ok... cool... beer cups, 2 weeks ago...
depending on the size of the cup, the roots can take over in 2 weeks... actually, thats around my transplanting time, from small cups to bigger containers... i noticed if i didn't transplant in those 2 weeks, my plants started dying on me... because of the roots... it happened 1 time... i was like "what the fuck are you doing to me".... and i didn't get a response, ha... but seriously, i was going nuts thinking it might be nitro def... but it wasn't... my containers have clear bottom and i noticed the roots were piled up, fighting for space...
