Maybe I'm the only one not omniscient, but since you never stated what size bottles you used, I don't know how anyone can say what the outcome will be.
Since someone may read this thread later that isn't as expert, I thought I should add this clarification:
For 12 ounces bottles, if you used 1/2 tsp of sugar they'll likely be perfect. I assume that's what you meant by "pop the tops", using 12 oz bottles with metal caps.
For 1/2 liter bottles, they'll be ok, perhaps a little under carbed.
For the 1 liter PET bottles, if you used 1/2 tsp of sugar then they'll be flat.
As stated prior, doesn't matter what you brewed with (booster, LME, or just the HME), the carbing comes from what you put in the bottle with the beer.
