I would think an analysis of THC content of the final product would be the most revealing, as that's the compound that is produces in response to UVB. I have read quite a few anecdotal accounts of people growing with supplemental reptile bulbs, but I prefer images and statistical analysis. As...

Oh my goodness. Tension! I, for one, would love to see a side by side grow off between these two companies. I've seen good things from both. Just to be clear, Eraserhead, the new Area51 lights will meet the photosynthetic requirements of the plants below them using white LEDs with different...

Does she realize it's just a plant? Goodness.

Perhaps I'm beating a dead horse by resurrecting this thread, but I'm intrigued. Does anyone have a documented grow with a Solarstorm light? I've read in a few places that by placing these lights at the required distance from the canopy (due to the LEDs), the amount of UVB that reaches the...

You do realize fans and heatsinks aren't mutually exclusive within lights? A lot of companies use both.

Also keep in mind it may take a round or two (in my opinion, anyways) to start getting solid results under LED. There are some changes to be made when switching to LED because the lights kick off much less heat than traditional lighting, so your watering regimine will likely change, and you may...

If you want an example, check out the thread in my sig. I've listed the yields from my last grow, Sour D, SLH, OG Kush, and Sour Kush under a couple of black dog platinums. All the stats are there.

Here is the link.

I just posted another video on my youtube page, it's an update of sorts from the end of flowering. As I said earlier in this journal, I'm very much an iMovie novice so keep that in mind when you watch it :) Feedback welcome!

Understood. To answer your question, in my opinion, it will not be beneficial enough to justify spending any money on it, particularly if you are on a budget. I would just stick with what you have and put that money towards saving for a better unit, or something else.

There is a threshold for wattage per area. Go over the ideal amount, and you're wasting energy, money, and potentially harming your plants. For a 3x3 area, I recommend approx. 300 watts of high quality spectrum and intensity. Keep your humidity, CO2, pH, ppm, root temp in check, you should be...

Aquarium lights are not designed to grow MMJ. I advise you to spend a bit more on a light that is proven. Look around this forum for some of the bigger names, then check out the company websites. Spectral quality, intensity, footprint, quality components... if you spend a little more on a...

Always, always test pH and ppm. Most common problem I see is people burning young plants with overly concentrated nutrient solutions.

I don't think it's proof that we've evolved from animals. Ants and humans are considered the only two species on the planet that war with their own species to such an egregious extent. I think there are a lot of factors that go into it. Technology (read Jared Diamond), fear, chemical...

Growers House has the run down of PAR measurements for a few lights on their website. I think it's in their blog.

How many plants are you trying to fit in there?

Crazy bleaching. I've seen it happen before, always because the light was too close. I hypothesize the higher frequency wavelengths coming out of the panel lyse the pigments in the parts of the plant that are too close to the light.

I would buy a pH and ppm test kit and use it often. Also, I don't know where you live but pulling air from your loft doesn't sound like a good idea, especially come summer. Heat rises.

74-78 degrees shouldnt cause heat shock... Do you have proper air flow? do you test pH and ppm of your nutrient solutions? Two feet seems like they should be ok.

OG Kush for sure.
