so you think a 1000 will cover 6 ft each way with a 4 plant scrog setup?mr2shim has it right. Depending on the size of your tent, you may only need one plant. My tent is only 3 x 3 and it's def going to fill up. If you were going 4 x 4, two plants might be called for. It's probably worth noting that light is the main limiting factor here. If you're growing under a 400, one plant should be great, 600, go for two, 1,000, step up to four. This is all assuming you're using a scrog to maximize on light exposure.
