Back in February, we started our experiment to test how Heavy 16 fertilizers and APTUS additives performed compared to General Hydroponics’ Flora Duo. We have been growing Trinidad Scorpion peppers using separate drip to waste reservoirs, feeding individual plants in the same 4′ x 4′ Botanicare grow tray. All of the plants are being lit by a single 400 watt High Pressure Sodium Hortilux SUPER HPS bulb. As a refresher, check out Update #1 and Update #2. After a little more than 3 months, we have had to end the experiment a bit early. While both fertilizers performed admirably, the experiment was hijacked by a massive number of aphids.
Due to the fact that the aphids could not be controlled by organic pesticides, I have decided to end the experiment so as not to bias the results. The final results have been tallied, and the total fresh plant weight (weighing the stems, leaves, and flowers) is shown below. Thank you to all who voted for this experiment as well as those who have been following it diligently. If you have other experiments you would like to see performed, please email me at email@example.com.
