I just use a famur tf1200 it's around $80-100 depending on sales and people have been getting around 110-120 grams on a 110 watt light is what I've read on reviews. (Good for 1 plant).
An 1/8 is only 3.5 grams so you can do the math. If you just get 1/8 or 1/4 it's not really worth your time.
I picked up bottom of the bag bud of GDP for $8 plus tax for 1/8. I'm sure your seeds cost more than $8 and also all your time as well.
Just get a budget led light and your plant will just start to explode.
