Hey guys, so I've decided to get 2 boards with Cree XPE-3 Deep Red 660nm x 12 diodes and 1 board with Cree XPE-2 Far Red 730nm x 12 diodes. I plan to run the 2 x 660nm in series on one driver and the 730nm on another. The drivers I plan to get are: Mean Well HLG-60H-54A for the 2x 660nm boards...

Yep thats right. 1st ones i bought were legit HLG QB288 v1 (2x boards) with a HLG-240H-48A driver, 2nd ones were from China and has the LM301B LEDs on it. So im starting to think I may try adding some 660nm to my garden because it can't really do any harm and even if 660nm doesn't have any...

Thanks again :D I'll give just the A + B a shot. Last water change I had the EC at I think .6 which then dropped to .3 before I replaced the water with EC of .9 (including the additives). Atm I've got EC 0.8 (with cal-mag A+B and a bit of silica) after diluting it a bit. Hopefully it bounces...

Ive got a Meanwell HLG-240-48 powering two boards and an ELG-240-48 powering two boards. Not particularly keen to replace the boards as it will still be quite expensive and just add to waste.. besides from what I can see I stand to gain around 10% efficiency and like 2% more PAR. Perhaps the...

Yeh, I think im gonna go that way... Just gonna use A + B, Cal - Mag, Greatwhite, Mammoth and maybe some Silica (Dutch Masters Gold I have left over). I think ill just use up the rest of this H&G stuff and then give Current Culture a try. Have heard they make the best nutes for DWC.

Hey mate, thanks for the suggestion. From what I've read (really mostly watched on youtube haha), emerson effect stops being effective at higher PPFDs and I'll be running 4 qb 288s for 1 plant at flower, so I don't think the emerson effect will do anything. Also, from what I've read you really...

Super late update :) So the grow ended pretty successfully, I think I got around 11oz from it so pretty happy. The bud was nice and frosty too, probably the most frosty I've done to date. I would put this extra frostyness down to increased oxygenation in the res along with the bios - great...

Thanks for the info mate. After much research I think I'll just give the far red at sunset treatment a try (with 13 hour day) and then maybe look to add UV in the future. One thing at a time :)

Interesting. I was thinking of trying to replicate HLG 60. Did you just buy the diodes from RapidLED and then solder them together on a bigger board? I assume you run the far reds at the end of the day only or do you run them during the day too? Do you run the normal reds at the start of the day...

Hey guys, I've been reading a bit about LEDs with far red light and other wavelengths (660nm Red, Blue and UV). I've also noticed that most of the new quantum boards come with red lights installed in them too. So I'm looking to upgrade my garden with some more wavelengths :) So far I have 4x...

Update: So after 3 days of flushing the EC dropped down to 0.1. I also noticed that it drank a lot of water during the flush... In this water change I've put in only Aquaflakes A + B, Cal Mag and Great white and Mammoth bennies. EC was at 1.0 when I added the water, its now at 0.9. PH seems to...

No stress mate, its been a learning experience for everyone involved lol. I'm very appreciative of your help and input even if it didn't fully fix the problem! Thanks Jondamon for those EC figures! I'll use them after I've finished my 3 day flush. So I've just changed the water with plain PHed...

So im not sure if the problem is getting better... The leaves still seem to be doing the same thing - they look healthy when they're new growth, slowly develop a few brown spots as they grow then eventually end up dry, brittle and brown. The rest of the plant looks healthy though, the stem is...

Thanks for the advice guys. I think ill just ditch the humidifier and not worry about VPD. Buttons on the humidifier need to be pressed every time the humidifier is powered on so putting it on the light timer wouldn't work. The temperature and humidity are being measured by an external probe...

Hey guys, Atm my tent is at about 25 C and humidity at about 40% RH Here are some graphs of recent RH and temperature: The dips and spikes are when the lights are off and the exhaust fan is cycling every 15 minutes. When I run my humidifier the humidity gets too high when lights are off...

Thanks mate. Just set ph to 5.7 and EC to 1.9 (dont want to go lower because of water level, will try lower EC next water change) I took some close up pictures of the leaves that I pulled off the plant too.

Well that all makes sense. What is a good level of EC to use through Veg and Flower? I was following the EC recommended by House and Garden.

Thoughts on using a temperature switch to turn exhaust fan on when it goes above 25 degrees and turn the heater on when it goes below 25 degrees?

I just realised I have a temperature switch which will allow me to turn the heater on under a certain temperature (say 25 C) and the exhaust fan on over that temperature. Do you think it is a good idea to set this up to keep the temp a bit higher (atm its around 17 with 15 minute cycling) or is...

I've got the same Iceline as that lol its connects each side of my res to a water chiller. Is the general consensus that its better to use lower amounts of nutes? I thought that way and did so originally in my first couple of grows. I even critisised my mate when he was running an EC of around...
