1. yeh, pruning can be done.. search on LST and Topping...

2. your plants will flower in the autumn.. but i guess you could restrict hours...

3. preflowers could show at any time, but usually towards the autumn.. (balls = male, hairs = female...)

4. noo.. but sounds good

ur in the uk like me.. so use a ring of broken glass to repel slugs.. boil out any ants nests before you plant.. AND FIND A GOOD SPOT WITH LOW HUMIDITY.. good luck m8y
