Hiya fellow tokers ...,

I have seen a few threads bout building yur own ballast about .. and none of them actually give u all the info u need .. I am thinkin bout building my own as i dont have enough money to buy 1 atm !! And my seedlings are already 11 days old . I have a 400 watt Sont- HPS its Mogul socket ... i also have a contactor which i made myself from yur DIY section. What i need to know is the specs for the Transformer, Ignitor and Capacitor .. i am on 240V mains !! Any ideas?
I found a site with some wiring diagrams for building yur own ballasts but no specs

Cheers

Unless you are a qualified electrician, then I wouldn't even consider opening a ballast, let alone building one mate.

They pack some big voltage and will give you no second chance if you do somthing wrong

Blatantly!

Those things have some big fuck off capacitors in them for the initial surge of power, and they are storing a hell of a lot more than 240 volts. It enough to kill you very dead.

They hold that charge for up to a couple of years after they were switched off as well.

You also have to consider what you are going to store it in. Plastic boxes will melt with a grow ballast inside it (I know this because my first HPS ballast was in a plastic ABS case).

By the time you get all the bits you need to do it safely, you might as well have bought one anyway.

that article is highly irresponsible...

Ok ok chill ppl i was only asking a question !!!!! Have a bong sit back and realx .. i will buy 1 from a lighting shop or summit ... !! I wont kill mtself for herb .... tho not far from !!!

Cheers

thank the lord for that! - seriously mate, they weren't pulling your plonker, ballasts are bloody dangerous things, many times more dangerous thatn the mains- and that can and does kill ! - they all yelled because its rather like seeing someone walking in front of a train - you're welcome here, its just we'd like to have you around for a while!

Believe!

aye and i dont know how many threads youve been told it in either
if you want to do, then do it... but repeatedly asking about it isnt gonna change the response you get on the forums m8

be safe man
