Questions about useing Gavitas in tent....

[Dadioski]

Monster Gardens does a lot of the beta testing for Nanolux. The independent test results I've seen show a slight edge Nanolux has on Gavita...although they are very close.

Also, DEs are designed to work in tandem with other DEs. The secret to DEs and their increase in crop yield is not just about the lumens or PAR value, but rather the fact that the hood is designed to work with other lights. DEs produce what's known as horizontal light penetration in addition to the usual vertical penetration most are familiar with. This interlacing of light patterns increases the light penetration deep into the canopy by entering at multiple angles, averting the leaves that block vertical light.

Companies are coming out with hoods that will do a 5'x5' solid footprint, but this will simply be too much light for such a small area. Way beyond the plant's ability to utilize that much light.

People that have tried to use it as a single light will mount it closer to the canopy. This is analogous to making the footprint more concentrated with a new hood designed to do so. What happens when someone does this is that the plant starts to bleach, and if the light and heat are concentrated enough into one area, the plants shut down completely.

If you decide to use a DE in a tent I would seriously consider buying an air cooled hood like the AC/DE hood from Sunlight. If you use the open reflector, you will end up spending just as much money on ventilation each month as running the DE, and there's no guarantee that this will even work.

I agree with above, too intense for a tent without additional cooling.

Yet thousands of growers use them successfully to grow 1gpw commercial quality bud in tents and single bulb closets without "additional" cooling.

You're also not supposed to cool HPS bulbs, air cooled hoods significantly reduce the light output, from both the glass and the temp fluctuations.

Well said on the light from different angles for better crop penetration though...

Well goddammit after Sativied's post, I recant, it was my judgement, based on my room with a shit load of other heat sources, so, forget what I said, I do not have a tent and do not fucking know. The DE fixtures do run pretty cool, the plasma's are a major heat sink though.

 

[FamMan]

What do you mean heat sink??

 

[Dadioski]

I mean they the plasma ballast get pretty warm, warmer than you want on your skin for more than say 10-20 seconds. The ballast get much warmer on the plasmas than the 6/750DE ballasts. The light emitted from the plasma is cool where most of the heat from the HPS DE is in the light and the ballast remain fairly cool. If this makes sense.

 

[FamMan]

Yes it does. I didn't know that about plasmas. Thank u.

Hey guys!.. Just my two cents.. I recently upgraded my gorilla 4x4 with 2ft extension making it 8'11" tall.. I bought the 6/750 flex w/EL2 controller..I also added the new can max pro 6" multi flow fan(awesome)that I have turned all the way up to 420cfm hooked to a 6x24 phresh and its blowing straight outside.. My temps are sky rocketing.. At 750w it will run about 9 degrees warmer than bladder room.. So I added a 4"vortex inline blowing air inside at the bottom which helped a bit. Needless to say, my hut runs about 79-84* at 600w.. 750 just runs to hot.. I run it at night and temps have been cool around 45* outside.. We've had nights that only go to 65* and the hut will get to 86* until the el2 starts backing it dwn.. One wk away from chop and I do notice a more outdoor look to the buds however I think heat stress made my prefaces throw huge bananas that seeded everything.

Good info. Thanks for your feed back. Sorry about the heat stress.

Dude thanx for the info!!!! sorry to here that about ur grow. so are you goin to try and change ur setup or tweak it?

 

[TrimmersDlite]

Thanks mfrog.. Shit happens.. It was only one of the two phenos that did it and thankfully the one I'm not keeping.. Moving next month and I want to run two flex Gavitas in a gorilla 4x8 but I'll def need to run at same time with a window ac unit in window running the whole time w/lights on.. I want these Gavitas to work if you can't tell..

 

[TrimmersDlite]

Thanks famman.. Yeah if I have to run the two lights on flip schedules I'm not sure what I'm going to do cause I don't want to run ac 24/7.. We had to quickly get in and get out cause rental company was supposed to give 24hr notice and didn't to look at it.. So of course I forgot to look if breakers were in place so I'll find out next month what I'll be able to do.. Also, sunlight supply rep told me about issues w/ indicator lights not working on some units.. My flex ran for a month and shorted out blowing my breaker.. Thank god I had another one and shop just rma'd it but there's no stock out there to replace atm

 

[FamMan]

hope you get dialed in on ur next run. really appreciate the info.

Solis tech rep came in and spoke about the issues they've had over the last year with the ballast, New mfg plant was the problem he said.good news I hope cause they were good at one point.. He also showed my buddy the new DE bulbs they have and one is a finisher bulb that looks like it wrks pretty well.. Kinda cool for the DE peeps
