@g_slim, thank you very much :). I thought about setting up a sun reflector and I will propably set one up for future grows. But I think I will not set up a lamp just yet, at least not until autumn... To be honest everytime it is cloudy or rainy (which is quite often) I am worried about my grow. But I also think if I start using lamps I will open up a bottomless bottle and will start to optimize everything and end up using an expensive set up... At least for now I try to keep it as minimalistic and practical as possible :). And I am quite happy how it turned out just the way it is. But thank you very much for the ideas and eventually I will propably upgrade the set up... In the latest when winter is coming and I am out of weed ;).
