Those Philips 6500K bulbs with a CRI of 85 will work great. $24.97 was a good price as they are usually $7 for a two pack. You need to keep them around 2" from the top of the plants. I built a pulley system to raise the fixtures which were suspended from sixteen inch chains that are used to raise the fixtures one inch at a time as the plants grow. The pulley system raises the fixture several feet for working with the plants and watering. |
