I want to do a small setup.

What are ballasts exactly and do i need them to do a cfl grow? should i just get a bulb and a socket and plug it in the wall socket or do i need the ballast for a cfl light.

What light spectrum do i need for veg + flowering. 6500k?? i got lumens covered.

For the filter i will use a diy carbon filter. How often does it need to be replaced?

Since i dont want to plant to be too tall. do i do a 20/4 light cycle until its my desired height and then quickly switch to 12/12 or gradually switch down by 2 hours every 2 days until 12/12.

thanks
