Part II - Flowering
Now that I have the layout pretty much worked out, I turned my attention to the flowering room. This past year, I have experimented with a couple of different methods of growing, but still prefer the no-till bed. I really enjoy the process of feeding my plants by hand, it allows me to spend some time observing the plant for issues. Spending time with my plants is very therapeutic for me. Back when I was thinking of doing a 4' x 4' room, I knew I wanted to do a living soil, but I was torn between doing four 25-gallon pots or one 100-gallon pot.
Workshop - version 1.7.1 - four 25-gallon pots
Workshop - version 1.7.2 - one 100-gallon pots
Once I settled on the 4' x 6' room, I realized this is basically three 2' x 4' areas combined, This is roughly the same size as my no-till cabinet, so I decided on three no-till beds on castors. This way, I can easily move the beds for maintenance and cleanup. This setup would also allow me to run perpetually if I wanted to, but I have preferred to run full cycles in the past. The plan for the bed is to have a base made of wood and covered in pond liner. This will then have a custom made 30-gallon fabric bed that fits inside the base, just like I made for my previous cab. The base will allow the bed to be moved as well as catching any runoff that may occur.

With the soil beds all figured out, I turned my attention to the lighting. I was debating building a ChilLED light kit or getting a Fluence SPYDRx. The issue is, these are both designed for a square area like a 5' x 5'. So, I started taking inventory of what I currently have. I already have two identical lights for my workbench, and the parts to build a third. The only thing I'm missing is an extra HLG-240H-24B driver. I decided that, since I wouldn't have to pay for a whole new light rig, I would experiment with some supplemental lighting. I decided to run two Emerson boards, and two Exotic Spectrum boards from Rapid LED.

The following illustration shows the light and the different spectrum I have available. The layout is such that each bed will have a ladder style light over it and the supplemental spectrum boards on the side. Starting with the rack, each rack has six 2700K SolStrips (yellow) for flowering and three 5000K Solstips (blue) for veg running at at 40W each. The supplemental spectrum boards each run about 30W and both have two channels that can be independently controlled with a PWM controller. The Emerson board (red) has a combination of Photo Red (650-670nm) and Far Red (720-740). The Exotic Specturm board (purple) has a combination of UVA (390-400nm) and Infrared (840-870nm). With these, and my Bluefish LED controller, I will be able to dim each channel of lights independently. This will allow me to do things such as adding far red before lights on and lights off, simulating sunrise/sunset, and changing spectrum and intensity for flowering and veg. Each of these channels (represented by a different color) will also be able to be turned on and off independently using a Sonoff wireless timer.

Exhaust is still a work in progress, but the plan is for a ACInfinity Cloudline T8 with carbon filter and a couple oscillating fans for circulation. This will be covered in more detail later along with electrical.
