ya, to water I use a rainmaker 2 gallon pump sprayer with the spray tip removed. It allows me to give gallons through a wand without ever needing to move anything and even measure exactly how much water/nutes I want to give to each plant. To flush however, I have a very large 10 gal stainless steel pot that I place under each plant and collect all the run off to measure PH ect. I would urge against leaving it in the tent to evaporate. This is very difficult to do with the Scrog intact and is the main reason it keeps getting removed. As for crop King seeds...I have 8-9 strains but this is my first ever grow so only have experience with the White widow. I had been told early on to only grow 1 strain the first time so I know if it's a bad seed ect. I hope this answers your questions.
