If you were to grow a lowryder then yes it would give quite a decent yield but only on lowryder.. I once grew a lowryder in an emptied out pc case with the inside painted in matt white with just one daylight 30w spiral cfl bulb and it was 17inch tall and the resin production was very high.. when dried and cured I got 42g and made 17g of hash and was very potent and tasty too..
