Haven't been on RIU in a while. Was hoping there might be some updates here. Hope all is well with the personal operation, Shrubs. Would love to hear some further thoughts on the Gavita as well, since you've had one rocking for a couple months now, I think.

Got some veggies runnin at home. Every time I've turned on the Gavita they just kinda droop and stress out. Gotta wait til
flowering, it appears. They just don't need that much light in veg apparently. No pics as of late.. but i'll see what I can do

Ya that place is pretty big, but nothing compared to some.

Please do answer this; I read this entire thread and I'm dieing to know. In fact I registered just to say so and you motivated me to stop lurking and quite frankly, inspired me to start growing. I'm curious how this grow turned out and curious about your experience with the Gavita has been.

Sorry for delay in response. Last grow of full room of WiFi yielded .8 grams per watt, about 3.2 lbs from (3) 600 watt lights

Really close to your goal of a g/W. Nice.

How about the Gavita?

You asked for it. I tore down the grow I had going at home, it was in a spare office I have and I
had the funds to lease a small warehouse space. Did a pretty serious build out in it. 6,000 watt flower,
all Gavitas.... Here it is almost finished.

Decontamination room: Where we change out of clothes, spray down with alcohol and into chemical suits.
It has a HEPA and Carbon filter and soon will have a UV light ducted in-line with the Carbon filter.


Behold the flower room: It will have 6 Gavitas (5 are currently hanging, and only 4 are on.) over 3 trays
with a max of 24 plants in Flower. You can also see the door from the decontamination room across.


Sink and work space:


Looking at the door to the Veg room from flower.


The veg room: It has four 600 watt lights over six 2x4 trays. And space for clones and starters
at the back.



So far it is going great, as of yet we haven't pulled a crop. Plants have been in there for about 3 weeks now.
Although the flowers were vegged for about two months at my house.

damn shrubs thats a nice set up. i been debating about getting the gavitas as well. my local store has em for 440 each, but at the same time theyre having a deal on 1k quantum ballast with a 1k digilux bulb for $200. With you gavitas do they produce alot of heat? At the moment i don't have A/C or co2 but i have aircool my hoods. For your veg room is it better using 600's to veg than 1k's? Do you use the 600's to spread out the light? thanks for the update shrubs been wanted to know whats been going on with ya. Are you still working with the commercial warehouse?

Your local store must have the 600 watts for them to be $440, those are $400 at my local store. And the 1000's were $600 a piece, not including discount.

They produce as much heat as any 1000 watt. Average of 3.4 BTU's of heat per watt, so 3400 BTU's per 1000 watt. We have a 36,000 BTU AC. So it
keeps it perfect temp. No longer with the warehouse... Again. Luckily my my contract had an exit clause and I was able to use it. There are some shady ass people in the world of business. But I got this spot all to me and one investor and we are looking forward to crushing it. Thanks for checkin back.

The key with the Gavitas is that they run at 240V but convert it to 400V for the bulbs. What a higher voltage does
is increase the frequency of light produced, which makes the light have a much higher energy. Light has properties
of wavelengths, and long wavelengths – wave physics and particle physics are a part of that. Each color of light travels
at its own speed, each carrying a certain number of electron volts; there’s more than one speed of light. Plants want
all the colors all the time. The relationship between frequency and wavelength are inversely related. The Sun is shining
with full spectrum light, at a specific frequency. Higher frequency electronics produce light that’s closer to the Sun, but man
can’t perfectly replicate the sun. The Sun shines in space in the Penta and Terra Hertz, but not all that is received on the Earth.
So we continue to try to replicate it.

Glad to hear the new spot is all yours shrubs. This is the one I'm talking about http://www.sunlightsupply.com/p-14414-gavita-pro-1000-de-complete-fixture.aspx. MSRP they are $599.95. My store gets em for $400 and they charge me 10% above cost. I think if i switch to these i'd have to get a mini split. For veg do you think 4 600's spread out would be better than 2 1000's?

Wow, that's the lock of the century. If you can get a 1000 Pro DE for $440 I'd say jump on it... Mine were 580 after my discount, and
I am definitely at the highest tier of price drops I can get. You will definitely need AC, however, unless you upgrade and get the ducting
they sell for them, it incapsulates the ballast in, essentially, a PVC pipe and allows you to hook up 8inch ducting to them..
here they are hooked up to the 300 LEP's

And I just did the 600's in veg cause I already had all the hoods, and ballasts, just bought all new Halides for them.. I'd stick with them though.
No need for 1000's in veg, too much light in my opinion.

Thanks for the update, Shrubs. Based on your new setup and your explanations, it sounds like the Gavita gets the thumbs up.

Out of curiosity, is that a green CFL I see in the ceiling in the second picture?

Just love the Gavitas... There's no way you can veg with them though.. Even set down to 600 watts they stress the plants in Veg.
Once I flipped em into flowering they perked right up.

How you doing bud?

Hey bro! Happy late holidays. I'm doin great, that last crop pulled down just over 10 lbs. So ended at about .8 GPW from the Gavitas
with NO CO2 injection. I'll get pics up soon, sorry for delay.
