So, Ive got my share of experience in killing plants and was wondering what mistakes you have all had, might help others prevent doing the same.
The first time i grew few years ago i used ONE regular bulb, they stretched and i had no idea why it was falling over.

Then I grew it outside and after a few weeks and great growth they were eaten by bugs even though i put up fly nets. Im not sure what i could have done to prevent this but just to let you all know that that dangers still out there.

Now Im growing inside in a box with 3 23 watt CFLs and for one night i only left a little hole in the box for air. The coputer fan i had left running placed inside the box and the next morning one of the smaller plants has dried out from apparently over heating. So, ventilation = very important.
