New Grower Good at day but below 10c at night, What to do?

[mcm94]

As someone said above for the temp, use a kind of cardboard box, and if possible, insert water filled plastic bags (sealed) or a black tape covered 2L bottle around the plant, this will capture the heat during the day, and will slowly release during night time, roots shouldnt go under 13-12c with this prep
Ive tried it before and works great, just add a small amount of bleach to the water to ensure that after days it wont mold or grow bacteria/fungii
good luck
