CFL lamps near window - input please
No problems here. Just would like some input on my setup:
The weather has started to cool off and I have brought some of my herbs indoors. The picture below is my 'harvested to the root' chocolate mint (left) and spearmint (right). Lamps are CFL bulbs, 44W (150W equiv) apiece. One is around 6500k and the other 5000k, the latter will be replaced when I get to it.
The lamps seem to put out about 100000 lux at 1" and about 20000-50000 luxat half a foot as measured by my android. The sun through the window is around 180000 lux on a bright sunny day. I decided on putting the plants in the window so I could take advantage of this fact. Much of the day there is no direct sunlight, so the lights are necessary.
As you may have noticed the lamps are clamped on and bent at a certain angle and near the edge of the container. This is to allow the lamp light to hit all the plant whilst letting the sunlight also shine on it. The issue I can see here is that the plants foliage will be facing the lamp, and when the sun comes out and overpowers, the plants wont be facing the sun. If I were to have the lamps directly on the plants a way that would make the plants face the sun, then the lamp itself would block the sun from getting to the plants.
I'm thinking of putting a clear plastic bag over the containers to keep the moisture in but I'm thinking that wont really be necessary for mint plants.
The harvest was great and I'm hoping to be able to harvest in 2 months as this plant is said to produce a harvest every 6 weeks. I'm looking for any suggestions or advice you might have.
