    Tactically if your going vert. Drop a naked 315 in the center of 4 plants. Use all the bulb and get a bumper crop. If your gonna Scrogg do two plants and get a cob and still get a bumper crop... I'm biased to the first option but style will weigh heavy on this decision. You won't loose either way. As many opinions are out and both techs are solid. Both will get you great meds both have an entry and learning curve and with that space allotment your style may be predicated on budget. I've seen the cob stuff do some pretty amazing things and like a lot of the old timers still a little hesitant to pick up the new hammer... happy growing..

    No. But if I had to do it all over again...i would of went with Nanolux. Just for the orientation of the ballast. On my Gavitas i rarely use anything past the 600 setting (Nanolux de only goes to 650 tops I believe) anywAys. Iam working with a 78 inch tall basement. Which is kinda low for any double ended hps but the sixers work out fine. The thousand watters are just too much light. I could dial them down of course but the spectrum isnt ideal when a double ended thousand is dialed down. Hence why Gavita came out with the 6/750 flex.

    In the local hydro shop i could get the gavita 6/750 flex but how Could that be the best option For my 6'6" 4x4

    Could you point me in the direction of fixture that would allow for that vertical garden - i was tossing back and forth between the nanolux and the sunsystem, both are vertically hung bulbs but are both in open hoods..
    Nanolux use's their own ballast
    SunSystem use's the ballast designed by Philip's if im not mistaken...
    i was going with nanolux as its cheeper however i was advised to go with SunSystem as its philips ballast-
    and ill be running the Phillips bulb either way..
    a naked vertical application would be great, im wondering now what that raidious would be from bulb to plants?, Make a cage out of chicken wire to hold plants back off bulb?

    Im inclined to try both methods; i can already see watering under this trellis net may become painful, its bad enough haveing to have the plants on the floor, but from what I've read and im dyslexic, guys are saying the net is the way to fill out this 4x4

    I think I'd rather have full acess to the plants, could pull them out and onto a table if need be,
    maybe Vertically is better suited to me

    this would then give me 4 times the space to fill? Im new, but im thinking my needs will leave me aiming for a pound per harvest.

    Get a 25 ft cord set.. gives more options for ballast placement...
    Mogul adapter ...
    3100k Phillips ... the one they sold me was open rated so specify... I learned to check..
    Plug and play....

    Its not the best option if its the only lamp. A good one but Gavitas and the rest of the attached ballast double ended fixtures were meant for commercial grows....using multiples of them. The overlapping and crosslighting is where they excel. And why the ballast is attached and orientated the way it is...less shadow and easier to maintain in a greenhouse...when you have to install and service hundreds of them. In your situation and most home hobby grows i would go with a thousand watt air cooled regular lamp...a couple lec 's from Sun Systems or a 600 watt double ended with remote ballast and hobby type reflector....but i forewarn you....even just one or two of these get HOT. Really hot. And you can be assured yiur going to need supplemental air conditioning...even if yiu think you dont because its winter right now. If yiu plan on growing indoors in a small space...with double ended lamps 365 days a year...plan on installing some kind of air conditioning. Thats why single ended hid lamps with air cooled hoods still have a purpose. Ive seen kids cramming double ended lamps in tents with no a.c. and honestly i dont know how they do it. I do know why though. They "hear" its the best lamp out there and thats only true for some situations. Double ended lamps with attached ballasts are truly meant for commercial applications...high ceilings...and in high numbers. Remote ballast ones (like the giant air cooled hood trend just a couple years ago) is just the hobby industry catering to what hobby home growers think they need.

    I have a 1000 Avenger DE fixture. All the research I have done shows it will work in it. I just have to dial my Galaxy ballast back to 600.

    I have three of them, i posted about them just a few pages back.
    My light meter shows them to be just as bright as my sunlight 630's.
    Just fired them up a couple weeks ago, so I don't have a complete review yet. So far so good though ;-)

    Thanks for the info Aero. I have been considering two 315s but am not into spending that much money right now. So a 140 buck bulb swap seems the way to go.

    Growershouse is probably your best bet for the 315's, I've looked around for them in Canada and best price I could get up here was $700 CAD. For COBs there's a company in BC using Cree 3590's with decent pricing, probably even cheaper than DIY kits out of the US.

    If they don't now they've stopped, I bought 2 from them there about 6 months apart. Another was https://www.bghydro.com/ I bought a bunch there for my son as they had a better volume deal.

    Here's an update. Week 6. Blue city diesel and blue dream. Vegged and flowered under the same lights their whole lives. I do veg with the 4200k bulb though. 5 630 Dimlux on the Dimlux maxi controller.

    Hey ganja...did you ever use that same room with Hps de lamps? And if so what total wattage did you have? Looks damn nice...any lamp.

    I haven't. But next crop I plan on putting a row of 3 of them down the middle of the room to see if they really make that much difference in yield. Luckily I have 36000btu so I can play around with that.

    So lec lamps whether 315 or 630 fixtures still kick out heat...of course. But would you say in comparable wattage to single ended (non air cooled) or double ended HPS that the heat load is much less?

    By far. On average a 630 LEC only needs 2200 btu. Gavita claims it's units only need 4000 but it's closer to 5000. You could get away with running a portable AC in a small room for 2 lights. They are no LEDs but still cooler than anything else I've run by a lot. In veg I run them at 60% the room never gets warm. Running the 5 I have now at 10% overdrive and having no problem cranking it down to 50 degrees if I wanted.

    Keep a couple bigger bulbs around to add heat in the winter. Don't have a laser therm however to the hand I would say by wattage standards a 315 feels half as cool as a 600.
