LED heat question

[grg61458]

I'm currently using an HTG 240 watt full spectrum LED, My temp in the grow space is between 89 and 93 degrees most of the time with multiple fans, Is this acceptable?

It will work but is not optimum.

Thanks that what I was thinking.

yea, id try to run a little cooler if possible unless you can supplement your area with CO2, I hear that helps raise the heat levels plants can operate well in.

Also, is it your LED pumping out that heat? I run an Advanced panel and even after being on for weeks 24/7 I can touch any part of it with no problem at all. Yours have sinks on it, or just the panel with the leds on it?

I'd shoot for 70-80F, why is your space so hot if your using LED?

It doesn't feel warm around it. Light is intense though. Notice plants drooping now since I put them under. Just raised it considerably, see what happens. I have a panel with LEDs on it.

You really want to keep your room around 75-80F with 40-60%humidity. If you cant keep it in that range,make sure you are using silica, it will make your plant cells nice and tight and will make your plants able to deal with heat stress and other stress that may come along. which is what will happen to your plants if you keep them at high temps. I like to use silica by dyan-gro they have been around for years and a 1 quart does not cost to much. pick some up at your hydro store or online: http://www.amazon.com/Dyna-Gro-Pro-tekt-Supplement-Discontinued-Manufacturer/dp/B000E1VZHC

Also remember to keep those girl WATERED.. even if your not feeding them,water them at least.
it will help with them looking droopy
Hope all goes well for your garden

I have Mineral magic from GHE : http://gb.eurohydro.com/mineral_magic.html
This willl work?

that is too high in my opinion, but it does seem odd that it would be that high if you have fans.

I assume you have fresh air coming into the room and an out exhaust to circulate the air, as opposed to just merely moving hot air

I have noticed the placement of my thermometer can make a huge difference....if the face is towards the light you get a higher reading

I use two, one near the lower branches and one near the cola height, so you get an overall average of the room....and position the back of the thermometer towards the lights

Hey there yes this kind of silica will do the same as the one i told the guy above. Just remember to mix this silica in your water first,before adding any other nutes. are you running hydro??? or soil?? if your running hydro you CAN NOT use micro-organisms in your grow.... But your using soil this stuff will help in the growth of micro-organisms.

Yea read about microorganism yea ... in my 1st runn i was DWC and used both with mediocre results... plants was rly healty but low yield, and roots was so so small....
it's there a specific time when to use?
Because i read about silica can slightly increase P uptake and can cause premature ripening when used early vegg.
it's that true? Or just 1 of the bullshit on net?

i use the silica all the though the grow untill your last two week of flower,this is a good time to start using a Sweetener like these ones from GH ( http://generalhydroponics.com/site/index.php/products/supplements/floranectar/ )

yes when using mineral magic, it will increase nute uptake all around. Well P does not start pre-flower the only thing that will start flower is a 12/12 light schedule P & K do help in the flower process. But in vegg P is good for your plants root growth.

Thnx man...more experience is always welcome

make sure that you are not placing your thermometer in direct light cover it more in the shade or under something to get the temp!
