600w HPS vs XML 350 LED – Journal Week 6
Welcome back to journal week 6. You may recall in the previous week we removed our ornamental purple pepper plants and added a few new plants to each grow tent. This weeks video shows dramatic growth across all the plants in each grow tent.
Have a look at our video. Enjoy!
The black beauty eggplant took off on both the XML 350 and the 600w HPS grow environments. However, while they both showed a fair bit of growth, the XML 350 grew slightly larger in size than the 600w HPS. The most noticeable of changes this week was the cilantro which was denser and overall wider using the XML 350 versus the 600w HPS. The 600w HPS grew the same height, but was lacking in the actual production of harvestable cilantro. We will keep a close eye on the cilantro to see if we have even more growth in the upcoming week, or if the 600w HPS is able to catch up. To wrap up the progression of the newer plants from week 5-6, we also took side by side photos of our new tomato plants. Both of the new tomato plants grew taller with new fruiting on both the
XML 350 and 600w HPS.
Looking at the older plants from the beginning weeks, the basil grew about 1 inch taller on the XML 350 side. The XML 350 also showed more growth at the bottom of the basil plant than the 600w HPS. While the 600w HPS did not grow as tall as the XML 350, it performed very well with basil leaves growing larger than the XML 350. As for
the rosemary, the XML 350 is still out performing the 600w HPS across the board in weight, density, and size.
Our total harvest this week is as follows: total tomato weight of 111g for the XML 350 and 60g for the 600w HPS. This brings the overall total tomato weight to date to 1458g for the XML 350 and 821g for the 600w HPS. Once again, there was no yield from the basil at the end of week 6, maintaining the same total basil weight of 195g for the XML 350 and 180g 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.
