When the time comes I just pull them up out of the containers and move them into the flower room.

I have 2 - 1000W HPS for a total output of 290,000 lumens. My lights have vented hoods the take the air from one room and vents into the attic. That way my room is totally sealed to keep the CO2 in the room. I use a 440 CFM fan to vent my lights. Lights are run at night to help keep temps down.

I use an A/C unit during the heat of the Summer but don't need it the rest of the year.

I use a complete greenhouse control system with CO2. I keep my CO2 at 1500 PPM during the day cycle.

I keep my humidity below 60% and have a 200 CFM fan that vents into the attic to keep humidity in check.

I'm running 3 separate Aero/NFT systems so I can have 9 weeks flower time and a 3 week perpetual harvest cycle.

I use a cycle timer for the pumps. The timer is set to 1 minute on and 5 minutes off. This allows maximum Oxygen to the roots without letting them dry out.

I made 3 separate Aero/NFT systems using PVC fence posts. The plumbing runs inside and is made from the same 1/2" PVC pipe I use for the cloner. EZ-Clone sprayers between each plant site.

14 plant sites. 396 GPH pump.

The frame is made from 3/4" PVC pipe. 18gal. Rubbermaid container for the reservoir.

Here is my formula for my flower room:

Botanicare Nutrients:
126ml Cal-Mag Plus
150ml Sweet
180ml Liquid Karma
540mlL Pure Bend Pro Bloom

I run 2000 PPM all the way until the flush cycle. Some strains like AK47 can handle over 3000 PPM without burning. Other strains show signs of tip burn at just 1700 PPM. Since I run 10 different strains I set my PPM for a good overall value.

Check out the photos for details on my flower system.

Flushing and harvest next...
