the ones your friends are talking about at walmart are not HID and if they are they are shop lights and wont grow your pot very well. IMO the 400w hps or 400w MH setup is your best bet. It probably wont be enough to grow 20 plants at the same time though!! you could probably do 10. I grew 8 under my 400w MH setup but that was because i couldnt fit anymore in my space. check my grow journal to see pictures of them now. on 12 days flowering. anyways, its worth it if you plan to continue to grow and want high yeild of your plants. also get some good nutes. like technaflora, advanced nutrients or fox farm nutes for bigger denser buds
