Hi dudes! Well so its time for me to shop for a ballast and light and its also time for me to break with most of the tenant agreement rules. I cant keep fire hazards inside my apartment. I dont mean to say that ballasts or lights just catches fire, its only Ive read about the horrid marijuana fires on the internets and I am trying to make sure this never happens. Well so I am lookinjg at this ballast: http://www.hydrogarden.se/ljus/ballaster/maxibright-digilight-digital-ballast-250-watt.html Basically it says that this ballast is digital, which is good It also says it has "low heat development" Its a 250 Watter. Now I have plans of using a 250 W bulb or 400 watt I have not yet decided really. I have some questions 1. Can the ballast catch fire? I have plastic mats in my living room, where the tent will stand and plastic can burn (and baad) Where should I place the ballast and on what? 2. Will the light explode? I have heard stories of these lights popping. Aside from going blind from shrapnel, its the same fear: FIRE... Are there any rules or guidelines I should follow? I know to clean the damn bulb, but other than that nothing- So basically I want to prevent the risk of fire and keep safe. Oh.. 3. I am looking at both magnetic and digital ballasts. Whats the pro/con in safety terms. I am ready to go with a magnetic one, theyre way cheaper and I can use 400 Watts instead of just 250. Whats the difference, is it safer to go digital?
