ok so every one always says that you have to keep the heat below 90 but my plants are 20 days old and i just got a temp/humidity sensor and it reads 93f and humidity of 48..

my question is since they have grown up in this heat for 20 days and they are healty should i even worry about cooling the room


Ps. the room is 78.9F but under the lights is 93F

Radient heat is different than ambient temp. Just to clarify. 93 in direct light from an HID seem pretty normal depending on distance. Check various parts of the grow room with the sensor in the shade.

Fox does make a good point.I asumed he was giving ambient temps of the grow room not direct which was a dummy move to assume

once the temp goes over 70-75 degrees i think, the buds just get more airy and less tight.. the closer to 70 degrees the tighter and more dense the buds are.. the plants themselves can grow in heat np.. look at mexico, africa etc.. you just sacrifice quality and quantity.

Ryan those cups wont help really at all. If the room was lets say 8x8x8 then you would need about 4-6 of the 5 gallon co2 boost buckets to keep the co2 around 1500 and unless you can keep it aroun the 1500 ppm when lights are on your not gonna benefit from co2

thanks for the input but.. i dont know if this makes a diffrence but i have tubes conected to airlocks on the yeast cups and the tubes transfer the co2 right to the bottoms of the plants all the yeast cups are in a closed system and all conceted...

Got a temperature question for you. Do you think a high temp (>75f) in a hydro grow res would cause a ph drop?

Fletch: No noticeable benefits from co lower then 900 ppm really at all and co2 is heavier then air and should be up high and fall down onto the plants with a fan on the ground pointing up to recirculate the co2 back up as it falls and gathers to the floor so the leaves can get it and use it. At the base its definately not even getting a chnace to be used
