**** advice needed ****
In just under two weeks im headed back to London for 4 days so plants will be left alone. If i water them just before i go they should be good by the time i get back as they dont need feeding much more often at the moment, but my main concern is this:
Should i leave my tent open, or leave it closed? Night temps can drop to around 8 deg.C and day temps can peak around 23 deg usually. Im concerned that if i leave the tent open it will be way too cold for them at night, but if i leave it closed it will build up humidity in there and will not recieve any fresh air?
