I wouldn't waste the inline fan during dark hours ... it IS important to keep an oscillating fan on your plants 24/7 ... yes, feeding changes dramatically for flowering ... you will provide much less nitrogen, and heavier on your phosphate and potash ... get a good quality 'Bloom' nute, I prefer 'Fox Farm's Tiger Bloom' ... :smokin:
leave the fan on , i didn t and i payed the price , i lost a couple of oz s to moldQuote:

i leave myn on to keep the air moving.and it creates a vacumm that pulls fresh air in
i don't have mine on for the night, nor is the airpump in the DWC.
check my link in sig to check out my grow.
If you even suspect that you have a humidity problem (and it is safer to assume that you do, even if you don't, than it is to assume you don't, lol!), definitely keep exchanging air 24 hours a day. You don't need to exchange AS MUCH air, so if you have multiple exhausts (it's common to run the lighting cooling exhaust on a separate circuit from the room exhaust), sure, go ahead and kill the lighting exhaust about an hour after the lights go out (allows time for bulb and hood to cool). But leave at least minimal air exchange going.
Yes, you need bloom ferts for flowering- they have less nitrogen than your veg fert, and more phosphorous.
i think you should leave your DWC airpump on 24\7 , the roots need oxy all the time, not just when the lights are onQuote:

however, in my 3rd grow, I plan on getting some different nutes (the correct kind this time), and a better air pump
Run your air pump and room exhaust on the same circuit, set to 24/0.
Run your lights (and hood exhaust if applicable) on another circuit, on a timer set to 12/12.
what about in a dwc/WF set up where you have a drip and an airstone. I was planning on running the drip and airstone for 30 min every hour and a half at night, and 30 min on 30 min off during lighting hours. I wanted to do 15 on 15 off for daylight, and 15 on 45 min off for night, but cant find a timer with that low of settings.
a DWC res needs to be aerated 24\7, even with a drip set-up.Quote:

If you can't get your temps to a respectable level without the fan at night, you'll need to use the fan. I have no ventilation at night in my mother, veg, or flower sections unless the temp is above 70 (using an atmospheric controller). I know people say this is wrong, but I've been getting lots of good weed for years. Consider though that my humidity stays at around 30. If you have high humidity it may be a different story.Quote:
