gorge cervantes says no intake\exhaust?????????

sealed grow rooms dont work because there is no change in the actual air. while the plant respires 02 the room will eventually fill up with o2 and stoping photosynthesis because there would be so much pressure from the built up 02 the the c02 wont be delivered. thats why when commerical grows employ proper c02 they vent every 15 then seal it again.

I grew in a sealed environment for a couple years with great results. My yeilds were always plenty with fat dank crystal buds.

it works well
i know someone that runs 4 1000s and a sealed
room with co2 just air runnig threw the lines fresh air
from outside threw the tubes threw the lights
then outside huge buds

 

[bossman88188]

well that all helped thanks for everyone input.

you can grow in a sealed environment. i have seen huge grows doing it. check "urban growers" vids on youtube. somewhere in there he visits a huge one. i think this is pretty advanced though.

jorge is still a tool.

I bought Garden Knowm's dvd's ive always been a little iffy about Gorge

This is absolutly untrue.

CO 2 is taken in through millions of microscopic openings located on the undersides of the leaves known as stomata. It is here that carbon dioxide is absorbed by the plant and taken within the interior of the plant in order to be combined with chloroplast and water to form Adenosine Triphosphate (ATP) the major source of usable chemical energy in metabolism. ATP is a compound that can be transported and broken down to be used for energy needed for development.

O2 is expelled in a completely different manner un related to co2 intake. Further more no matter how well sealed a room is the gasses contained within will still dissipate. Since you are supplementing co2 at a higher rate than the plant expels (respire refers to both intake and output) o2 there is no issue here.

actually I'said i believe ul find its more than just a related process..its part of the same process..photosynthesis. the plant 'breathes' in CO2 and 'breathes' out Oxygen. Kinda like humans but he opposite way aroundi think thats right..im hiigh tho

Ghost420..as far as i understand although the pressure in the room would go up, in theory anyway..if it was actually airtight, until the rooms pressure is higher than the pressure in the CO2 can the CO2 can easily move out into the growroom.

Yes, they are related as in part of the same process. Unlike in the human body, where one central organ is responsible for both actions, a plant uses two very different parts to do this. My reference to respire was to say that plant didn't "breath in and out of the same hole" Thus the build up of O2 is not an issue. The only problem O2 can cause is that it can "collect" on the underside of the leaves covering the stomata. That can block the stomata from taking in CO2. A simple ocilating fan will prevent this.

This theory is flawed IMO. It implies that if a plant was kept in an ideal, 100% sealed and impermeable environment (which is next to impossible in a non scientific realm) where CO2 is injected at the exact same rate as O2 is expelled, that the pressure would build exponentially. The plant is not capable of pressurizing, or compressing, the gases. Therefore there is no pressure difference inside the growing environment. Either way it is next to impossible to seal a grow room to the point at which gasses will not dissipate.

My problem has been 'off-gassing' in an sealed environment!

off gassing what?

i think he means farts lol

It is so nice to see competent growers bring Cervantes down a notch. Maybe it is just his dumb image that makes me mad, because I hate people like that, who just need a damn haircut, but I can't stand the little cult that seems to have popped up around him.
Sure, maybe his grow advice is sound, but it's nothing special. I'd rather come glean some info from articulate growers like Fdd, VV, or Stinkbud, who don't come to the table thinking they are infallible. I'll take a collection of experience like RIU over Jorge's boring conventional methods any day.

What in your environment has been off gassing? Did you build a new structure? Is the location it is in newer construction?

Anything containing DBP (makes pvc soft), spray adhesive, pvc glue etc. I lost three consecutive grows before figuring it out
Symptoms are as follows:
Starts with a general MG def. from the bottom up, next an overall yellowing i.e. nitrogen def. next stunted growth. Looks like the plant can't handle light anymore and the leafs start dying back.
Keep in mind that we are talking sealed environment here, toxic levels of gasses can easily build up, especially at higher temps. It is fucking sick!
There has been a big issue with Hydro-Huts that have the white liner on the inside.
Anyway, now you guys can make fart jokes again Hope it never happens to you!

i agree that cervantes is a tool.and probably hasnt grown himself for years.
his bible was full of how the equipment works then actually growing.
i still read every issue of high times and if i learn something new then bonus.
as i have said before i want to learn anything i can.
p.s. without being a dick like my weedless post at loudblunt.
he set me straight well deserved.

 

[bossman88188]

its all good skill i am not usually so easily offended. that noobooty shit was funny

 

[bossman88188]

teah i hit 200 im a pothead. i can die happy now.lol

 

[LoudBlunts]

lol congrats!!!

it looks like they are absorbing the glues. i have had that same issue from too much duct tape.
i read somewhere that cannabis will absorb (for lack of a better descreption) from anything around it.
thats why they supposedly planted it at chernabel after it blew.
anyone else herd that.
