Journal September 8, 2015 - Keeping the cost down
For this batch of Merlot and Red Salad Bowl lettuce I am simply using Expert Gardener plant food from Wal-Mart, where a 1.5 pound box will cost under five dollars.
Hydroponic nutrients are buffered the hydroponic dealers will tell you! Well, yeah, when I added a table spoon of nutrients to the tank, the pH was only 5.9, so I had to add a whopping 5 ml of pH up to bring it to 6.0. Big deal.
Once operating, there is no further involvement necessary, other than draining are replacing the nutrients every two weeks. Nice!
