other than HPS as in you cant afford an hps ? or you just dont wanna ?
you can flower with t5 flourescents ok but not as good as hps.
or you can flower with a bunch of compact flouros. not my favorite option but i will work if thats all you can afford. but just 1 wont do it you need a pile of them
It's not that, but the price of the ballast, but there are some ballasts for $26, but they are DIY and ive never wired anything in my life before. Any other options?
I'm afraid HPS really is the way to go, why not just get one of those vaporlight things everyones talking about? 150w hps for $20, with the ballast built in.
The only other options are cfls, which get pricey if you want enough to get anything like a decent yield, and are about half as efficient as HPS, or LEDs, which are expensive, and don't really provide enough light intensity for good yields.
