Yeah that's not warm enough man. For leds. And your pots are probably cold. So the roots are really cold. Slowing growth and everything else. You might get some heating pads. And set them under the pots. To warm up your media. Like you do cuts n germing seeds.It's kinda a cab...just a wire rack wrapped with some panda film...very cheesy but all I had until I can build a small cab. I want to get a 36w x 24D x 52H cab soon. The room is a 12x12 and it's about 64 with no lights and the leds seem to get it to about 68/69F. The getto cab is about 73-75F with the leds in it which I thought would be enough. I was thinking of getting a cheap grow tent to hold me over until I can build a nice wood cab....do the tents retain heat better? A 36W x 24 D tent would be enough i think.
Awesome...!Yeah that's not warm enough man. For leds. And your pots are probably cold. So the roots are really cold. Slowing growth and everything else. You might get some heating pads. And set them under the pots. To warm up your media. Like you do cuts n germing seeds.
I've faught cold temps for the last month and a half. We have all 4 seasons here. Winter usually lasts about 2 months here. And it usually hangs around 20-38° throughout winter. But so far this year it hasnt been above 10° my flowering tents got hit bc no lights for 12hrs. I run lights on at night. Bc that's when it's the coldest. I run 4pm to 4am. I get up at 530am for work. A few times I got up fir work and in the tents was 40° they dont like that cold ass shit at night. Lol. So I put little heaters on a temp sensors. That kick the heaters on n off as needed. With sonoffs. They are cheap. And you can control and check temp/humidity from your phone.Awesome...!
I think it may be time to transplant into something biggerHere some pics. It looks like nute issues but if I put them under the hps they start to improve. I've tried these plants in hempy and now soil with basically the same results. My ppm is about 600M with dyna gro foliage pro with a tap starting at 200ppm.
I said i've tried adjusting the nutes from less to more than I normally due. It may be nute burn and if it is then it's something to do with the lighting and environment and how they interact.
I've grown several grows with the same ferts with the same starting and final ppm / ph with success. The only difference this grow is the light.
Those pics of the plants I posted are starting to look better and getting more green color to them and all I did is put them under the HPS..so they still have the same nute strength they had under the leds.
I can feed them exactly the same way with zero changes and they always get that way under led and then recover under hps it's reproducible.
I'm thinking that the low room temp and the humidity played a big part in this and probably didn't let the plant metabolize properly and the nutes built up and burned it.
It's just a theory if it's really nute burn which a few have mentioned. It's just confusing that a light change fixes it. I think the IR in the hps compensates for the low room temp and heats the leaf material up since it penetrates it. I guess this might open the soma more..don't know. Thanks for your input.
