Hi - I'm a newbie to this. This is only my second grow and the first last year was entirely outdoors with plants started from bag seed. They grew and flowered awesome, however the THC content was very disappointing. So this year we decided to try two mixed indica/sativa strains, White Russian and Bubblegum. So far they are doing great outdoors growing in large pails but we will need to finish them indoors as we start to have frosts here in early September and they won't be ready until mid-October. My question is, what will I need for lights for eighteen plants? I'm on a budget of course and also live in a fairly remote area so I need something I can access easily and quickly here or online. The space we will have them in is about 15'x10' approx. I appreciate any advice you can offer. Thank you.
