I have tight space, no more space for also reflector, that is reason I was interested in solacure Your info would be precious in case I can upgrade my tent for a larger space (4x4)

230v is a standard also in Spain, France, Germany and almost every other European countries

Anyway, thanks for your reply and help

Already tried to ask them, but no answer yet Anyway, your ballast should be an electronic ballast with no require of starter Still trying to find a t12 socket (just t5 or t8) and a compatible ballast

I would like to know more detail about mounting/assembling, if possible In your part list you used 1 ballast for each uv lamp, but your ballast is for 120v input. Any suggestions for a 220-230v input? No need for starter? Is pissopos to dim uv from that ballast?I am in a 3x3 tent and would like...

@Bigfries Have you started using uv? Are you driving each bulb @18w ?it is suggested a distance from canopy of 3ft, if driving at 18w

2 questions: -Only dirt grower can make 1 hole for draining/flushing? -if I start competition in 1 small box than move party cup in other larger tent, it would be ok? (Since I must go 12/12 from seed,I would move party cup only when my tent is ready for flowering )

Hi everyone, I am planning on add some Uva to my led fixture, but I do not know how many watt/m^2 I need. My plan is to keep Uva on during light on with for 6/8 hr or for 12hr.Can someone tell me how strong Uva has to be?

5 or 6 project 342 board will run passive at 100-120watt each,no heatsink BTW....600 watt of this light will be enough for a 5x5 tent (150cmx150cm)

Wrong math. Zeus 308 x 4=279.60 At this price you will get 308 watt of light,passive cooling. 4 projects 342 are 517watt of light with no need for heatsink If you want more than 80 watt from Zeus 308, add heatsink cost. I prefer a board that cost 10€ more, with better coverage (twice the...

Gen 6 1212 at 50watts should be around 2.15mmol/W so if you are using 5 of them ,250 W of light will be: 250×2.15=537.5 ppf 537.5/0.81 (surface area of your tent, in m^2)=663.5ppfd Consider reflectivity loss (-10%)=597ppfd So, your ppfd should be around 600 but if your light does not evenly...

Nobody can flower 1000watt in a 3x4(or just few members here).Maybe a 600watt hid that will have a lower part output.And you can have same or better ppfd from 300watt of that configuration.Or use 400watt and be near a gavita 750watt de

http://www.flowerpowerbologna.it/epages/99883.mobile/it_IT/?ObjectPath=/Shops/99883/Products/6000&Locale=it_IT Here is a grid with reading from a 90x120(3'x4')tent using a 4 board setup,515watt from plug.So using half wattage to replace 1000watt SE is possible,and you will have even better...

I would not. 240watt from a 2 cob fixture will have much lower efficiency and can not compete with uniformity from a 2 board fixture Last thing....a 4 board fixture using 515watt will have a better watt/€ price,comparing to spectrolight and will destroy it both on efficiency and uniformity

Tent is 120x90 cm(4ft x 3ft).Is the same tent used for taking ppfd reading already posted.

I took it as personal and asked vendor for a quick video with ppfd reading. Now everybody can see data are real and not bull**it Reading taken on the outer perimeter of the tent and also other random points, but ppfd numbers are almost identical to what they have already posted

Well, there are picture of original Samsung packing with bin on it.It should be a good sign of original board.

Well...I am not vendor so I test it for myself (of course I wanted to test if vendor was right about what he was claiming :bigjoint: ). HLG do not post any test for over 1 year but people trust them about their ppfd reading. Maybe you can ask vendor some picture, but I do not feel comfortable...

I can confirm ppfd reading for single board test since I have done that test using apogee sq-520 borrowed from vendor. I was at his shop yesterday, while he was taking measurement, so I have seen it for a while ( just test with fixture at 18 inch, than I had to leave). I also shared some picture...
