So just doing some comparison, What light/size of space/ yield of your 1st harvest? Pix if you get them too is more then encouraged!
i used 2x600w hps and had 30 plants in a XXL tent... got 1.2 kilograms dry... i used co2 injection too was pretty happy with the result.
i used feminized white label power plant seeds and some fem. blueberries... i ran veg for around 5 weeks
