Yes, they are used as side-lighting and supplemental red and far for LEDs that don't already have it.

Yes, this is still happening! ^ So is this you putting your hand up for them? Sorry if I'm a bit slow to get it.

I know you're out there, so first in first served! :mrgreen: One of our Kiwi customers @Scuzzman has kindly offered to donate a set of Buddies to someone local (in New Zealand) who could use them. No strings attached. On offer is 1x string of PC Red Buddies and 1x string of 4000K CRI95 White...

Looking healthy mate. Sorry, no ETA on the blue Buddies yet. I know Teknik has been trialling LEDs for them and has a design ready, but not sure when they go into production. I will ask and report back later.

Hi mate, you make a very valid point but we're in that twilight zone at the moment where we are just big enough to supply a modest demand for LED kits, but not big enough to start exporting on a larger scale. Even with a US distributor, we need to be able to make enough boards at a price that is...

The answer to that one is 6.

I'm not sure what the question is, but the answer is "42". Anyone who has read The Hitchiker's Guide to the Galaxy will know what I mean ;)

4.5' x 4.5' or 1.35m x 1.35m I'm not sure, but I do know he vegs separately, so the flowering tent is always full. As soon as one run is finished, plants go in and start flowering for the next run. I'm guessing he vegs for 4-5 weeks. This isn't one of Prawn's grows, but I do know he mentored...

Results are in on this grow. Just over 50oz again from 900W. The plants on the right under the High light 420s finished four days earlier than the ones on the left under the High Red + UVB bulbs. High Red yield was 462 grams and HL420 yield was 550 grams. The two plants in the middle yielded...

He does, yes. That's why he runs the 6% bulbs and not something stronger. UVB breaks down THC as the plant produces more of it, so it's a balancing act between stressing the plant with UVB to produce more cannabinoids and destroying those cannabinoids with UVB exposure as they are produced. The...

You should. You might be very surprised at how well they grow.

Here is the same set-up at 50cm and 60cm hang heights, which would cover all the different levels of canopy in the photos. For the record, the hand-held spectrometer readings were a bit lower than these PAR maps are showing, but were all within about 100 PPFD. The tent was not fully closed...

We also measured the light with a PAR meter/spectrometer and the results were pretty close to the DIALux simulations with 70% reflective walls. That seems about right for this particualt tent, as it's a cheapy and the walls do not appear to be as reflective as other tents we've seen. I think the...

Here is something that might interest you. On the left we have the original High Red boards with 6% UVB Arcadia bulbs and on the right are the new High Light 420 boards. This is in a 4.5' x 4.5' running a total of 900w (450W at each set of boards). There are indicas on each side and a couple of...

It's true the panels are optimised for flowering – many of the grow reports we've had on the new boards are showing reduced flowering times by 5-7 days with the same or increased yields (which we attribute to the extra far red) – but a "true" full spectrum should also outperform other lights in...

What is interesting is if you move the lights closer together at 1m canopy height, you pick up 20 PPFD with a better overall spread of light and almost no loss of light in the corners. This is due to less reflective wall losses. Here is one of my favourite 1.2m x 1.2m layouts. This is 6x...

As requested, here is a 50cm band – from 0.5m-1m canopy height. You can see that for each 10cm (4") there is an average loss of about 50 PPFD. From a peak 1350 PPFD at an average 1192 PPFD, intensity drops off to a peak of 1000 PPFD at an average of 940 PPFD. This represents a peak loss of 350...

It depends how you grow. For single plant grows it can be advantageous to have more light in the middle. For scrogs, you can cultivate in a "cup" shape – lower in the middle, higher around the edges – and take advatage of the vertical distribution of light that hits the sides of the plants that...

The only issue with the "magic band" concept is that once you throw a plant into the mix, your "light penetration" levels cannot be easily measured. Light does not drop off as it travels – a photon is a photon until it interacts with another object. So it either gets absorbed by the plant...
