Not even close. 40ish watts of leds is the minimum I would go with. Sansi has lots of cheap options
Nope. These plants need to be outdoors. Besides the huge lack of light, they need to go into winter dormancy.
How many watts? It looks like less than 10w. They need a lot of light
Most of the technical information you’ve copied and pasted is completely irrelevant.
This is a common problem when people shop for grow lights online, because consumers are used to statistics that describe how lights look to human eyes. What you care about is **PAR**, **PPF**, or **PPFD**.
**PAR/PPF** = the amount of useful plant light that the bulb emits. This is a single number.
**PPFD** = the amount of useful light that actually hits your plant, based on distance and angle. This could be a chart, or it could be a single number combined with a distance (for a plant directly under the light.)
Ideally, you buy a grow light that reports PPFD at a given distance. At the very least, if it reports PAR, you can find calculators online that will do an approximate conversion based on basic assumptions. You can do an even more approximate conversation based on wattage (not voltage!) given some assumptions about efficiency and the spectrum of the light. Make sure you’re using the actual wattage, not “wattage equivalent,” which is marketing BS-speak for “how many watts it would take to generate this much light using an older, less efficient bulb.”
If the grow light doesn’t report PPF/PAR or PPFD, then it’s probably a low quality grow light. But you may have to dig a little to find this information, because even grow light distributors know that most consumers do not know about PPFD.
Carnivoro [has a chart](https://www.carnivero.com/pages/grow-light-ppfd-recommendations?srsltid=AfmBOopVjL-0a9LSE0nbWd0idGLncxf2o0Lr1_QswEHLGDt1DutMggAX) for PPFD by plant genus. Unfortunately, sarracenia are extremely high light plants, and their geometry makes them tricky.
