Chappie is that all the information about what you have available to you. I will write up a plan for you that will increase your yield and the quality too using the same space. I understand you do not want to spend lots of money but some time there is no choice for max yield. Save the information and implement it over time. I think I remember you are in the UK right? So I have a better idea of what is available in your market area. I have mentored over 50 medical users in my area on growing indoors in the last 2 years alone. They are all growing great crops and often share their pride with me to show off their skills. Give me a few days and you will have something to read. I am happy to help you and anyone else they may benefit
