how do you tackle your dissolved oxygen situation? currently I’m just using an air stone, i’ve heard it doesnt do much more than mix the nutrients around and can be hazardous in the effort of keeping pH stable, not sure if thats just speculation or the truth but it seems to be a cheap easy option for nowAll this means nothing if people dont fix their system. If you have enough light leaks, or not enough oxygen for your bacteria, the root rot will destroy it. It uses photosynthesis to reproduce unlike your bacteria. . . so yea, you need to have a good hydrosystem first and foremost. I get confused as to whos who and runs what, i just reply lol. . dont really scroll up unless needed.
MAY THE FORCE BE WITH YOU
So, airstones do a few things. They assist in breaking up the surface of water, turning it over, which the more agitation you have, the more "organic" oxygen acquisition you'll see in the water. However, dissolved oxygen is partially affected by temperature, and since air stones add heat to the water, it's a counterproductive solution. You'll see pH swings as a result of the increased CO2 introduced to the solution since the air pumps will just pump in ambient air which a normal residential room runs around 300-450 ppm CO2. That will raise pH. That's why I personally do not run air pumps -- heat + CO2 + they clog easily + pumps are fuckin noisy.how do you tackle your dissolved oxygen situation? currently I’m just using an air stone, i’ve heard it doesnt do much more than mix the nutrients around and can be hazardous in the effort of keeping pH stable, not sure if thats just speculation or the truth but it seems to be a cheap easy option for now
do you use that? or do you solely use Z7?i would go with southern AG instead of hydroguard. The concentration product is better than a product that has 1000/L of water. lol!
So air-stones dont really mix the nutrients. There will be gaps where nutrients sit still, thats when roots become long and stringy as they search for them.how do you tackle your dissolved oxygen situation? currently I’m just using an air stone, i’ve heard it doesnt do much more than mix the nutrients around and can be hazardous in the effort of keeping pH stable, not sure if thats just speculation or the truth but it seems to be a cheap easy option for now

h2o2 is a better option for me. I run sterile, don't struggle with keep good bacteria strong enough to combat bad bacteria, and have more DO than a heavily aerated system. Also save money as hydroguard and the like are twice as expensive as a gallon of 34% h2o2 at a quarter of the volume.
ah you're reading too deep.what is the environment around your system?
for instance my shed sits in my backyard, just an aluminum shed propped up on cinderblocks insulated with 2-1/2” r tech boards on the inside.
so i believe it might be somewhat harder to achieve a sterile system with my set up, the water flows in through the ground of the shed when it rains air circulates freely from the outside etc
i guess im asking is yours completely like lab grade sterilized or what level of cleanliness do
you adhere to?
this is fundamental. if using high concentration of O2 like in h2o2, it's so fuckin corrosive you eliminate any possibility of anything unsavory growing -- including roots if you're running too high of concentrations.eliminate all light leaks and your golden.

h2o2 is not to be fucked with. period.
it is a seriously corrosive chemical and should be treated with utmost respect. any sterile grower will tell you stories of the burns that shit will leave.
it's hard af to explain to an employer, a lover, a friend, why you have white spots on your skin after you fuck up handling it. it hurts, seriously, and it's not like an acid or base where you can neutralize the burn easily. even flushing with water doesn't cut it enough to prevent damage.
vinegar is an incredibly weak acid. you need phosphoric acid or sulfiric acid for any kind of stability.I can't even find the stuff at a decent percentage anymore, and the price on anything is also to high. Is vinegar an alternative? I'm making my own now for pH down and cleaning purposes, pretty east to make(I think).
Thanks, I'm not very knowledgeable on the subject. I thought that h2o2 was being used for cleaning/algae prevention in the conversation before. I was wondering if vinegar good in that situation (mainly the algae prevention, I already use it for cleaning and it works fine).vinegar is an incredibly weak acid. you need phosphoric acid or sulfiric acid for any kind of stability.
I agree. At OP cant you put black plastic(or anything light can't get through), over the lid and cut X's where the holes for the pots are?light penetrates through the yellow lids and also through the net pot that is empty.
hes not entirely empty hes got about 3 inches of hydroton at the bottom, but definitely see your pointlight penetrates through the yellow lids and also through the net pot that is empty so no wonder that algae has started again. Now you gotta do the whole thing again and bleach, rub it with h2o2 and than tap water everything down few times. Sterlite equipment is a must.
still light hits it through the opening areas and through the yellow lid. At this stage of the plants lifes, the leaves aren't big enough to cover the lid.hes not entirely empty hes got about 3 inches of hydroton at the bottom, but definitely see your point
currently im just worried what i can paint it with that wont harm the plant, and will also be quick and easy as this is their only holding spaceI agree. At OP cant you put black (or anything light can't get through), plastic over the lid and cut X's where the holes for the pots are?
Also at OP, are you letting your water sit out for several days before using and/or making sure that once you lower the pH, that it does not rise afterwards?
have any good ideas on the type of paint to buy?still light hits it through the opening areas and through the yellow lid. At this stage of the plants lifes, the leaves aren't big enough to cover the lid.
