Im currently growing in a 2foot tall box with 3 26watt cfls in a basement.
My room is around 20 C° during the day but its canada and winter so my rooms gets cold at night.
Ive pretty much spent all my money so im trying to find a free way to heat up my box at night.
I tried putting a hot water bottle in next to my plants and it seemed to warm it up. However my box now stinks like rubber... could this be bad for my plant?

since it would be colder at night set your light schedule on at night off during the day
maybe a bit warmer during the day allowing you to leave the lights off and on at night to help
heat things up? perhaps?
