I am on my second grow and need sone criticism. I have 15 autos growing; Blue Cheese, Jack H, and Super Lemon Haze. All are ILGM seeds. I am on week 6 of flower stage using ILGM nutrient line up. I have 2 XL Co2 bags and average a C02 PPM of 1400 up to now. Lights were running about 800 to 900 on the meter. Soil PH has been 6.5, and I am using HF soil. Feedings are PH’d around 6.3 for all watering and feeding. Temp has averaged about 78 to 79 degrees but I have had days that have reached 81deg. Humidity has been 50 -60% . I noticed alot of yellowing now at week 6 of flower, and added 3ml / gallon of calmag during each watering. I have also used 1 tsp of Mychoryza each watering. I would love some feed back if possible, and have attached some pics.
Nice grow @Creaturefiend! I’m no pro, but I did see some cal-mag issues on a few leaves. You addressed that already. Other than that from what I can see just some painted nails (nute max). Very pretty colas.
O, forgot the criticism. Black nets are better. lol
Criticism - Co2 is useless unless you are in a completely sealed environment. Cannabis plants require minimum 400 ppm of Co2. Our natural atmosphere is about 425 so you do not need to add any.
Commercial grows and/or home grows where folks have a sealed environment can benefit from the increased Co2 as it allows them to really push the envelope for more light, more nutrients and can take higher temps without canoeing.
and here is info related to improper/high amounts in relation to us hoomans.
Researchers have observed CO2 levels over 1,000ppm in poorly ventilated bedrooms and now say acute exposure to this could negatively affect human health.
and another
To minimize the risk of airborne transmission of viruses, Indoor CO2 levels should be as close as possible in all areas to 400 ppm. If the threshold is exceeded, it is recommended to leave the room and to renew the air. @Creaturefiend
I sit with my girls as it calms me. While doing so, I exhale into the tent regularly. The big benefit of “talking” to your plants is actually the exhalation of Co2. I have passed out once from blowing too much at one sitting. Haha!!
Yes. Be vary careful. A former member of this forum lost a friend due to CO2 poisoning.
For CO2 to be effective you will need, besides very intense lighting and a sealed room to push the partial pressures up. Generally the biggest benefit is during veg. To accomplish this you will have to up your game on environmental control: run an AC split and a dehumidifier to manage high temps and RH. If running a closed system for any length of time you will need to pump O to the roots to avoid suffocating the plant (roots need O). Usually growers with CO2 run hydro to push both air to the roots and insane salt levels (2,000 ppm plus).
My buddy also almost died from this. Had a co2 setup in his basement and it was supposed to be a sealed environment but was leaking into the actual living quarters of the house and they didnt know until he had to go tohe hospital one day and they said another week with exposure at his levels and he would be dead. If your gonna go this route make sure you have alarms and monitors in your growing space and house to avoid any issues
@MidwestGuy@BigCat420 , sorry for the delayed reply. I had to go and weather out that hurricane in FL to make sure the in-laws were okay.
Thank you for the C02 warnings. That is a scary thought and sad outcomes. You may have just saved the life of a newbie. Sounds like the risks are not worth it.
I also want to say that this is a great forum and a great group for support with the growing journey. Much appreciated
I will be posting some more pictures today. Went away for 4 days and the changes in the plants surprised me. I opened the tent and my wife immediately came down to my grow room saying she could smell it on our ground floor and upstairs rooms
,
whichever has the amber heads is real close. Great job across the board.
