You need to block them from direct light, shading them with a bit of white card stops the light from heating the actual device so it only reads the air temp.
Even though led has low radiant heat. It can still throw off the readings
I'd fucking shoot the cunts personally.
If they want notoriety they can have it.
Then again , I've got far more time for trees, nature and history than I have for people.
Present company excluded of course.
You've provided almost no information.
Is this soil or coco?
What is the 600w light?
Is it dimmed?
How many hours light?
What is the humidity?
What is the temperature?
How much water are you giving her and how often?
I know a guy that runs a few of them.
He likes them.
I have more expensive lights, can't really tell any difference in yield, I've never tried testing them against mine with a light meter.
I don't believe the umols per joule they advertise, but they create nice plants regardless.
So first thing I'd do is shoot for 80 degrees fahrenheit in veg.
Personally If I veg with my leds I run them about 25- 50% power @18" distance.
I find my plants are happier like that, they don't show any red stems, or signs of stress.
Then crank them up to 100% the day I flip to flower...
I'd personally recommend a good ec meter and cheap ph drops, because the latter is always accurate.
Everything else has been covered in the previous posts
300umol at 24/7.. that's not good, add In the lack of nutrients, the RO water with no buffering ..I'm surprised they ain't dead.
Get your water and add your calmag at suggested rate for ro water, add your nutrients and ph it.
Good choice!
They've got a coating for everything ..
One of the best things I did in my current place was install a sink.
Though couldn't get hose to seal nice so ended up putting a washer supply on the cold water pipe too.
Well it sounds like a cracking plan dude.
Looking forward to seeing it come together.
Can't add much value to this conversation, I first started growing long ago with NFT and that's kind of like those Danish trays , but you have capillary mats instead of rockwool slab.
You have constant water...
Only just seen your reply.
If there's something faulty have you tried contacting them?
Its worth checking.
I know they're real keen on customer service.
I've never ran his gear but it's a name synonymous with good genetics so it seems like a strange move, but if he's wanting to make more on the pack then that would make sense I suppose.
Interesting things though, looks like air or is it humidity been pumped through the vertical bars.
Can't see the point but there's a sucker born every minute
