1. Brita water filter Yes or no 2. my plant came in a pot that has no hole at the bottom is top feeding ok or should i change the pot?
and i quick question about dormancy, rite now it is -10 C out side i noe i have to keep the plant between 0 and 10 how can i do this My garage is the same temp as out side and get no sun. it can get down to -22c out side where should i put my plant!??
Brita water filters take out some of the dissolved solids, but not enough to make water acceptable for carnivorous plants. The only kind of filter that does that is a reverse osmosis unit.
It's fine to water it from the top, but you have to be very careful with a pot that doesn't have drainage holes in the bottom. It would be very easy to over water your plant and give it root rot. I would transplant it in the spring time to a plastic pot with drainage holes.
If you can't find a good place to put your plant for dormancy, you could just try a cool windowsill. Do you have any windows that are drafty and stay cool?
