My 1st grow - 4 Auto RQS Greenhouse

As stated it’s strain dependent. Low temps will most likely stunt your plant or limit its growth. I’ve had outdoor plants withstand 2 C nighttime temps for 2 weeks. That being said if you don’t want to add a heater to your little greenhouse at night you could try and get your hands on some bricks. Bricks act as a thermal mass and if you place some in your greenhouse they can absorb the heat from the sun during the day and slowly release the; heat back during the night.

That is what most people do. Soap and neem oil and spray heavily you can also use pink himalayan salt diluted with water, this will kill the bugs but not harm the plant, normal salt will harm the plant 🌱👍
