optical a bit better glass than Reflux makes, but it is the burner that generates the light. Don't fall for cheap Chinese copies, but hey, that's a given, right?

We are even experimenting with a horticultural 400V arc tube in this lamp, which has about 8-10% more output. But the problem is always market acceptance, you need quantities to make this concept work in a market. In Holland we have a very steady customer base for these lamps, specifically in the low wattage (250-400W) as they are really wide and very suitable for those types of grows. Great results, but again, don't take my word for it, look at the results your peers get.

 

[willyweed]

hey whazzup could you give me a firm price in euro's for the 1000watt 400 volt light kit if i brought it in holland also where from?.i will be going to amsterdam but also have friends in nijmegan ? many thanks .willyweed

Hey guys long time troller first time poster.
Swapping out some noisey digital ballasts with 4 gavita 1000 w all in one units.
Old setup was 600s = x and 1000s = 0
x 0
0 x
x 0
0 x
All on top of a pot pretty simple. The 4 0s and going and got 4 gavitas to put up there but after firing one up found the spread is really totally different to anything we had noticed before.

Any ideas on the optimum setup for a 2.3w by 4.3 L by 2.6 h room would be to incorporate 4 x 600w batwing standard old school lights with 4 of these new things? or if it has to be buy more gavitas as its to late to return

Ive managed to gather the gavitas spread 920mm by 1530mm and was planing to put the 600s in corners and let the gavitas over lap length way of the room but feel being 2.3m wide and the short side of the spread hitting 1.8m it may be a no go and should of researched this before running out and purchasing.

Playing around I feel it has to be really close to the wall to light up the pot maybe say 50cms or so looks ok and doing the same on the other wall leaves a gapping hole in the middle where well ya know is where all the cream is......

I don't really understand umols and all the earlier stuff discussed its over my head but the ratios lost at different heights i managed to grasp. The old lights done really well 40-60cm above the canopy. These things the talk around seems to be 60-70cm above canopy @100% so my question is what about early on if they are at 75% (750w) do i workout 75% 60-70cm to get me in the right ballpark? will they streatch if left at 65cm @1000? time will tell but any help along the way is always appreciated thanks in advance to anyone who takes the time to step in and throw a dog a bones.

 

[whazzup]

@Willyweed: For the 1000W el lamps look on the negative the Dutch shops, we don't make the prices of course.

@burbman: I'm sorry but I can't give you any solid advice based on a mix of lamps, as I do not know the output and do not have the reflector data for a calculation.

 

[Burbman]

Thanks whazzup I understand that you can't give ballpark estimates on things you dont know anything about etc
Can 6 of these units be used in this space at 1000w scrapping the 600s all together or would you suggest more units running at a lower wattage for optimum spread and over lap for uniformity?
Im assuming 6 units would spread long side of the room end to end. Then say 8 units would start spreading short side to short side at 750w a totalling same kw per hour usage. Just double the investment i have already made.
The shop owner has suggested I can go with 6 for around the same results as I was getting with a power saving of 400watts. But i am sceptical about not having a light over a plant call me old fashioned or narrow minded but im trying to see the bigger picture but have my doubts the guy in the store is guessing as much as myself and for the $$$$ already spent wanna get it right.

 

[scrulifson]

I figured I would chime in since I havent really found anyone that has used the gavitas and actually documented it through out their grow. I currently have a grow journal on roll it up if you would like to follow along. If there is a grow journal section on this form I will make one here as well. If anyone knows how to make a journal on here I am all ears!

My set up:
- 11 Gavita pro 1000's
- 5 ton A/c
- 105 pint dehumidifier
- co2 burner
- Sentinal co2 controller
- Crestron Full automation system
- Stealth 200 GPD R/O
- 12 Wall mounted fans

The Plants:

Now for whats actually under the lights. I am running 9 plants per light. About half of them are Tahoe OG and the other half True OG with two lights of mixed plants which include Sour Diesel, Gods Gift, Massive OG, and one Woody OG. I will be starting 12/12 in about two weeks when the room is fully completed. They have been veg. for about three weeks in 1 gal pots and are being transplanted into 5 gal microkote pots this Thursday to be flowered in. Most of them have been toped and have 4 main branches.


Medium, Environment, Nutrients:


- Soil: A blend of Sunshine #4, coco, and perilite
- Temp: 74-82 degrees (day), 66-72 degrees (night)
- Humidity: 40-50%
- Co2: 600ppm (veg), 900ppm (week 1-3), 1250ppm (week 4-6), 900ppm (week 7- finish)
- Nutrients: Earth Juice; Grow, Bloom, Micro, Catalyst, Meta-K, Oily Cann. Great White beneficial bacteria (every 2 weeks), Vermi-T (once a week)

 

[whazzup]

@burbman: fire a question to Gavita Holland Support on how you can utilize the gavitas best in your space, we can not guestimate any combinations. So do one part how Gavita recommends it and the other part with your other lights, makes a better comparison too.

@scrulifison: sounds like a great setup but on what surface and how do you plan to get uniform light out of 11 lamps?

 

[vwgtiron]

Wazzup
I may have misunderstood. I have included a schematic drawing of my room. I currently am looking at the lights and wondering if I have screwed up. I hung 2 boards on the ceiling to hang the fixtures from. The distance in between the lights from the middle of the light bulb is 8.4 feet. This puts me 2.9 feet away from the wall. Are you sure this will make the most even light spread? Also you said to hang 10 fixtures in 2 rows .95 meters apart. In conversion that comes to 3 feet. I cannot hang 5 only 4 unless I hang them closer together. 4 puts me 3 feet from each wall and 3 feet in between each fixture. The height of the fixture is 8 feet 8 inches.

 

[ak-51]

I can't remember if I asked this before so I apologize in advance if that's the case.

What is the total height of the 1000 pro unit? I see that 13.4 inches is what is listed on the gavita site. Is that from the bottom most part to the top of the eye bolts, or just to the top of the ballast? I'm asking partially because one of the schematic drawings I saw on the site does not show the eye bolts.

What is the minimum recommended distance from the bottom of the unit to the top of the canopy?

As a side note I was told that my hydro shop would not be stocking these any time in the near future because their profit margin on them is very small. They will however order them, which is good enough for me.

I was told that the light degradation on the bulbs is much less over time than with regular 1000w bulbs. For those people who are running these, how many runs are you doing with one bulb?

 

[scrulifson]

@whazzup Im not sure what you mean by surface, but I have 5x5 painted wooden platforms about a foot off the ground that the plants are sitting on. So for each light there is a 5x5 platform to make sure I am getting the proper distributions to the plants.

 

[whazzup]

Guys distances are NOT between fixtures, it is between centers of lamps. Distances from lamps and light maintenance/reflector/lamp changes have been discussed numerous times, please read. Light pattern is NOT square, nor is it from any horizontal fixture.

1000w 70cm+
1150 80cm+

Large rooms with overlapping lights 100cm+

At the sides of your room the lamps will hang much closer to your walls of course, it deals with wall losses and the fact there is not a next fixture to create overlap. Take a look at some room calculations published.

 

[Twisted pleasur]

Good information Wazzup been reading all ur posts. Im going to do my calculations today. Hope I can come to a compromis between heat,electricity,and intensity for my space.

After seeing my first gravita the other day in person. I was sold.

Thank you.
