Well if ure from around here then you know that one day we can have a cloudless sunny day with heat blazing to 25 degrees celcius. and then the next will be an ugly dark rainy cold day. anyways my babies are on the balcony working off sunlight but sometimes well have a week of absolutely no sun. (like this week) Should i get lights for when this happens? or is this natural considering outdoor plants would go through this anyways?
