Lol, Some people are happy enough with anything green that has some form of thc on it. If you want some smoke and you dont care then do as said, chuck some seeds at some dirt, piss in that general direction and you are set to harvest pounds.
I mean if you add ONE more plant to double your harvest you must only be growing one plant? A small pc fan and a block of dry ice for one plant is probably good ratio! If you have 4 plants, adding one more will only increase the yield by 25%. So if you have 4 plants, and add co2 for a 20% increase (not with dry ice, but proper co2) You are getting almost a whole extra plant worth of product, without needing to add another pot, losing much space in the room, you dont need to worry about it being male or dying.
Dont blow smoke into your plants or the room, the contaminants in the smoke will absolutely cause the plant to not grow as fast as it could, as the plant will close its stomata which slows everything down.
Hydroponics is about creating the perfect indoor environment. It should be BETTER in your properly set up grow room than outside. I think some of these newbies with 16 posts think hydro is just a way to grow without your neighbors seeing...Its not..Why use r/o water, ph meters, tds meters, why grow in neutral medium rather than soil?
Control. We want to control EXACTLY how much water gets to the roots, when it gets there, the contents of that water including dissolved oxygen and the temps airflow co2 levels etc. We want the plant to spend every single bit of energy just growing, not stressing looking for adequate light, nutes, co2 etc. For those who ARENT bio students, the plant uses light and co2 to break down nutrients into sugar. It then uses the sugar to grow. (put simply). Just like if humans breathe "oxygen" we feel more energetic, when plants breathe "co2" they also become more energetic.
Of course you never want pure oxygen or pure co2...
So if your whole point was to say "plants will grow without additional co2" then awesome, thank you ill keep that in mind. However the OP asked how beneficial dry ice wold be. The answer? well just be careful with a fan blowing straight over the ice to your plants. They dont like cold air blowing directly on them. Blow the dry ice up at the lamp, if you aim it right it will pool in the reflector and fall slowly being heavier than air.
SUPPLEMENTAL co2 WILL HELP. Just don't blow it out your window with your exhaust fan. Maybe get the dry ice going, and a few homemade yeast co2 generators..Just trickling out a little bit extra.
Sorry to jump down your throat
Paulorustobernardo but if you go around telling everyone plants dont care about their environment you are going to utterly DECIMATE the hard work experienced growers put in to teaching newbs the right way to do things. Its an hour worth of effort buying the ice and putting it in the room, you will get more than an hours worth of extra weed out of it, so long as there is nutes to uptake, light to photosynthesize, and the plant isnt stressed.
Just imagine if someone came to your threads where you ask how far the light should be from the top of the plant and they said "put it all the way up to the roof, you dont need it close! Ive seen plants grow under moonlight!". You dont want stretchy crappy plants, you dont want burnt plants. So you would want to hear how to get the BEST result from someone who has been a member for more than 2 weeks, and has PERSONALLY set the levels of their light so many times they could do yours with their eyes closed. And there are people here who HAVE done co2/ no co2 comparisons, and it is worth it. Perhaps not worth buying a ppm controller and gas tanks for a few plants, but dry ice for one plant, or the tanks for a room and theres significant increase in weight, as well as decreased wasted THC as theres is less oxygen ppm there's also less oxidization of thc. Ive worked at a cold storage plant where they fill the rooms with inert gasses and apples wont go off, but arent frozen..just cool and no oxygen. Same thing, but instead of the first trichromes oxidizing before the last ones are developed, you would hope with proper co2 levels maintained, more of the first lot will still be in usable condition!
Stoned as! Dunno how long this post is, dunno what Ive written...hitting the post button anyway!
