Original rack looked exactly like that metal one was modified to hold double the width by joining two trays together at the top and bottom, and removed all middle trays, Also designed a wooden short table/chair like thingie as a base to support and lift the bottom of the structure!
Wooded Chassis for the doors that was installed on the front of the modified rack, Later it was covered in MDF (compressed carton layers).
Cupboard's side - exhaust fan.

Self Sustained Grow Area Setup: Elevated 2-Door Cupboard Style (L90cm x W80cm x H160cm):
😍😍 [100% D.I.Y. Project] 😍😍
=====================
The Idea was to build a micro grow space that requires minimum maintenance and still have controllable environment and reasonable project cost.
Note: Average Temperature where I Live is 28-32 °C.
=====================
Interior:
=====================
Reflective Film - Glued on the surface - 360.
1x 400W Metal Halid Lamp - About 130cm from soil surface - Top Center. 18hrs schedule.
2x Neon 40W (Fluorescent) Lamps - Middle sideways. 18hrs schedule.
2x Main 20cm outlet fans + Dual interior chimney - Top sideways. 20hrs schedule.
4x Small air-circulation fans - Middle Cross-sectioned. 24hrs schedule.
2x medium inlet fans + 2x active carbon dust/smell filters - Bottom Front. 24hrs schedule.
1x 50Liters Wooden Bucket. + 1x Soil Multi-Meter (Temperature/P.H./Light) - Centered.
=====================
Soil & Irrigation:
=====================
14L Team Agronomist Organic soil mix
1/3 Brick of Coco-Coir free of bacterial and fungal spores, low in natural salts + 20L of Water (5.5P.H. + 50gm 19-19-19NPK) - Rinse for 1h then drained and mixed with organic soil mix (which contains perlite).
Self Irrigation: gravity based system of 2x small clay water containers buried in the soil with attached tubes to a 20L reservoir placed on top of the set-up.
=====================
Chassis & Exterior:
=====================
Chassis: Modified Metal Rack.
Walls: MDF - Compressed Carton
Doors: Wooden Chassis - Covered in MDF
Attached to one Door: 1x Temperature/Hygrometer/Clock with additional wired sensor attached to the middle of the grow space interior.
=====================
On Top of the Racks (Exterior):
=====================
1x 20L Water Reservoir (20L Mineral Water + 20gm 19-19-19NPK).
Igniter + Ballast for the Metal Halid Lamp
1x Programmable 3-slots electric power surge (control unit).
Wires, Switches, Surges, Fuses, ...etc,
=====================
Program for 3in1 Control Unit:
=====================
Chanel (plug) 1: dedicated to circulation and inlet fans - always on.
Chanel (plug) 2: dedicated to main halid lamp and both fluorescent lamps - 18h on / 6h off schedule for all week days.
Chanel (plug) 3: dedicated to both outlets only, 20h on / 4h off schedule for all week days so that it turns on/off 1 hour before the lights to guarantee that the grow space does not get hot.
=====================
Set-up Cost - Excluding Seeds was around: $600; and a lot of effort and dedication (about 250 hours).
