heat

Due to my growing situation I've had little control over heat - unfortunately my gut tells me this might be my undoing. Clones from a previous successful grow (donated by a friend) Indoor grow Grow is 8-9 weeks 16/8 then 9-9 weeks 12/12 Living Soil with organic supplements (Dr Greenthumbs)...

I have some sproutlings around a week old, they all sprouted under a small 50watt light, since they were all about an inch 1-2 inches tall already I decided to turn on my 400watt hps and forgot to ventilate my tent before leaving for work, i come home and 1 of them wilted really bad from heat...

Hey yall, been a long time since I've been on here. Im finally back in a space where I can garden and super grateful for it. Im just running into a few issues. Im located in a area that gets quite cold in winter 10F and having to grow in a garage space. Im currently setting up a 10x10 tent and a...

Good morning guys, about a week ago I entered flowering and am having quite a few problems with humidity. I have recently moved into a house that essentially has no doors so it's like all one room.. I have a dehumidifier with a tank capacity of 16 liters and it is supposed to cover 30m3 and it...

I’m in Texas and currently there’s a heat wave. My girls are 53 days old from seed. The temp is 96 degrees with a humidity of 45% and almost no wind (max 7mph). I put them out in the morning sun and they began to droop and look so sad. And I’m worried bc Morning is the coolest point of the...

I have a 3x3x6 grow tent in a barn(lol). with a 6 inch inline fan running 24/7 on 25% and growing in Happy Frog soil. I just switched to flowering and my humidity is at 75 and temp around 80. I want to get a dehumidifier but I am afraid it will make my tent even hotter. Any recommendations for...

I'm having an issue with a couple plants trying to throw male flowers on tops of bud growth, I've checked for light leaks MULTIPLE times, nothing, humidity is good almost always between 45-55%. Could heat/ too much light cause plants to herm? My temps never go above 83F-85F, although here lately...

Hey guys, As the title states I'm currently having some issues with maintaining the appropriate temperature ranges. I'm a grower from Malta and we recently passed the law to be able to cultivate up to 4 plants. In summer temps are ideal but during the winter I'm having some troubles... My...

Hey. I am growing in a DIY Grow box, basically a cardboard box with reflective material. However, I am having trouble keeping the temps below 28 Celsius at canopy level as my CFLs give too much heat for that small space and was wondering if just taking the box lid off is ok or is the lid...

Hey there, weed sages of the internet. After last year's grow went bust courtesy of my trigger happy watering and light mismeasurement, I've decided to try an outdoor grow instead as I generally have an easier time working with the sun. Based in Massachusetts and there's been some very hot days...

Hey guys I was curious if this is heat stress or if it’s just getting closer to flower (brownish hairs) room stays around 74-76 degrees during the day and a cool 65 at night with Rh around 45% LED light is about 28 inches from canopy

Currently running 4x 600w digital hps but having problems with the heat in my room. I already have an intake from outside and a large outtake fan so have had to turn them all down as an attempt to lower the temp (currently 33 c). what I am wondering is how much cooler would 4 led lights be...

Hey guys, I wanted to get the LED drivers for my Mars Hydro TSW 2000 light outside of my grow tent. I thought it might help reduce interior temperatures. I know some people hang drivers by the cords. I wasn't to crazy about that idea. But, I got to thinking having them on the carpeted floor...

My seedlings are yellowing some are gripping down but others twisting up. it was hitting 33 under 4 x400 hps so I’ve just turned them down to 250. ihad them under a t5 for two weeks prior. they have been in here a week just done a light mix of ph water at 1.3 nut mix is it the heat and is...

First grow, plants are coming along nicely. However its freaking hot in my room, 98-100 and that is with 2 portable ac units blowing in. the ac units are not pulling air from inside the grow room, they are in the other room. I think the ac units are creating a positive pressure issue due to...

My tent is 88 degrees with my new light. My plants look good besides two yellow spots on two leaves. I’m guessing they need calcium. I haven’t feed them anything besides water I’m the last week because they just recovered from nitrogen toxicity. I’d like to know if I should get a intake fan...

Hi there my temp in my tent is around 34 degrees and my outlet fan is not that powerful it’s 4 inch if I move to a more powerful 6 inch outlet will that help with the temperature my light is a 600w hps

I've seen a few posts on the forum about LED grows doing better at 80-85F, warmer than other lighting solutions. The search function is bringing up much and I was just wondering why this is.

Guys, thanks in advance! This is my first post on here and I'm on my second grow ever. I just upgraded from 2x 300w viparspectra to a MarsHydro TLS2000W grow light. I thought that this was supposed to produce a lot less heat but I still can't keep my tent under 80 degrees. It's indoors and the...

Everything was going good on my purple alien plant under a 600W HLG led and then bam. Right now I got issues I can probably fix. There’s yellow streaking starting to happen. What could be the issue ? Going on week 3.5 of flower under 600W. Temps have reached up to 87F due to AC issues. Could it...
