I keep bonsai's and clones in a 1.5' x 1.5' x 1.5' box with just 20W of floros and flower in a 1' x 1' x 3' purpose built cab with 70W HPS..
No veg just straight from cloning into flowering cab..
Fed 1ml of B.Cuzz Bloom stimulator every other watering (every 4 days) / 400mls of water (each plant got 100mls every 2 days).. and gave them a shot of Canna PK 13/14 at 28 days and then flushed then with 1 Litre each of water mixed with black treacle everyday untill day 35???
