CannaWizard's (AMC) Lounge

Be careful with foliar sprays and ripening issues h2o + co2= carbonic acid!! I have burned holes I leaves before with theemitters hosing a wet spot...

I will takepics tonight but some mj does not want to stop putting out new growth with too high co2 for my varietals it is when I am above 2000ppm the new growth looks strange got sum on my bluberry cuz it is ultra sensitive but the nugs are huge!!

Phillips HPS 400V

Lumatek's new ballast will enable growers to run highly efficient 400V lamps on 230V power.

http://tinyurl.com/yjzx2dk



Lumatek is in the process of developing a new 400V professional ballast that drives the professional Phillips HPS 400V lamp, but runs on normal 230V. Gavita, a leading European horticultural lighting company, has teamed up with Lumatek to develop and bring their products to the indoor gardening market. Industry insiders concur that this allegiance is great news for growers!
The 400V bulb, which is more efficient, performs more consistently and lasts longer – and it has an enhanced spectrum. Even better: it was built specifically to run on electronic ballasts.

They have the plasma and the Philips HPS high voltage unit...


Chameleon has discontinued the very expensive led supplemented model...


So far I like CMH+HPS+T5 Aquarium Tubes+Mega-Ray Zoo uvb setup is best I can add up for my needs...appears to have the spectrums covered as well as enough intensity for good production

Namaste'

Results

The EB Mega-Ray lamp is a PAR-38 reflector lamp with a moulded spreader lens on the surface and a slightly milky inner coating. Earlier models (2004-5) had short glass necks; newer lamps have a longer neck with a brass collar (Fig. 3.)

The EB lamp and ballast box are purchased as a kit; replacement lamps may then be purchased separately. At present these kits are only available in an 110volt version (the USA line voltage) and to operate them in the UK, with our 220-240volt mains electricity, we used a step-down transformer.

We found that some of the ceramic lamp fixtures we tried would not accommodate the bulbs with the brass collars, because the lamp would not screw far enough into the fitment. Bending the contacts within the fixture down towards the lamp solved this problem in most cases.

As with all externally ballasted mercury vapour lamps, when first switched on, the lamp produced a faint light from the arc tube which developed over a few minutes into a very bright light with (to the human eye) a purplish-blue tint and a directional beam.

The SB Mega-Ray lamp is almost identical in appearance except for the tungsten filament, which can be seen inside the lamp. A self-ballasted lamp, when first switched on it emitted a very bright yellow-white light from the tungsten filament which changed in tone to a bluer tint as the arc tube lit up and the beam developed.

The Mega-Ray Zoo EB Lamp is identical in appearance to the EB Mega-Ray lamp except that there is no milky coating on the inner surface of the lens; the glass appears completely clear.

1. Direct Readings

Because of the physical movement of the arc within the tube, and the way the radiation is generated, the meter readings from mercury vapour arc tubes are rarely steady at close range, and in fact the visible light can often be seen to "dance" as well, casting flickering shadows at the edge of the beam. For consistency, the highest reading seen three times at each distance is the one recorded, as it is assumed that this reading represents the most accurate alignment of the hand-held meter with the beam.

New lamps were “burned-in” for at least 90 hours before these recordings were made. All readings were taken after the lamps had been switched on for at least 30 - 60 mins, to ensure they were fully warmed up and the output stable.

(a) UVB recordings.

A series of direct readings were taken with the Solarmeter 6.2 UVB meter at increasing distances from directly beneath the centre of the lamp face. Figure 4 shows the output of all ten Mega-Ray lamps which were included in the trial.



The results show that these lamps do indeed emit UVB at the levels specified. There was wide variation between individual lamps; this has proven to be a feature of every brand of mercury vapour lamp we have tested so far. In this case, this was expected, since the lamps were labelled with their output as recorded prior to dispatch.

Readings at close range were higher than seen in nature, but at 18" (manufacturer’s recommended minimum distance) the four specially-requested "high-output" lamps produced levels of UVB resembling that found in natural sunlight – they emitted between 127 and 228 uW/cm² after burning-in.

At 12" (manufacturer’s recommended minimum distance) the four "standard-output" lamps produced similar levels, between 122 and 202 uW/cm². The "Mega-Ray Low" was emitting 71 uW/cm².

Figure 5 shows the output of the EB Mega-Ray Zoo Lamp after burning-in.



This lamp, designed for use only in very large enclosures, has a vastly higher UVB output. The recommended minimum basking distance is 36 inches; at this distance the output was 259 uW/cm². At 72" the lamp was still emitting 70 uW/cm². At all distances closer than 26", readings were higher than seen in nature even in the tropics.

(b) UV Index recordings.

In many countries, especially in the summer, the Solar UV Index is reported along with the weather forecast in newspapers, on TV and on the radio. The colour-coded Index is easily understood and is becoming widely recognised. To quote the World Health Organisation (from their online booklet, Global UVI ):-

The Global Solar UV Index (UVI) is a simple measure of the UV radiation level at the Earth’s surface and an indicator of the potential for skin damage. It serves as an important vehicle to raise public awareness and to alert people about the need to adopt protective measures when exposed to UV radiation.

**127 and 228 uW/cm² is sweet but im more on the 300+ thang

**just finished SC'n everything in site lolz, my fingers smell like dank tho

--cheers

(installed a UVc light in the main rez, all thats missing is oxygen )



**4:20am ..cheers

**found mites on only one Fn clone..THNX "berkeleypatientscare" bunch of tards.. LRN2GROW!!

<^>()

--places mite free (so far).. sr71 & HTC


..sweet, i get to play with predators.. lol

Hey wiz why you adding a uv light to your res?

**added the UVc for germicidal effect

..in love w/ this beat... happy TGIF

**since the mites were found (thnkkgod) before the switch to 12/12 we are just gonna excercise the right to run 2 back to back ( c02 cleanse)

--10,000ppm for 2hrs (3day interval)

/bye mites

Is that the same as a aquarium uv light?

**its actually the same UVc lights they use for the RO systems~

And by running it in your res your killing off batiria right?

**yessir, all the unwanteds that got past the membranes

Cool but what about the good bactiria that you want to keep
