started 2nd week of quarter recommended nutes. Using canna coco coir plus - so medium already buffered.
Coded an Arduino (nodeMCU) and temp / humidity sensor to send info to a dashboard i put together does this via wifi. This means i can check on temp and humidity without opening tent and check when im away from grow on my smart phone.
If anyone is interested in me putting a free guide together on how to do this - drop me a message and i will post one
