Alright so let's start from the basics we use nutrients maxigro powder premix in a solution and then dumped into the bigger Reservoir. Then it goes into our blocks which are pH 5.5 then go up to 5.8 the pH never goes / 6.1 we water according to the growth rate of the plant so I would say watering cycle start at 1 times a day for 45 minutes approximately an inch and a half deep across the tray. They do get added CO2 to the room of upwards of 1,200 ppm's but only for 4 hours a day out of the 16-hour light cycle we do add Cal Mag plus but it comes from raw. Temperature in the room is anywhere between 67 at night time and 76 during the day humidity levels are 55% to 40% the reservoirs food stays at 1200 ppm's and then goes no lower than 750 and that would be a time of a Rez change. The lights that are used are LED lights there is three over each tray so they're getting approximately 3000 Watts worth of lumens the ppfd is roughly around 1000
