Hi - I have a small space (shower cubicle) not used 1.2m x 1.2m. I will line the inside walls with reflective mylar. I'm on a tight budget so I'm currently researching my options regarding led lighting. As you know this is the most expensive part. It seems possible to construct a LED light source with these LED cobs fairly easily so I'm wondering how many of these cobs will I need per plant if I have 1 or 2 plants in a small space like that. The cobs are full spectrum LED 50w from https://m.ligh
