Thats what I'm saying runoff happens when the media is 100% saturated. The amount of drainage directly affect the o2 exchange capacity.runoff doesnt mean over watering. Need a bit of patience in potting soil but thats my favorite feature. I can equal yield with so much less water and nutes.
Much much better gas exchange IMO I agree.That’s the beautiful thing about growing. Grow in a hardware bucket. Traditional plastic pots. Whatever.
personally I use fabric. Almost Impossible to overwater. Can control airflow through the root zone better. Only negative is transplanting out of them.

I cut the bastards off if the roots are tight.
pretty cheap.

Plastic posts. Used them for years. Still use sometimes. You could grow weed in my left boot if you wanted to.
Commercial facilities use them as they are reusable, super durable, easy to clean, easy to stack, and cheaper
Air pruning is a thing, plants that are in fabric pots are less prone to becoming root bound. Just my experience
Mr.G
Sure it does... only need to flush through if to much is added... not near as common with organics but yes possible... but thats just grower error.

RO with nutrients? What type of system?I got a dumb ? If i fill my 35 gal res with RO do i have to areate to keep the o2 in the water? Its covered will i still lose 02 from water if i dont move it? I quit areating cuase my ph woukd go up to almost 8. Thought it was getting too much co2 in there....or was co2 being pushed out and the ph went up?
P.s. i fucking hate my water
RO with nutrients? What type of system?
No real need to aerate unless you using bacteria or for RDWC.
There are alot of factors at play here. Alkalinity mainly. The source of Alkalinity and the acid used to adjust ph.
Yeah I wouldn't worry about it.I fill it with water, take what i need when i need it. The trash can (clean amd sani'd every refill) can sit for a week with no areation.. its straight RO water that is staged in a cold room water is 62 f can sit for a week to week and a half with no nutes i it...if anything other than RO was in there id areate for sure...i just wanted to make sure 02 wont expell from the water. It is covered and barely gets moved...oh and im in soil
They were light burned... talking about seedlings and early veg there is no need to have that much light. Flower is a different story.You have many issues here, but I am going to address the most glaring one. I know you are limited it space, but 2 45 w fluorescents is not going to do the trick, not even close- at least a 315 w cmh at the very minimum. Furthermore in low light scenarios like this, imbalances and overnuting is more of a problem than deficiencies.
Your next issue- ph of water doesnt matter- in fact peat based mediums want to go acidic, it doesn't matter how high the PH of your water is- in fact I have to add dolomite lime to my peat based medium so it doesnt sink on me halfway in to flower.
Lastly, even though your RH is pretty low, so is your temp- so it really doesnt matter. Conversely if you have high RH, its not that big of a deal if your temps are a little higher (assuming no mold or PM risk) - this is because of something called Vapor Pressure Deficit- there are charts you can find on google.
I dont know what to tell ya they were light burned... the lights were to close... its not just wattage.Light burned? He is running literally 90 total watts of fluorescent lighting. He is in going on a 3 weeks, almost a month of the plants being alive. My 2 ft fluorescents panel is exactly 90 watts. If I had 3 plants under for three weeks, they would be needing a new light- especially with no side lighting from other lights.- and I only keep then 2 to 3 inches away-no ill effects
Besides did he say he planned on blooming under different lights? I might of missed that.
My CMH- abt 15 inches
My 720ROIs- abt 14 inches
My 1000w raptor-abt 12 inches
Never had one plant light burn on me
In fact the only time I have ever seen a light burn on a plant under a fluorscent? When it grew into the bulb and was touching.
I am not getting your point about VPD. I understand too low of temps locks out things like phosphorous, or too low humidity messes with K uptake. Or running high temps because you have high humidity can be a bad idea late in flower because of molds and what not-or that vegging plants root better over 55 RH-The point I was trying to make is if your temps are a little higher, you can get away with a little higher humidity (early enough in 12/12) and in the case if this gentlemen, being a little lower in humidity wont kill him since his temps are so low.
VPD charts seem pretty damn consistent btw- i haven't found too much variation.
And measuring true leaf temp requires instruments this gentleman probably doesn't have from my understanding.
Yep. Absolutely. Let them dry out. Took me so long to learn. A little water can go a long wayyou can see the perlite (white stuff in soil), it has discoloured and even yellowed, that means the soil was staying wet for to long, watering too much, you can see the damage in a couple leaves from it, they won’t recover,
everything will be fine, just let grow and follow a wet/dry cycle..
as it dries the roots grow in search of food, roots grow = plant grows
Okay, will go take a pic, but.... try not to laugh, it is a bit embarrassing! It is our first grow... so complete newbies here and without a great set-up.
Here's the set-up:
Set-up in a closet
2 boxes stacked together with reflective surface on bottom sides and foil on top sides.
Fan added to top of box (inset) (green cardboard, directing flow down)
2 CFL lamps and a very small LED - 4 strip
Cellophane on top to try and keep humidity in.
We were actually worried the lights weren't enough. So we have 2 three way socket(s) and different bulbs coming early next week, a couple of 2700K and a couple of 6500K. The ones in there are currently 40 or 45 watt 5500K (I think).
We have been able to keep the temperature in 72-77, humidity has been a problem (20-30%), so we bought a small humidifier to go in the box. Too small to make any difference.
