Here is the thing if you want to maximize your harvest you need to cover ever inch under the light. Weather its 1 or 5 or 10 girls. You can't waste an inch of available light.Pretty patient experience, and yh I have small bud on heater on a spoon yeo happy friday 420
Then your light . I don't know what you have available where you are. But there are alot of sponsors that will do their best to get a light to you.
For same amount of euros in electricity you will improve everything about your girls.
I can recommend some economical options if you like.
If you are going to spend 4 months doing something you should be pulling 4 months worth of smoke minimum. If your not then its time to up your game.
I hope your harvest is fantastic smoke and your thrilled.
Just something to think about my friend.
