Well to answer ur question I don't live in the us and my regular daily temps outside is 28-33C so in my closed up room it Wud get a lot hotter ac is a must. I have tried without ac and as soon as the plants get leaves they die. Also tried with ac but my res temps were a bit high plants got root...

Ok lemmi just make sure I'm reading right, are u sayin that u strive to have the temps the same or u try to have as much difference between lights on and off?

My ac runs while my lights are on for 18hrs a day at lights off the ac also goes off but comes on every hr and a half to cool the room a bit. My question is my room temps are basically the same lights off or on Wud that cause a problem

Just started a grow and my temp are mostly ok, room between 72-76 and res between 65-70. I can't maintain ac for 24hours so I have to shut it down for 3 hours a day the times vary but it is during light on and off. As the ac is off the temps rise room to 81-85 and res is around 73-78. Would...

I just started a grow and my temps are mostly on the good side, but I can't maintain the ac all day to keep my temps on the nice side. Is it ok that for about 3hrs a day that my reservoir temps climb to about 75 and room temps to about 81? Normally res is between 65 and 70 and room is 72-76. Now...

No offense taken, also in ur response I am guessing that I can run my DIY co2 without any issues

I am tryin dwc and to help control res temps I have a PC fan blowing on my res. I also use co2 with the bottle and yeast method. After every hour of intake and exhaust being on they shut off for half hour to allow plants access to the co2. Since my res fan is sucking air from inside the grow...

to address the concerns 1) the fan in the pic is just one of the fans to blow the plants there is a hole for fresh air but no fan but there is a fan for exhaust 2) also i had 205watts of 6500k light on my plants b4 at 8 inches above the plants and the leave wud go yellow *not burnt but they...

ill start off by saying i think i have tried everything... now what has me lost is i tried growing other plants in the same environment and they have grown quite well just some examples of lettuce and local celery, now this is the same environment same nutes same ph same soil or water as the...

weeds u say ? too hot ? over watering maybe

basically i wanna know if i should start over or work to try save these plants... i apologize for pic quality upfront. my original setup started off with a few 9watt cfl which i found to be not enough so i went out and bought some upgrades cuz my plants were so small. original setup...

can i add nutes to plants recoverin from ph burns

is there a ratio for the air stone vs size of reservoir? like can i have a 2" airstone in a 10 gallon tub ? can i add ph down to the reservoir while the plants are still in it ? is there any other way to get thicker stems other than a fan blowing on the plants? does it make a difference if my...

so i was reading that too much light can bleach the leaves of my plant, lack of nitro can also have a similar effect. my plants started loosing the green color in the leaves so i added a low strength nute solution to water, i am guessing if the solution was too strong the roots would be the...

just an update, i got my thermometer and i also got AC around the same time, with the ac on 23 degrees C my grow area is around 73 lights off and 85 lights on, so i believe that without this ac my room cud have been well over 100 degrees, so heat was my problem after all. the new seeds i popped...
