Hi folks and to my 3rd medical grow using Autoflowers. I'll be using a DIY ebb and flow system that was relatively cheap to setup, is automated, & runs from my phone. The environment consists of an insulated grow cabinet that measures 5 feet height, 4 feet in width, and 3 feet in depth. The cabinet is an odd size as it was built to fit an odd space. There is no visible hinges or locks on it, and must be opened via a remote control key fob. And yes, I mounted a 46 inch TV to the door of my cabinet....cause well, why not?
For this grow I'll be using Mega Crop, GH liquid koolbloom, GH CaMg+ if needed, and H202 for sterilization. Cyco PH up/down, and I think that should be it.
Lighting will be a vivosun 400watt MH/HPS.
Temperature is controlled via an Inkbird Wi-Fi controller (can adjust by phone remotely). There is an 8 inch exhaust that eventually gets reduced down to 4 inches. And a 6 inch intake reduced to 4 inches. Air is exchanged via tubes to outside.
Humidity will be controlled by Inkbird humidity controller operating a mini humidifier and dehumidifier (swapped in & out as needed).
A 64 liter tote will act as my reservoir. Sitting directly above it on a DIY stand is two cheap mortar tubs fitted with ebb and flow kits from the Zon. A cheap vivosun water pump acts to flood the mortar tubs with nutrients. Watering is on a cycle that runs for 1 hour floods every 3 hours, this can be overrode anytime by phone for a manual triggered flood. Inside each tub and the reservoir is airstones powered by a cheap vivosun air pump.
On top of each mortar tub is DIY covers made from plywood holding 4x 6 inch Net cups.
Of course I have tds and PH pens to adjust the nutrients (aka nutes). Target PH will be between 5.8 to 6.5 using natural PH drift.
Here is a pic as I'm resetting the cabinet from my last run.
The intake air ducting wraps around the reservoir helping to chill it. There is also a water leak detector on the floor of the cabinet.
The cabinet can also be monitored remotely via a paning camera.
Here is a write up on how I automated my grow. You can read the pros and cons.
How to setup a smart power strip for a grow
This grow will have light defoliation as needed, lots of LST, supercropping, and a scrog net to help. I've used all in the past grows without issues yet.
Beans have been dropped in water. More updates shortly!
