First Grow - advice and tips appreciated

[Skyline7575]

Hey everyone. This is my first post here and it’s my first grow. It’s two Critical Autoflowers and it’s indoors. I’m using a 48x48x80 grow tent along with exhaust and intake fans for proper ventilation. Growing in FFOF using a Phlizon LED 3000w COB (615 actual Watts). I’m PHing my water down from 7.3 to 6.5. Today is exactly 5 weeks into the grow. I’m curious what your guys opinions and tips are on my grow so far or if i should just keep moving forward as i am. Thank you!

Looking good, I've seen people gettin er done with alot less, see how she rolls along and build on that!!

Looks Good! Are you adding CO2?? That may speed things up a bit more for ya! Oh and think about initiating the bloom before they get to tall for your tent!

Im not adding any CO2. Would that be beneficial even with temps under 80F? And these are autoflowers so I’m confused what you mean by initiate the bloom. I’m under the impression these will do that theirselves.

Co2 is only really beneficial if the environment is sealed, not so much for a tent in your case. There is no switching to bloom with an auto, you are correct.

Oh sorry, they will bloom on their own in that case, no worries!
CO2 outdoors is set around 300 to 500 ppm, while indoors can be quite low at 50 to 150 ppm. The low CO2 levels cause photosynthesis to slow down quite a bit as the plant struggles to breathe. With the proper amount of additional CO2 (500-1500ppm) your plants will receive quite a boost in vigor!! Do not exceed 1500ppm to avoid toxic levels. Your CO2 regulator will come with easy instructions, or, there are now fungus bags available that can raise CO2 levels back to optimal!! Happy growing!

Don't bother with Co2. It's not worth the trouble or expense for a small few plant grow. And if you're in a grow tent exhausting the air it's pointless anyway. You need a sealed environment like @Tormentedangel420 said. Definitely don't waste any time with those hokey Co2 bags or any DIY nonsense involving yeast.

Actually Co2 levels are higher indoors than outdoors. Background concentrations of Co2 outdoors is around 400 ppm while indoors that concentration can range from 400 - 1000 ppm

Whoa now you guys slow down and please don’t mislead somebody into thinking CO2 is a waste of time?! Yes indoor CO2 levels can increase a bit under three main situations...1 overcrowded living space with a lot of people (can increase levels to between 1000-1500 ppm), 2 Certain Air Conditioning and Natural gas heat (adds 50-100 ppm), and water logged soils trapping gas beneath your foundation. However unless the room that the tent is occupied in is also occupied by many people at all times these inflated CO2 levels simply do not occur. Add the usage of CO2 by the plants for photosynthesis and you have seriously depleted CO2 levels causing suffocation of the plants. In summary, unless you are enjoying cocktails all day under the artificial sun in your tent, you will always benefit from adding CO2!!
