Wow you have some good plants there. Now as a new grower just like your self i'm going to give you info on what i'm going off of. I may be wrong but i'm sure some of these growers on here will correct me.

1) I heard that you can Re-Vegged a plant 2 times since it puts a lot of stress on the plant. So after you harvest then you may want to leave some leafs and a few buds on the plant since the new growth will come out of the the buds that you still have on there.

2) from what i have been told you want to look at the hairs on your bud... when it turns a little dark but still fresh then thats is when you want to harvest. There are many tips on harvesting on here so check them out.

3) your outlet needs to be fix ASAP to in sure that your plants get the light it needs and no power shortage. If you can go out and buy a long cord from your downstairs to your upstairs and when the guy comes to fix it next week then go and return the cord so make sure you save everything it comes with.

4) now to clone you may want to cut leafs from the top since they are older they will grow better with that strong age it has.

5) The smell from the filter i'm not sure about. I'm sure everything with that should be fine since many people do use it and havnt said no to anyone who wanted to use it. I jus keep my fan going and my window open since i only have 2 plants. For me it doesnt seem that i need to get a filter since my 2 plants are buy the window and the fan does keep air flowing all over my room...

i hope some of my things that i told you helps you out. but keep us updated so we know whats going on and keep them pics coming.... good luck....look on youtube for a movie called...STONED GUIDE... tells you everything that you need to know about growing...
