@ILGM.Zoe this is directly from ILGM:
"This type of marijuana does best indoors. For this kush to flourish well, use a hydroponic setup. Since banana kush grows to a medium height generally, it is easily manageable in small spaces provided the grower keeps on pruning and training the plants.
It is also essential to ensure that you have enough airflow for your plant. This means ventilate your grow room well! Banana Kush likes it warm. Keep the temperature conditions between 68 and 80 degrees Fahrenheit.
When grown indoors, this cannabis takes approximately 8-9 weeks for the plant to flower up. It has a yield of moderate to high, with the average being about 18 ounces of usable marijuana per square meter.
If you live in a warm enough climate or have a greenhouse, you could grow this strain outdoors. Growing Banana Kush outsides will yield you about 21 ounces of usable cannabis per plant. Your crop should be ready for harvesting in early October.
During the flowering period, keep the humidity down to about 40%. It is moderately difficult to grow this strain, but most should have no trouble with it. However, make sure to keep plenty of nutrients on hand, in case you do"
