I'm pretty disabled and this is my first grow I have four plants from Northern lights Nirvana shop 600w 4x4 tent. Obviously I've learned a hell of a lot because just like everything else in my life I tackle it 110% and I am pretty much overwhelmed at times but one of the big things is reservoir changes as you all may know. I've tried hundred dollar water transfer pumps, I tried to cheapo's, I tried just about everything and I came across this little guy I seen before but this time I snatched it and it really made a big difference for me.
