I have big interest in growing 30 lowrider plants under a 1000w HPS. This would not require me to use the MH bulb, and in 50-65 days, I'd have an average harvest of 900gr dried (feminized plants). Is this a decent harvest (2lb) for the time the light is running (2 months)? I would rather harvest frequently rather than wait for a bigger harvest (using regular plants with MH and HPS)
