If you can hang your CFL horizontally, that'd be more ideal than vertical as far as the plant is concerned.
Tin foil isn't recommended as it creates hot spots.
Are you planning to have a fan to move air around? Doesn't need to be a big one in the space you have.
Generally when you find seeds in your MJ it's due to either a sneaky male the grower didn't notice or the plant hermied. Some people say this gives you fem seed but my first grow was bag seed and 7 out of 7 were hermies. No light leaks or anything that caused it other than shitty DNA in the seeds.
The wife has no issues with my hobby though she doesn't help out in the garden other than with money sometimes.
She enjoys smoking the end result as it helps with her Crohn's disease and comes to look at the plants quite frequently. It's our thing and we don't talk about it with anyone we know...
Here is my current feed schedule. It's a work in progress and I tweak it a little every grow.
CE= Canadian Express
DM= Dutch Master
HG= House & Garden

Your buddy is correct. Put an ounce of stinky buds in the tent and test the outflowing air with your nose again.
Was your filter sealed inside a bag when you received it? It should have been so it doesn't absorb moisture etc while it's sitting around in the warehouse.
Once the plant gets pollinated, it pretty much stops producing the chemicals that we want it for and puts all of it's energy into producing the next generation.
Personally, I'd start over.
