Quick question guys

[Deforced]

I'm not sure if this makes sense but when I seem to grow taller plants I seem to have heat issues, would this be a cause? I'm in a 2m tall tent and the plants are around 1.8m. They are rather bushy too which I defoliated. Thanks

Are you taking the temperature at the same spot each time or at canopy level? Because taller plants will be closer to the light which is always gonna be hotter the closer they get to the light.

Also, bigger plants could reduce air movement too.

Well, I've got a thermostat at the canopy level and it seems to be 27.5°C they are also in flower. Is this a little high? Thanks

Are you using led lights?

27.5 is ok for veg and early flower but you want to lower it a bit after starting 4th week of flower. Around 25C mid to late flower then lower it more last week. Also you could give it something to stop your plant from getting that tall

I'm running 3x600w hps (dimlux) lights and 1x600w led. It's a 2.4x2.4x2m tent, 12inch extraction and 6inch intake.

I would keep the plants 60cm away from the lights specially the hps as it gives off heat and can damage the plants if they get too close and 20cm is pretty close

Ok, so as I've got 600w dimmable lights if I dimmed them down to 400w it would produce less heat. But doing this would it reduce my yeilds dramatically or would I not really see much of a difference. I got suggested by a fellow grower not to dim 600w lights because it reduces the spectrum alot. Thanks

Well once you hit flower you want to gradually increase your light but in this case you should just stop the growth of your plants. Personally I give my plant phosphoload once at the end of 2nd week to stop them from stretching. Also you have any pictures? Lots of people here have more knowledge than me when it comes to lights im sure they will help you out soon but posting few pics will give a better understanding

 

[Deforced]

No problem. I will grab some pics, im pretty screwed for raising the lights anymore now! They are at the roof of the tent. I'm week 3flower mainly indica dom plants. I will grab a pic now
