so if you are tring to kill bugs dont fall asleep in the room with your plants and yes i wouldnt do this if your plants arent in there own room. use common sence!! if i read the osha info correctly 30,000 ppm is ok for under 10min. none of us should ever get close to 30,000ppm.

OSHA limits on Carbon Dioxide Exposure: The U.S. Department of Labor Occupational Safety & Health Administration, OSHA, has set Permissible Exposure Limits for Carbon Dioxide in workplace atmospheres at 10,000 ppm of CO2 measured as a Time Weighted Average (TWA) level of exposure and OSHA has...

just follow the rules. Air, Water, Light Air temp+ 75-78degrees (the distance of the light will make it right) keep humidy elevated 80-90% for 3-5days with a dome. if u can 90% first 2days than drop 5%aday thereafter Water (medium)+ 80-83degrees for rapid rooter, keep the medium moist, not...

thanks sparkabowl.. id say cut them and get the next ones going. i dont think they'll get much bigger. you can get a microscope from radioshack for ten bucks, cut a small leaf off and look at the trichs but most of the time when 90percent of the hairs are brown i cut them down

yes need to do treatments every few days cause the eggs will not be harmed by co2.. no pest strips are wonderful

thanks guys. the no pest strips are great and so is 10,000ppm co2, but since i picked up the nps and used four in a 650sqft room i havent had any bugs. now i have two strips out and i figure their not fresh but just prevention. next bugs i see i buy new nps. i think nps are the best. way better...

30,000ppm is not safe but shouldnt kill either and 30,000ppm is 3% so 8% probably could kill though its lack of o2 not co2 that kills imo co2 is way better than spraying your plants with shit. i like nps also

on my second try with dwc. still having some problems though going slightly better than the first try. 14 days into flower now. im hoping the shorter ones will catch up. im worried if i try to move them the damage to the roots will more than the benefit of having the shorter ones in the middle...

get a cheap indoor outdoor thermometer for like ten bucks that shows humidy too. and put it in under the dome with the outdoor temp probe in a empty rapid rooter. make sure the probe is all the way down in the rapid rooter. this way you can have the air temp under the dome and humidy and medium...

ahahha grannies tank. lmao thinking about injecting co2 and o2 at the same time.. it always cracks me up when ppl say your going to die from running co2

ahhhahahhahahahaha

thank you stalwart

13 days into flower. some burning i think either cause of heat, lights or nutes. or mayb alittle of all. 900ppm. ph stable:)

these pics were from the last and first go at dwc

mine are 13days into flower and are at 900ppm and are burning alittle. i think its from the nutes but could be the light maybe im not sure

im deciding wether to take off a few more of the lower branches. im 13 days into flower. any ideas?? Thanks and fyi some of the pictures are from the last round. hoping this go at it is much better hindu kush :)

i know hps is supposed to be better but i just havent seen it. ive used both and the only difference i see is stems elongate more under a hps. i like to switch the lights every week or two so the plants get both. the 'eye blue' bulb is worth the money imo. the plants always seem healthier...

i like the combo of the two bulbs. the area is just under 3x6 in a 630sq' room. the generator is a 'greenair' and the controller is the 'cap4' im about to scrap the generator i have for one with electronic ignition. i have to talk to greenair and see if the older one i have can be upgraded.

the ones under the hps arent as perky, im guessin its only from the heat or the mh is just better. Eye blue and super hps

13 days into flower. been using co2 with fan on/off. temps on 80/ off 90.. how do ya post pics
