Welcome back to journal week 5. Last week we briefly spoke about the recent growth shown in our rosemary plants. This weeks video focuses on the overall progression of our rosemary, ornamental purple pepper plants, and the introduction of some new plants in our growing environment.

Have a look at our video. Enjoy!


After weeks of our rosemary remaining somewhat dormant, we finally saw bushy growth in both the XML 350 and the 600w HPS. Although the size was slightly larger on the XML 350’s rosemary, the real surprise was how much more dense the plant was to it’s 600w HPS counterpart. We used a secondary lighting source to shine through the rosemary plant to gage how dense each plant was. The density of XML 350’s rosemary prevented most of the light from shining through. Subsequently, the 600w HPS allotted much more light to pass through.

From the previous week the XML 350 also showed much more growth in our ornamental purple pepper plants. In fact, the growth was so conclusive that we decided to remove them from both grow tents. The 600w HPS was producing inferior results across all 3 pepper plants, while the XML 350 continued to show new foliage and growth, deep purple tones, healthier fruiting, and an abundance of flowering from all three pepper plants. In the absence of these plants from each grow tent, we have introduced new patio tomato plants, cilantro, and black beauty eggplant to both grow tents.

The basil had very minimal growth, less than 2 inches in total, on both the XML 350 and the 600w HPS. Likewise, there was no yield from the basil at the end of week 5. Our total harvest this week is as follows: combined tomato weight of 178g for the XML 350 and 223g for the 600w HPS. This brings the overall total tomato weight to date to 1374g for the XML 350 and 761g for the 600w HPS.

With one tent housing our XML 350 and the other tent housing the 600w HPS, both tents are treated equally. For both tents we are using the same treatments, environmental factors, and water/nutrient blends. Maintaining equality throughout the entirety of the growth cycle provides us with accurate data and this data is used to give you true results when comparing an LED to an HPS.
