It will stay cold on concrete.you will b good.but i hear ya on monitering yurself..thats a must.good luck bro
You are correct.. But what I am saying is that there is a better , more cost effective, way to get oxygen to the rootzone.
Do you have a "DO" meter? Can you tell me how efficiently your air pumps are working? Do you know how much oxygen is in our "air" How long does it take to raise your "DO" levels in your water?
Im my opinion... that is a terrible reason to use something.
Good luck!
Thank you and WELL SAID!BRAVO…Hey cannabeans you are definitely the brightest grower on this block for sure when it comes to oxygenation, how and why test dissolved oxygen in res water is so vitally important.
Keep in mind that the vast majority of hobby growers do not know the difference between ambient and elemental oxygen (O2) and that’s a well known fact on most hobby forums.
Most hobby growers think that (know) if they see plenty of air bubbles, that plenty elemental oxygen (O2) is guaranteed provided you have enough bubble rocks or the water falls are high enough.
Most hobby growers have no idea what a DO Meter is and they are totally unconcerned the value of having or testing DO. They don’t even care that DO can be tested with DO Test strips that cost 0$.50 per test.
MYTH - Ambient air is oxygen (O2) and plenty ambient air always insures plenty oxygen (O2). That's a water chiller salesman sales pitch, that's all.
If this were true hospitals would use electric fans and would not have oxygen (2) piped into every room in the facility. They would not need or ever use those little portable O2 bottles or O2 mask either.
Most hobby growers believe and promote sales saying that the DO Saturation is 100% dependent on using water chillers and cold res water. The water chiller salesmen continuously reinforce this their primary sales point and the DO Chart proves their point. We’ve all heard the sales pitch.
So how much elemental oxygen is the minimal safe concentration required for all the pot root balls and aerobic colonies collectively? How much oxygen (O2) does all this really need? Not talking about ambient air, talking about O2 only. The nitrogen and hydrogen is air is totally meaningless for all aerobic plants and microbes living in the res water.
This is how much oxygen – 100% DO Saturation 24/7 regardless of the res water temperature (61F – 87F). 100% DO Saturation must be sustained continuously throughout the months of growing period or watch for dead decaying roots, root rot and fungal infestations… watch every day too.
Most hobby grower’s guess and hope when it comes to maintaining minimal safe DO Saturations in res water because they never test the res water DO. Hobby growers do very excited when they discover root rot one morning and then go automatically into crises mode, brewing teas, poisons, adding H2O2 to increase the res DO and kill all the microbes and trying to accept the reality that they have had a serious low-O2 problem. And it’s way, way to late by then.
Or just watch yur leaves...lmfao...im an ol skool grower n wile i do hav digital ph/tds meter which is a must in water.a chiller is not needed.lol.its not as tech as some people make it....stick yur fucking hand n the water.would u jump n a pool at that temp??yes?then yur too warm,no?yur probably in the zone..idk what u consider hobbiest but i got lil over 800sq i use every inch.most gidgets/gadgets arent needed to make ALOT of cash..or smoke whatever floats yur boat.just learn how to read leaves in it tells u everything.they will look dehydrated if not getting enough o2..keep it simple..stupid.
This is no challenge of wits at all, this is pure horticulture science and technology for profits and fun vs. "reading the leaves" so to speak, that's all this is. Great looking sticks, what do you sell 1/2 oz. of those buds for?View attachment 693899 View attachment 693901 This turned into somekind of battle or wits or something?lmao.dude just askd if his roots lookd good bro.no d.o.'s Jhenry but yes i fully understand them..42 branches 1 plant(3wk veg/clone)...i think i kno wtf im talking bout....like i already said we can compare pics??if u aint got none its cause it never happned.....
yur basicaly saying samething as i am if u read what i wrote..i use 300gal pumps(4outlets)..thats 75gph to each tote.it takes 7gal to fill a 10gal tote full over netcup like ol boy mike...im throwing 4-5gal instead of 7 to totaly full.dont u think 75gph will oxygenate 4gal better then 7??lol.if yur plants arent getting enough o2 it will b painfully obvious..they will look dehydrated.i kno i wouldnt need a meter for this.lowering water levels helps me n multiple ways,ends up more o2 cuz same size pump less volume of water,my roots harden which is obvious will aid with rot,and i use less nutes cause my nutes r EXPENSIVE...Plenty dissolved oxygen means insuring 100% DO Saturation 24/7 every day of the several months growing cycle whether the water temperature is 65F or 86F.
That’s is what prevents Rhizome and microbial suffocation caused by low oxygen in res water.
Preventing a low O2 problem is better than waiting, worry and watching pot roots for the low oxygen crisis, suffocation and the sundry pantheon of emergency treatments
yur basicaly saying samething as i am if u read what i wrote..QUOTE]
Yep, your right. Hobby growing is certainly not rocket science or anything close to it. More technical pro growing may be more aligned to horticulture science 401-B, that’s all… more applicable to the large scale commercial medical market pro-growers that grow strictly for high profits and highest quality yield vs. the average hobby grower. About farming for profit and making money vs. growing for fun and getting loaded.
Like I said, your sticks look good, “…what do you sell 1/2 oz. of those buds for?”
