1. It's genetics, you can't control whether the high is a creeper or not.

2. To make your buds harsher, dry them faster (I don't understand why someone would want harsh smoke).

3. It really depends on what type of reflector you have. If you took of the reflectors, the light would be able to expand further, thus allowing more plants to be grown. I can't really caculate exactly, depends on how large you plan to grow your plants also, I'd say using both, over fourty small plants, without the reflectors.

4. The stripes are due to the fact that the seeds are fully ripe. The stripes do not determine the strain at all.
