I was trying to grow some herbs under cheep Epistar Red/Blue light and a white 3000k light
On left Low efficiency total 10 watts 6 Epistar (2 Red and 4 Blue aka Purple monsters)
On Right is Philips High efficiency 140Lumen/Watt L235-3080AHLCBBAC0 Warm White, 3000K 1500 lumens @ 10watts
On Apogee PAR meter Philips Strip on Right is about 30% more powerful than the left.
Same soil and watering schedule. Added a few more herb cups on 4th day. I was not able to water them for last 10 days due to some personal emergency. I plan to taste the peppermint from blue/red and white3000k after 2-3 days.
Setup
Day 1 Day 21
I have attached a time lapse video of 21 days. Sorry could not upload video anonymously so I had to put it in a zip file. An old phone with IP Webcamera app to remotely take pics once everyday.
I was expecting to see some good growth on right but results do not make sense to me.
1) Right has more 30% PAR and is white.
Why these herbs are leaning towards the Left Red/Blue...?
2) There are 2 big peppermints. The one of left seems to be growing faster. Overall growth on left seems comparable to right if not better with exception of far right Parsley.
3) There are 5 cups on front. Middle and far left and far right are Parsley. Although far right Parsley seems to have best growth out of the 3 Parsley seedlings, 3000K has stretched far right Parsley seedlings to death. I think 4000K would have worked better
Any idea what is going on. Why are they leaning left.
Edit: out of the 6 Epistar @ 10 watts, 2 are Red and 4 are Blue
