I was wondering something about flushing. Does it matter what you use to flush your plants? I have a sink downstairs and I want to use that when I flush my plants because I don't want to bring them upstairs to the tub. Does it matter if the water is hot or cold? And how do I know when to stop giving them water lol?

Also I want to see what topping can do..On my next grow I might try LSTing my plant and then topping to see what happens lol. I wonder how many tops I'll get. When should I top my plants? Like how many nodes should they have?
