I've pushed up to a dozen plants with one 400 watt hps and harvested over a lb. It's enough light for a sq meter of 3' x 3' space.
I've also supplemented with florescent side lighting (4) 4' T5HO).
Recently I'm running (2) 400 watt MH/HPS with the side lighting. I've got 14 plants finishing up soon (in Week 11 Bloom cycle)
Eight of them are AK-47, mostly sativa dominant.

Best of luck, looking decent!
Shovelhandle Reviewed by Shovelhandle on . AK48 grow log :rasta: I started this grow 2 months ago...sorry for not starting from the beginning. So here is what you missed since my first grow... I ordered my seeds from Nirvana again and this time I got 5 feminized AK48 seeds. I have read nothing but good things about this strain and I wanted to try it. I recieved 10 freebies (unknown strain) with my order. When I got the seeds I threw them in a glass of water for 2 days until the seeds germinated. (I love this method btw) Its easy and idiot proof.
