I've planted 2 x Raspberry Cough and 1 x White Widow feminised seeds and have them in my greenhouse in north west England. I have grown these before and get good results in my greenhouse. I planted 1st week of June.
They are in an organic super soil mix in 46 litre tomato Grow Bags from Wilkinson's. They get just the right size in my greenhouse with a hefty amount of LST, Topping, Fiming and Defoliation.
During flower I'll introduce a dehumidifier to help against bud rot and will get at least 2 x treatments of predator mites as a preventative measure against red spider mites.
The plants will be given more space in the greenhouse as they need it and will only be given the occasional molasses tea during flower.
I'll expect to get 10 to 12 oz total from these 3 plant of nice final product which will last me through the year.
Picture below as of yesterday, the White Widow is in the middle. I'll add more pictures as they mature...
