ok so i have 6 plants, 4 recently started flowering and 1 thats been flowering for about 2 weeks now.

I made a diy carbon filter, using 2 dryer sheets to keep the carbon inbetween the fan and the exhaust hole.

I made my filter yesturday afternoon and i noticed my box raised atleast 5 degrees F in the past day.

when i showed my 2 grow buddies (my 2 most trusted friends, one who used to grow n got arrested 4 it n one who wants as much to do with growing without actually growing it in his own place..) my biggest female, the one that was flowering for about 2-3 weeks, was all wilted and dried out today. i have a feelin it had something to do with the temp but the soil was also dry n my other plants arent like that.

should i try to re-adjust my filter for better exhaust or just water my plant more? idk where my thermometer is but i think as long as the plants dont touch the lights they will still be ok if i keep them watered regularily.. i also didnt give them alot of water after there 3 day weekend of me being away (i let them dry until the hour i left 4 the weekend n watered em with nutes) n when i watered yesturday morning i mighta not given em enough.

any ideas on what i should try to do.. any anywhere to get a good, cheap mesh material for a filter thats has alot more holes then dryer sheets, they are whats blockin my air flow i think

I have three suggestions, in order of cost.

The first is to get activated carbon meshes. Availble from any place that sells aquarium supplies. This will allow you to remove your dryer sheets, which allow almost no air flow. Shouldn't cost more than ten bucks at most.

The second would be to make a new carbon scrubber following this guide. https://www.rollitup.org/do-yourself/101248-best-diy-ez-walmart-carbon.html


The third would be to purchase a superior fan.

Edit: Fourth suggestion would be to add Co2 to your grow.

You definitely need to know the temp...if it really only went up 5 degrees I don't think this would have caused your problem. I'm working with a small area and have seen temps vary from lights off 58 degrees up to lights on w/ door shut 90 degrees. It has to be pretty hot and your plant really close to the light for it to dry out like that.

You typically should want the tops of your plants to be under the light just to where you can also place your hand there and not feel the extreme warmth from your lamp.
