Yes but the t5s are almost touching the seedlings, the led is a good bit away

Hey Cobs, what's your feed strength during this period? Thanks

I'm not 100% buying this theory tbh. When I used T5s I used to have a fan blowing through the vents and could touch the bulb with the back of my fingers. They were at least as cool as my leds, if not a bit cooler. It's possible it has something to do with the diffuse light shining through the...

The higher strength feeding is definitely paying off though. I've been giving them 2.0ec and it's made a huge difference, especially to the young clones that I just started off on this feed. I'll get some pics up soon

I understand this mate, but there's more going on than hardening off. I used to take clones and put them straight under high intensity lights and watch them explode. There's clearly a difference using LED lights that is specific to LED. There's no doubt about it.

Thanks @Moflow This is exactly what I'm talking about. And I notice the same thing when I pot up into final pots, around 20-30L or so... There's got to be something to this. Maybe the plant needs more root mass to effectively process the light, I don't know. Anyway, I've watered them with...

How's things bud Clones my man So no, this is not the spectrum its how youre adapting to it. I'm sure it's my own fault, I'm not blaming LED, I'm just wondering if there's things that can mitigate the issues is all. What strength of feed are you finding is best under led from seed onwards...

It's staying wet a lot longer tbh, but this doesn't seem to be an issue once they get fully going. It's this initial struggle that really frustrates me. I need consistency and I'm thinking that there's something I keep forgetting to do, from grow to grow, because I don't have a new blueprint so...

Thanks for all the replies, I appreciate it. From what age are you feeding at that strength? And, how different is that from when you were under HID? Did you have issues trying to feed at the same strength you did using the old halides? This might be where I'm going wrong. Slow growth...

Well, my space is either a tent downstairs, or the attic, both of which are in controllable environments, so I can raise or lower the temps and RH as needed. My feed strength of canna A/B is around 1.4... I added a bit of epsoms and that seemed to perk them up, but not to the point where they're...

Honestly I'm thinking at this point to just get myself a t5 fluoro and go back to doing it old school. In all my years growing, I just put plants into coir, fed them 1.0ec of a base feed, and stuck the fluorescent light on them and watched them boom. two weeks and a pot up later and I'm almost...

If you're not doing better numbers under the LEDs, you're not doing LEDs properly

I'm setting up something similar and was gonna use a circulation booster pump with auto on/off, but not sure it would work. Nobody seems to know the answer to this question

Did anyone ever find a solution to this?

Cool, thanks too Been listening to the a podcast with Shane from micro on it talking about how only about 10% blue Is needed to regulate growth, which anything over 2700k is, so rest might as well be red which is more photosynthetically actually. Any thoughts on that?

Sorry, they've told me as standard it's a mix of 3000k and 5000k at an 11 : 4 ratio but that it's customisable

Yea, have a look here, just under the par maps Kingbrite 1000W

Thanks for the replies, I might ask about switching to osrams. But might it be an idea to ask them to switch to a lower colour main diode? If so what would you recommend?

But back to my original question, what's the consensus on the 660 & 730 diodes? What would yall choose? More of the Evo diodes, or Osram over the Epistar? Here are the exact options 1. LM301H EVO+Osr 660nm/730nm(282pcs/bar: 270+9+3), 282*10=2820pcs 2. LM301H EVO+Osr 660nm/730nm(320pcs/bar...

I don't know, I'm thinking Kingbrite have built up a solid enough reputation by now to be trusted somewhat, what do you think? The total cost is £600 delivered for the 1000w or £500 for the 800w, which is decent enough relative to what else I can get for that price. It's the tilting lights...
