100watt hps on a 230v ballast?

ok im looking to do a steath grow... but im on a low budget.

I already have a 600 watt hps...

I was wondering if i could use a 100 watt hps bulb with the same ballast is this possible?

Thank you for your time...

Well it will fire but you run the risk of short term bulb life and the same for the ballast .you might try series a bunch more of the 100s to lower the impedance just a thought

what about a 150watt does the same rules apply?

yes you can. i run a 400wtt mh bulb in a 1000wtt hps ballast all the time. im not sure of the bulb life as i only run it for 60 days at a time. i have used this same bulb for 2 years now. when its done in the 1000wtt ballast it gets put back in the 400wtt ballast and up and running again.

Thanks for the comments...

Can anyone els confirm that a 100w hps will work in my ballast that i used for my 600w hps? I dont want to cause any fires e.g. Im looking to do a mini vertical grow in soil from seed. Will i need proper ventilation for a mini grow? In Mr Robinsons thread i read that if there is no shade above the lamp there is less heat so you can bring the plants much close to the plants and not worry about them burning. He used three virtical 600watt hps and got 32-40 oz off each plant lol. Here is a pic of my idea.

What do you think?
