If was you, I'd get the rspec with two boards, ask the vendor or HLG if they can ship it with a 185 instead of a 240. Mount it all the way on the top of your tent and dont worry about it again. Growerslights has some "100W" that i like better, its a 80H 288 with a heatsink. If you get those you...

Still harvesting one of my first rspecs. Like i said it was a bit burnt and slow to finish. I did a slow harvest on it over 3 weeks, top to bottom. Got about 170g and a bunch of popcorn. Bit better than the V2, but like i was saying earlier it burnt my plants up and stretched and matured them...

Yeah, i get that. But its a simple cheap plug and play UV light, that also kills bugs. Trying to find low powered and a good profile fit for small grows is almost impossible. Ive wanted to mix some in my 2x2 but theres now way until HLG put sthem on the boards with some new fancy leds. Im pretty...

Im planning on building a new type of lighting system i havent seen for sale, would like some input. I know this is going to sound ghetto but seriously. I want to combine air cooling, wind sway and light movement effects all in one package. The quantum board idea of spreading light out and...

Idk, 12 inches atleast, one or two colas are closer but not within 6 inches. My v2s grow within 2 inches sometimes with no problems

Na. Everythings good. I mix my nutes in a large bucket and use it feed multiple plants. This is like the third plant ive grown under these. The first i started on the rspec about week 5 and it came out real real weird so i started feeding it some random micronutrients and it came out stout as...

Im using 135w kits in 2x2s. 3 for 12/12, v1,v2 and rspec. I have a 80H on a v1 in my veg tent. The v1 135w kit runs a "preflower" tent at 14 hours. I take one from the veg, put it in the preflower for 2 weeks, until it develops a good canopy, take clones then transfer it either under the v2 or...

Yeah well thats what figured, i got the rspec expecting it would bring me some bag appeal with a lot more purples. The ones claiming that its a creates a shorter harvest time though, im not sure thats a plus. If we could take a plant that's going to grow for 7 weeks and harvest 100g, what if we...

The plants i get out of my veg tent all have deep purple stems, even though its not strong light, the effect accumulates over time. These are mother plants that are constantly cut back and exposing the stems to light. The cutting also causes stress that pushes the plant to produce anthocyanins...

Green under the buds. Heres one showing "pigment dyed yellow orange leaves" on the top and green under the canopy on my rspecs due to the 660. If it was from just the end of lifecycle or N it would start from the bottom up, not top down.

I didnt say there was anything wrong with purple stems, some else had mentioned that earlier but im not buying that. Im not aware that stems breath or do photosynthesis. Im just saying that they get purple from high light, certain wavelengths of light. Its not neccesarily related to deficiencys...

Im saying its a combination of both higher light AND the spectrum. Its not enough of either to make a huge difference but combined it is. Managing vpd is crucial to optimizing your grow and its very underestimated as a key factor in success. If you running high humidity and temperature thats...

"The evidence presented here that anthocyanins protect senescing red-osier dogwood leaves from excess light is based on laboratory studies in which we were able to impose on red- and yellow-senescing leaves identical treatments of high light intensity. We based our light treatments on the...

Im not going to argue on UV, they do emit UV, thats how the work, they have a coating that is SUPPOSED to stop uv. They also have a peak wavelength of green light that appears to be the best wavelength for anthocyanins right there at 550nm. Why the other source says that anthocyanins peak at red...

"Morphological responses of American cranberry (Vacciniummacrocarpon Ait, Ericaceae) to different light conditions (red,far-red, white light and sunlight) were examined. Root growth and development,stem elongation, leaf enlargement, de-etiolation of stem and leaf, flower budformation, and...

"illustrated that red light activates the phytochrome photoreceptor which enforces the delocalization of the nucleus and modulates gene expression" https://biomedres.us/fulltexts/BJSTR.MS.ID.002467.php What im saying is that rspec is a finishing light, an amazing one but along with that i...

You dont have to have a published scientific paper to make it true. Theres not much research on cannabis at all and were talking about a uncommon phenomenon specific to certain environments. When plants are stretching they arent going to purple. When they slow down they do. Now when i veg a...

Some flouros have very high UV.

Purpling stems are going to depend on how old they are, how much light they recieve. Canopys are actually amazing at filtering light, its what theyre designed to do. Purpling stems come about for many reasons but its essentially a sunburn in this case that were talking about. Purple/anthocyanin...

Yeah i try to keep them about 6inches from the very top of the tallest cola. I grow in 60 inch tents, i mount the lights to the top and let the plants grow up to them. I have fans mounted to my boards and decent ventilation, run co2. I also keep the humidity quite low with a combination of AC...
