newbie here, thinkin bout doin some growin! I've been growing houseplants and gardening forever. And of course i like to smoke,,,, so here i am! Lookin to possibly just start out small,, just for a lil personal use. Lookin to start out with just one plant at a time. Will a 70 or a 150 watt hps work well enough for a single small plant? I'm not interested too much in spending a ton of money until i know for sure i want to be doin this, and these size lights I can come by easily enough. Any help is appreciated. thanks!
