Shengsite LED Gooseneck 20w grow light review
If you follow (or read) my Amazon reviews you can see that I've been running numerous agricultural/botanical science experiments for the last few years. I have literally purchased almost every single "LED Grow Light" on Amazon. I continue to purchase them and test them as others request. I have tested all of the 300-600w, all the 36w, 48w, and 60w "LED grow light bulbs", all the way up to to the majority of the 600-2000W LED panels. I have been been running everything in two laboratories with controlled environments and controlled conditions. I use an Apogee Quantum Par meter and several other sensors as testing redundancies. You can find more details on my laboratory equipment and explanations in the full review on Amazon: https://www.amazon.com/gp/customer-re... This is the (Amazon) video review on the Shengsite 20w LED Gooseneck grow light. If you don't want to read the lengthier review on Amazon here is a slightly condensed version: It is important to understand your plant's requirements when choosing a grow light. The plant in my video review is a Tradescantia Zebrina (species from Mexico) aka "Red Hill". There are many varieties of this species. Some grow only green, some grow green with hints or purple, and some like the one I found, grows vibrantly purple and pink with a glittery shimmer. The Red Hill prefers partial sun. I've experimented with this species quite a bit. Boosting c02 and giving it elevated nutrients doesn't cause this plant to bolt or increase the growth rate, it seems to do best with limited exposure (4-5 hours a day, never bothered to monitor the DLI) to lighting around 70-150 μmols. I mention all this because even though I have hundreds of grow lights to choose from, most of them are not made for early stage growth or for supplemental assistance, or simply they are (not-in-a-good-way) overqualified, pumping out too much heat or too much intensity. Utilizing a stronger light for less hours becomes a scheduling and photosynthetic mess with plants in the local area. Most LED grow lights simply don't allow you add a dimmer to them. So for all these dilemmas, the Shengsite 20w gooseneck grow light with built in timer, is a perfect solution. The light can be dimmed by holding the +/- button, however, for the test I left the light at Maximum.Using an Apogee Full spectrum smart Quantum sensor, the SQ-520: 561 μmols at 3cm (practically touching plant, but safe as the light emits very low heat) 220 micro moles at 1 inch 160 micro moles at 4 inches 70 micro moles at 8 inches 45 micro moles at 12 inches NA for anything beyond that.
