Gavita's are they really worth the price ??

This isnt a normal t5... Im pretty sure youre trolling me now since I found you on the OP that I found this.

I'm not trolling , I have used T5's a lot , there's other ways to get UV light than one of those . My LED room uses one of these. And these in my HID room http://www.eyehortilux.com/products/specific/600w-Hortilux-Blue

Ok I was thinking that you were thinking that they were normal T5s so thats cleared up. But after looking at the spectra graph for HPS they put out a bit more but 430nm and 450nm is what you want and it seems to skimp on those compared to the rest of the graph. 430 (UVA) gets alot where as the UVB not so much.

MH is better than HPS by a bit but still more output from a single T5 according to GE. I would say maybe 8% output of the light at best. So a 1000W MH puts out 5W of UVA and 3W of UVB.

Yeah you really don't want as much UV light as those T5's make, they should only be ran 15 minutes at a time, last 6 hours of the day only. When I started using that 18% UV light I scorched my plants with too much UV, makes all your trics burst and you get a ton of early ambers and couch lock city.

My point was that either way you need to supplement to get the best resin its all about pushing as much as you can for max trike production. even on and off every 10 mins would kill it. Since the plants produce THC crystals as a sunblock it would make sense to slowly add more to make the development go crazy.

If you running COB's i'd suggest supplementing more red (particularly far red) in the spectrum as well as it is highly lacking in that area.

Is this for cobs or all lamps?

I would agree. I plan to run one in between the cob bars when its needed.

All lights.. because even MH has a negligible amount of both UVs.

That's not really how it works, when you use UV light it has a point where you don't want any more . UV light makes your plant grow smaller because it spends more energy protecting itself(growing trics) , and if you put the UV light on too much(or too close) it will burn your plant and scorch your trics and reduce your yield. You are basically giving your plants a mild sunburn. Also when working with UV lights try to wear UV protected sun glasses and limit skin exposure, it can cause skin cancer and damage your eyes.

There's a lot of strains that can hit 30% or come very close (high 20%'s ) my golden goat got tested at 32% at the dispensary I bought it from. My tangie cut is actually frostier than my golden goat and I ran gorilla glue 4 last year that definitely was around 30% it was super frosty.

I personally.do not put too much stock into the testing lab results stuff. Ive seen and have had different labs produce different percentages from lab to lab....different sections of the same plant and whatnot. Its all ballpark at best. Ive seen variances as much as 7% from different labs. Same chunks of buds from the same tops...lowers...secondary buds...etc.

 

[since1991]

I pretty much do not get into the "this bud tests over 20%"....or 25+....whatever. Ive had straight floor me cannabis that tested 15%. Ive had 26% The White strain not even give me a head rush. Thc % doesnt mean a hell of alot to me personally. Just ballpark...money thing..and bragging rights.

I live in Colorado , that pineapple express is a huge yielder I know someone that been running it a while.

I know a good outdoor grower here in Michigan that used to run P Express and it was a very big yielder outside and very top quality. Tasted like rotten pineapple and sprite soda.

Just when everyone thought the hps bulb could not be any better gavita came along with de tech (or phillips)
Im betting since they have unlimited research money now we will see another jump in tech with de lamps very soon

yeah i dunno. that was 5 years ago and were still working with decades-old arc-tube technology which is at its limit. vs solid state lighting which has the advantage of more efficient cheaper semiconductors evolving constantly. HPS may evolve a little bit but LED is pulling away in every respect including rate of unit cost reduction which will make it a level playing field in the next 18-24 mos. i mean shit 2 years ago crees were over $60 for 10000 lumens. now you can buy 40000 lumens for $40 and that will cost less than half of that two years from now

THIS^^^^ is why led cobs will soon be IT. I run 8 Gavita 6/750 flex's now. Have been for a couple years. Didnt know ANYTHING about COB technology at the time. But ive been paying attention lately. And its getting better and better. And lightning speed too. The advancements and tech/efficiency is moving so damn fast. Literally...like as I type...these words on my phone and forum fast. No shit.

 

[CobKits]

its damn near the point that instead of investing $100 in your next hps bulb you invest the same $100 in 1000W of chips that last over a decade at better efficiency

Hi since1991 would like to no what lights you are using for your veg. As I just ordered 6 of the 1000e gavitas with the controller.
And if you use gavitas what are they like for veg

I got a 7x7 tent with 2 8 bulb t5's and a 400 watt old school ballast metal halide in it. I got a very old school co2 tank,regulator,and timer too. Vegges them real nice and bushy. Then i put them in the flower rooms. I got 2 rooms actually. The other one is 4 air cooled 1000 watters. But this room doesnt have the mini split ac and i shut it down during summer months. With double ended lamps...you need a.c. Its pretty much mandatory when running more than one.

Ok thank for that, I do run a few rooms my self and all of them run 600 hps, Next week will start on building a 20x8x9 room. My main grow room now has 9x600hps in it I cool it with 4 big fans most of the time only needed 2. So I was hoping to do the same with even bigger fans I seen ones the over day 2600cfm. Can you use the gravitas for veg or have you ever heard of anyone using them

Interesting because if MH has a "negligible" amount than that would mean that sunlight also has a "negligible" amount of UVs...

(using your 5w out of 1000w as a base)

Realistically if youre going to claim the "need" for supplemental UV you must also proclaim the "need" for CO2 levels to be ~1500ppm.

How in hell are you cooling a 5400 watt room using just fans? Summer months? Wtf???
