far red

Hello everyone from Ukraine. I want to share my photos, experience and write at least. I am a batan and the topic of growing indoors has become very interesting to me. I had to study a lot from batanics to electricity, light and a bunch of everything I had to do in the current situation in the...

Hello everyone! I have been reading a lot about UV supplemental lighting and the use of far red for EndOfDay lightning and for utilizing the Emerson effect. As I am upgrading my micro grow right now, I want to experiment with UV and farred. After doing my research I still have some questions...

Hi guys, I've just received 2x 30watt 730nm cree LED light bars Would I be causing the plants to shock if I introduce the lighting in week 5 of flower? I have a 2mx2m tent Worried introducing a new light cycle this far into flower might shock them and turn hermie. Thoughts?

I'm about a month out from having the budget for my DIY bloom build and I'm looking to finalize my design/start ordering a few parts here and there as I have the $$. Planning on using these 44" samsung F strips (could be persuaded to change based on pricing BUT I like how condensed these LED...

I want to add adequate far red as well as royal blue. I don't want really want to use pucks because of the LED spacing. I'd rather build my own strips with individual LEDs if there isn't a great solution already. I plan to lay the QB96's out according to @Or_Gro's pics/info from GC in the...

Well, ...Hi all, you may remember a user called STELTHY ....well...10 years has passed, ....AND I AM BACK Ive left it so long since my RIU acc. was hacked and I lost a shit ton of pics over 130 pages of journal entries.. And in true STELTHY style I am once again putting more thought into my...

The question of how much of a certain color is often asked. I'm not professing to know the exact ratios, but attached is a little excel file to help you figure it out. You only need to enter the number of chips, your desired brightness from 0 - 5 and then a custom efficiency if the LEDs are...

Hi @Randomblame , I've ordered 4 QB 96s for my 4x4 and would like to know how many QB3s to install for the proper ratio of Far red light. Also what are your guidelines regarding timing and spacing the far reds for emerson effect and flower initiation? Thanks!

I've been thinking about picking up a Far Red board for EoD when I switch to flower. Was thinking about picking up a couple boards from HLG, but balked a bit at paying another shipping charge (I just got in another QB 288 last week to put together a dedicated grow light, wish I had thought of...

After setting up my Far Red LED Initiator Pucks I accidentally plugged them into the wrong set of timers and when my lights went off yesterday at 4 PM the far red lights stayed on and instead of putting my girls into sleep faster I don’t think they went to bed at all . I am just waking up now...

Hey guys, so Im looking into getting some supplemental lighting to add to my set up and had some questions. Im looking at both the Exotic Supplement board and Emerson board from RapidLED. Considering doing a DIY supplement light though as Im not sure the benefits of the IR spectrum that comes...

Hello RIU! Been lurking this forum for a few months and I finally decided to join and start a journal. Here is my bloom cabinet: It started life as a Supercloset Supernova. As everyone warned me, Superclosets come with the cheapest parts available to start a grow, all in a metal storage...

Almost all of my new plants are praying aggressively the entire lights on, I feel like its light stress but I have the light turned way down and way above the canopy. I am running the far red puck at lights on and off, I'm wondering if I should only run it at lights off. I already found out...

Setting up for a 4x4 grow, under a pair of Timber 48SAMS, a pair of HLG QB-35s, single 4’ Agromax T-5 uva-b, and a single 4’ GrowBright far-red initiatiator. Will be doing ~ 65 DLI, with CO2, and these mainlined NYC Diesels and Super Silver Hazes: as soon as they hit 12” height. Wish me luck!

3 week old seedling, local strain. Been under a far red spectrum LED for the last few days. I realize this isn't the spectrum it needs at this stage but it's what I have. Going under 3500K soon. Temps are between 50 and 65. Just receiving water. Any idea why it turned so purple?
