It was an easy harvest as the colas developed nicely. Hardly any popcorn nugs and very little sugar leaves. If the weather had allowed it, I think she could have grown even bigger, but I'm more than happy with the outcome!

Day 29 Flowering: Hi all. As another week passes these exotic ladies are impressing the hell out of me. They have all really put some energy into forming long colas with really bulky little budlets along their whole stems. Herz o.g is by far the chunkier of the three but not by a big margin at all. her crown is forming nicely from above and I can clearly see her future potential colas. She looks a very nice colour of green on her leaves whichnis down to the Megacrop and its amazing chlorophyll building properties. This will help to really power those fan leaves to pump the nutrients and essentials to the forming buds I am now trying to stress her as little as possible to allow her to keep her focus on that alone and not dealing with uneeded stresses. Strawberry Cola is beginning to build some nice stacks too. Her stretch helped to keep her in the canopy but she is at present overshadowed by a huge mimosa Lemon due harvesting. it has stolen some of her light over the past week or so but this will be corrected as I begin harvesting the other strains running shortly. Monster mash isnrhe biggest surprise... she came up out of nowhere over the last few days. She now towers the whole grow rooms strains. Her cola lengths are looking very positive with the nodes reaching to low in the canopy too. She will also benefit from a move around as I harvest the other strains. She will get a prime position to keep those colas stacking up long. They have all had a defol at day 21 and the air can get around their frames really easily to keep the chance of mould right down. So far so good and very happy days ahead . Be safe and well growmies.

This week went by quickly. They're doin their Pre-Flower stretch and getting big quickly!! I added my Pre-Flower mix to them this week. My Nutrient Pre-Flower Mix consists of H20, Coconut, Bananas, Pineapple, Sweet Potatoes, Kelp, Alfalfa Meal, All Organic Non-Pasturized Whole Milk, Epsom Salts, Black Strap Molasses, and L.A.B. or Lactic Acid Bacteria. First, I boiled the coconut, pineapple, sweet potatoes, the bananas, and left the skins on as well except the coconut of course! That I had to split in half and make sure to keep the water inside to add to the boil. After boiling everything I then let it cool and then added it to a blender to blend little by little. After blending I left separate and placed into the fridge. Then I took 1 Tbsp of Alfalfa Meal and 2 Tbsp of Kelp, 500mL of the milk, 2 Tbsp of Epsom Salts, and mixed them in a 750 mL bottle. Then I took 1L of the mix and added 2 Tbsp of L.A.B. and 2 Tbsp of Black Strap Molasses and then shook the bottle well! Then I took the 750mL bottle and the 1L bottle and fed that to the plants adding 250 mL of pH H2O to the plant as well to flush the ingredients all into the plant with the H20. I wanted to also note that I choose to slowly defoliate so that the plant doesn't go into shock and also fan leaves collect light in all spectrums so taking too many off at a time could hurt or slow the growth of your plant! The amount of light your plant takes in daily is called DLI or Daily Light Index. Overall, they're really growing and have a ton of bud sites developing! I'm excited to see the growth weekly and their colors!

3 seeds from barneys farm : zkittlez Og auto. Diary : Day 1: I dug a pit and cleaned my dirt with metal grid and a wheelbarrow & Installed the greenhouse. Day 2 : I rotated my dirt and added universal soil. 4 x 70l to area of 6m2 . I also planted seeds in universal soil without sprouting first. Day 3 : I gave water and checked for sprouts. Bought moist meter and dripping hose. Installed those and making the greenhouse more moisty now. Putted seeds in small sprout basket for now. Feeling : Verry happy for my first time. Lots to learn.. . Excited

🌱 Wieder mal einen schönen Sonntag & zweiten Advent für die, die es betrifft 😊 🌿 Wochenupdate Die Woche war wieder bisschen was los… leider =D Ich versuche wieder alles so transparent wie möglich zu machen 😊 Zu Beginn habe ich meine Lösung wie gewohnt manuell mit hochwertigen Apera-Messinstrumenten kontrolliert angemischt und behandelt. Das lief auch immer perfekt, bis es leicht überhand genommen hat 😅 Ich habe locker 7-mal am Tag gemessen und dementsprechend anschließend gereinigt… Nach ein wenig Überlegen habe ich mich dann schließlich doch für einen Bluelab Guardian entschieden. Anfangs wollte ich nicht so viel in reinen Komfort investieren, aber mir persönlich wurde es einfach zu viel, weil ich zu oft wissen möchte, was los ist =D Letzte Woche hatte ich ja bereits erwähnt, dass ich den Stretch-Peak anhand der EC- und pH-Kurven bestimmen konnte. Das lief schon alles über den Bluelab. Da ich wirklich gerne datenbasierte Entscheidungen treffe, habe ich ab diesem Moment weiter fleißig runtertrainiert und die Werte beobachtet um den richtigen Zeitpunkt zum sortieren zu erwischen . Der Trend war dann aber erst mal, dass sie einfach wie verrückt weiterziehen 😄 Am 4. Tag bei diesem Messverhalten wäre es fast passiert… Der Uptake hat über eine Dunkelphase so dermaßen zugenommen, dass ich es mir nicht mehr erklären konnte (Peak-Messung × 2,5). Fakt war aber: Das Reservoir war von den Werten her wirklich in einen kritischen Bereich gerutscht und ich wollte das ändern. Warum das so war, dachte ich mir: kann ich auch später klären… schließlich haben die Ladys Hunger =D Also habe ich wie immer 30 L Top-Up berechnet, gemischt und auf etwa 4,30 mS/cm eingestellt, damit ich die niedrigen RESS-Werte wieder nach oben bekomme. Zum Glück habe ich auch meine Momente, man mag’s nicht glauben 😄 Ich habe random beim Abpumpen mal den Drain gemessen, weil es mir keine Ruhe gelassen hat – und siehe da: 1,9 mS/cm. Die Sonde hatte sich über die Wochen ordentlich in einen Wurzelballen geschoben und dadurch zwar konstante Werte geliefert, aber eben in einer Wurzel-Biozone und nicht im freien Draftwasser. Das klingt erst mal nicht dramatisch , aber wenn mir das nicht aufgefallen wäre, hätten die Damen rund 24 h in einem hochtoxischen Bereich gestanden… Das wären sicher ein Ordentlicher stepback gewesen... Und natürlich passiert das Ganze in einer Phase, in der ich ihnen so wenig Stress wie möglich machen möchte 😄 Ich habe jetzt aus grobem Filterschwamm kleine „Hüllen“ gebaut, die aktuell ihren Dienst tun und die Wurzeln fernhalten. Drain-Messen ist ab jetzt auf jeden Fall SOP 😄 Da der Guardian erst während des Runs eingezogen ist, konnte ich ihn leider nicht ordentlich verbauen.. 🌿 Pflanzenstatus & Training Zur Sicherheit gehe ich wieder Back to Basics und trainiere so lange weiter, bis der Rebound-Stretch sichtbar nachlässt 😊 Das sollte jetzt die Tage geschehen. Den nächsten Run gestalte ich hier definitiv anders 😄 Ich brauch doch meine Werte fürs Timing… Anschließend nur noch die Meshes bestücken, langsam am Klima schrauben – und wachsen lassen 😊 ⚙️ System Bis auf die Panne mit der Sonde läuft das System nach wie vor perfekt. Am Vorgehen mit berechneten, gezielten Lösungen hat sich nichts geändert 😊 800 PPFD 1,0 kPa VPD 700–800 ppm CO₂ im Durchschnitt 💚 Special Mention Da geht auf jeden Fall was 😄 Ich glaube, an dem Punkt kann man echt davon sprechen, dass sie durch ist. Sie ist nicht ganz so gut entwickelt wie ihre Schwestern – aber trotzdem eine sehr vitale Pflanze, die sich echt zurückgekämpft hat 😄💚 Danke fürs Lesen und eine schöne Woche euch 😊!

Day 64 - Starting week 10 today and not much happening. I didn’t even take her out of the tent, just left her in, tucked some leaves and got updated pics. Looks like she’s really starting to bud up nicely now. Day 65 - She’s definitely getting pretty cramped in the tent but not a whole lot I can do about it. Doing what I can to keep all the sites exposed and went and cut a couple lower limbs off that aren’t getting much light. Also gave her 2 gallons of pH’d water and cal-mag today. I’m giving her about 2 gallons every two days, she’s drinking a ton. Next watering, I’ll be giving her a dose of the technaflora nutes. Day 67 - The pot was dry already today so gave her a feeding of nutes today and following their schedule of feed, water, water feed so next watering will be plain pH’d water. Did a pretty heavy defoliation as well as removing a bunch of lower growth. This will probably be the only time I do this to her and will just removed dying or dead leaves from here on out, I’m just hoping I didn’t over do it but I supposed we’ll see how she does the next few days. Day 68 - All seems good and chugging along nicely after the heavy defoliation and somewhat lollipopping yesterday. Didn’t even take her out of the tent, just tucked a couple leaves that are trying to stand up and block the light. Day 69 - Right in cue, she was ready for water today so she got two gallons with cal-mag pH’d to 6.7. Looks like she’s finally stopped stretching at 27.2 inches tall and hopefully now she’ll start beefing up on the buds. Day 70 - The end of week 10 and she’s still got a ways to go and gonna be way past the 9 weeks they’re “supposed” to take but I always expect things to go longer but this will most likely be a 15-16 week harvest. Other than that, I didn’t do anything with her today but she’s definitely going to be needing more water tomorrow.

Day 79, 28th of November 2020: Hi there! Here we go let's say half way. Plants are pretty these Original Sensible Seeds genetics are fantastic! The 2 OG and the Runtz Gum is very strechy. Black Ghost is pretty shorter bushier plant. Runtz Gum and Do-Si-Dos OG approx the same height Do-Si-Dos OG is taller a bit. Wedding Gelato is really cool little, bushy anf nice buds forming not problem with her all she is quiet. Do-Si-Dos OG has some deficiency and leaf gets dry but nothing very serious..... Fertilization is still the same every second day with the rationand mixture above stated. The lamp is on 11.15 min and off 12.45 min. Last week was 15 min longer light cycle.... So every week 15 min shorter light cycle until the 5th week. So far -45 min. It switches on at 6 am and off at 17.15 pm.

Parfait elle se comporte bien les bourgeons gonfles énormément. Une odeur fruité se dégage de la tente.Les engrais bio RQS organic sont excellents elles font un super travail sans excès ni de carence. Rajout de guano au dessus du terreau pour l'explosion floral ☠️☠️ a bientôt pour plus d'informations.

Transplanted the ladies this week! Moved them into a 4 gallon pot, I plan on letting them get settled and flipping to flower soon. Temps were good this week, RH was steady at about 60%. No big surprises with the transplant, however it did take them a day or two longer than my typical recovery time.

The plant is developing well despite the high temperature. During the week the weather got better, the plant is growing well.

8/15 Yesterday the girls finally got some sun. They're flowering. Like crazy. I do need to do an application of BT once this rain stops. It just started up again. Went back over and things were dry. I decided to hold off watering until tomorrow when I feed. 8/16 Watered the 50 2 gallons, 10 1 gallon, and the rest about 1.5 gallons. I fed a pint to the ten, 2.5 pints to the 30 and 2.5 pints to the FIMMed bluecheese that looked hungry. This way I can tell if they can handle larger doses. I'd like to keep it as small and simple as possible. Gave me a fright this morning when a sheriff pulled in while I was feeding. He was on his way to a neighbors but it looked like he was just admiring things lol. I'm all legals there's no problem there. I put off spraying BT last night because dad had a couple ppl drinking and I didnt want to interact with them. Plus it was to early. The sun hadn't crested the barn yet. At least now u know what time to go spray. I'm finding some lady bugs and I killed my FIRST aphid of the season. I still have caterpillar holes in some leaves though so I might as well hit them with the BT (even though I actively hunt them). No one ever said growing cannabis is easy. Oh and my soil must be BANGING because I found some mushrooms growing in it and like a mycelium web which is awesome. 8/17 This was a quick morning due to an upcoming doctor's appointment. Removed some grass that had grown on the tar from spilt soil as it had diseases on it. I don't want that spreading to my plants. I have one blueberry cheese that I FIMed with four cola's that doesn't have as many leaves and has dropped a few leaves but looking at ot from the other side it doesnt look as open. I know that these girls are transitioning and this is the time I lose leaves. However some plants still seem totally green with no problems despite flowering. I'm wondering if it's a specific phenome thing. I also noticed that the caterpillars are still there and this morning would've been a great time to apply BT but I didn't have time and since I upped the feed I didnt want to do two things at once and have a problem and not know what it is. 8/18 Rained overnight. Plants were soaked. It's not raining now. Plants are definitely overwatered. I'm losing a few more leaves that are yellowing on the bottom interior of a couple plants. Some of it could be from the transition to flower ir the large amount of rain we've been getting. At least my drainage is really good. I need to pull the fence out and co soder cutting a pallet I. Half to better utilize space. I know I say this stuff all the time and I'm not sure it NEEDS to be done. What DOES need to be done sooner rather than later is to apply BT. I can see the damage from them. It's not bad but I want to avoid botrytis as much as possible so those pillars have got to go. Otherwise I've never had plants this healthy and it's been a real ahotty season. Boy those 10th planet's are all mice and green and healthy looking. I'm really looking forward to flowering these strains and see what they can do. I'm already greatly impressed with what I've experienced so far. UPDATE: Wasn't raining earlier then it Rained off and on but just a light steady rain that plants love but it's 3:30 now and it's pouring. Guess I won't be applying BT tonight. We need some sunshine but unfortunately I can't control the weather. Just sitting here thinking I was wondering about using Plant Doctor preventatively just due to the steady rain but I noticed mushrooms growing in my soil and since I haven't not9ced any type of fungal problem I'll revisit that idea another time. Polycarbonate roof or even some form clear plastic and a rough frame of pvc or extra lumber. Theoretically I believe I could move them all indoors for a little bit if need be but that would he a huge pain in the ass. Honestly I've got great drainage and my watering seems pretty good so I might be alright doing nothing. We shall see knock on wood. 8/19 Plants were soaked this A.M. I took a video and uploaded it (which takes forever). It's sunny though today and after the sun comes out after a period of rain the plants grow like crazy. Everything is flowering nicely. I think I can go to the end of October. I talked to a lady today that said she'd already harvested some of her peanut butter breath clones. It's my buddies mom and if you look back at one of my diaries NY mendo breath was done in September. These girls have a ways to go but the are explosively flowering which is good. It's easy to tell which strain is which. Pheno's vary but the flowers on the plants are easy to distinguish from one another. I've also never had plants stay this healthy green this long! Previously I'd have multiple pests, wpm and maybe septoria at this point. I think I've upped my game. Knock on wood. My worst problem now is worrying when to spray BT for the miner caterpillar problem. I have wasps, lady bugs and a shit ton of birds from the 3 bird feeders. I see them dart in and out of my cage. Chances are I'll spray BT tonight and take some pictures if it's nice out. 8/20 The sun is finally out. Bags are still heavy. Looks like it Rained again. I found caterpillar shit so I REALLY need to get that BT applied. I also saw minor damage to a budsite on a low hanging branch. Looks like those fucking earwigs bur I'm probably being paranoid. I also had to remove the rope that I was using to support "the big cheese" because with all this wind and rain it "rubbed" against the stem and caused an injury. I don't need that now anyway with the trellis up. Bids are developing rapidly and stacking up nicely. I have a couple plants that aren't as green as the others bit it may be do to all the rain we've been getting. I think I need to increase the volume of liquid i give my plants when I feed. Next feed I'll be doing at LEAST a quart. Due to my w8fes illness I haven't been able to spend as much time there as I should. No fungal stuff "YET". I have seen some leaves that show the plants have been over watered. Drainage is good though. I forgot to upload the video from this morning and it's uploading super slow so I'm gonna have to upload it tomorrow 8/21 Awesome. Went to town and left without going to my doctors appointment. Good job man. 👏 ANYWAY....My phone was dead when I went to town so I coukd only upload one video. I'll have to do the others later. I mixed up a batch of bt 1 tablespoon with half gallon of water (as that's what this hand mister holds. I went around the cage and sprayed every angle. Then I went to each individual plant and sprayed while spreaking the branches to make sure I got the interior. I used almost the entire half gallon so I'm hoping this will help. Bags were heavy but doesn't take them long to dry out. I'm wondering if the yellowing that is moving up (on the small purple punch and the one in the tote) is because they need more nutes, they're transitioning to flower and really stacking up or because they've been over watered with all this rain. Opinions are more than welcome. I'll check the girls tonight and if the are wet enough I'll feed and at a higher volume. If they aren't ill wait till they get their full water. MY WIFE WAS HAVING AN "MEDICAL PROBLEM AND SO ON THE WAY TO THE DOCTORS I CHECKED THE PLANTS. THE 10TH PKAMETS WRRE DROOPING. I QUICKLY MIXED UP ENOUGH TO FEED EVERYTHING AT LEAST A GALLON AND THEN GAVE THE ONES THAT WERE THE WORST LIKE AN EXTRA HALF GALLON. JUST ENOUGH TILL WE GET OUT OF THE ER THEN I'LL GIVE THEM THE OTHER HALF OF WATER AND ILL FEED THEM. AT LEAST MY WIFE IS OK. UPDATE: Took my wife to the hospital. They did a shit ton of nothing which is par for the course. However, luckily for me (yeah right) I got back early enough to give the plants another half gallon of water each and then I fed increasing the volume to 2.5 pints (upping the big bloom to 3 tsps per gallon) but I ran out of feed on the last plant. I only mixed up two gallons and it was super dark so thar one container plant will need to be fed tomorrow I guess. This is masterofsmeagal signing off to fucking FINALLY get stoned!

all nutrients are in ger section if not other mentioned all by maufactures instructions. no problemsso far she looks a liilt rough but she should do fine.

April, 20th Happy 4:20 to all People The first Thinng when i open the Tent is smelling such lovely Scents, flowery spicy... whateveer Then looking at those Peaks they Produce,.....😍 and I start aBIIIIIG Smile😁 Girls doing fine Flowering and Flowering,,, Feeding every other Day , I added Organic More PK, because they need it now Watering often with all Beneficals they need now

Vamos familia, actualizamos la octava semana de floración de estas Frosty tooth de Seedstockers, aplicamos varios productos de Agrobeta, que son increíbles para aportar una buena alimentación a las plantas. Temperatura y humedad dentro de los rangos correctos dentro de la etapa de floración. La tierra utilizada es al mix top crop, por cambiar. De 5 ejemplares seleccioné los 3 mejores para completar el indoor y trasplanté directamente a macetas de 7 litros, el fotoperiodo a 12/12, aplique una poda de bajos, se ven bien sanas las plantas, tienen un buen color, las plantas ya tricomaron mucho, una locura, maduraron bien ya creo que les daré matarile pronto. Agrobeta: https://www.agrobeta.com/agrobetatiendaonline/36-abonos-canamo Hasta aquí todo, Buenos humos 💨💨💨.

Hello to all my friends and usual visitors. Thank you for stopping by and all the likes and comments....you are the best! 😎 Everything goes according to plan i started adding PK 13/14 to the mix this week, the plant is in good condition and seems to recover nicely. The excellent Mars Hydro TS 1000 is kept at 33 cm from the top of my plants is is running on full power. TS 1000 gives a full spectrum of light to the plants and you can see that...the leaves are lush green and develop without any hindrance, Mars Hydro did a very good job producing this lamp. Thanks to Mars Hydro for supplying the necessary equipment for this grow. That's it for this week folks, have a wonderful week and please come beck visit in three days time. 🙏

Lento desarrollo seguimos con fuertes lluvias saludos

Sorry for the delay was in a wedding this weekend came home and been trimmin like a dog the past few days but I gotta feed everything in this tent tmm so I'm gunna get some pics. If your interested in the pics come back tmm night.

0.23v tuned to 7.83Hz Plants exposed to the Schumann resonance often show greater resistance to stress factors such as drought, diseases, and pests. It is possible that these natural electromagnetic waves strengthen plants' immune systems and increase their ability to resist disease. Pretty neat, in the afternoon when the tent hovers around 84F the plants are 🙏, can visually see in time around 10 minutes after I opened the tent the temp had dropped to 76 pressure was lost, she is still chilling but she doesn't quite have that perk anymore. *Salinity3.5% - 100ml H2O=100g The concentration of salt in a solution 3.5%= 3.5g in 100ml. Growing well. Not going to top or do any training, I'll let the plant do its own thing, she is constructing foundations now for what she senses ahead. Smart girl. ✨️ Let her, do her thing, let me do mine. The voltage that is needed for electrolysis to occur is called the decomposition potential. The word "lysis" means to separate or break, so in terms, electrolysis would mean "breakdown via electricity. Green hydrogen is hydrogen produced by the electrolysis of water, using renewable electricity. The production of green hydrogen causes significantly lower greenhouse gas emissions than the production of grey hydrogen, which is derived from fossil fuels without carbon capture. Electrolysis of pure water requires excess energy in the form of overpotential to overcome various activation barriers. Without the excess energy, electrolysis occurs slowly or not at all. This is in part due to the limited self-ionization of water. Pure water has an electrical conductivity of about one hundred thousandths that of seawater. Efficiency is increased through the addition of an electrolyte (such as a salt, acid or base). Photoelectrolysis of water, also known as photoelectrochemical water splitting, occurs in a photoelectrochemical cell when light is used as the energy source for the electrolysis of water, producing dihydrogen . Photoelectrolysis is sometimes known colloquially as the hydrogen holy grail for its potential to yield a viable alternative to petroleum as a source of energy. The PEC cell primarily consists of three components: the photoelectrode the electrolyte and a counter electrode. The semiconductor crucial to this process, absorbs sunlight, initiating electron excitation and subsequent water molecule splitting into hydrogen and oxygen. Water electrolysis requires a minimum potential difference of 1.23 volts, although at that voltage external heat is also required. Typically 1.5 volts is required. Biochar, a by-product of biomass pyrolysis, is typically characterized by high carbon content, aromaticity, porosity, cation exchange capacity, stability, and reactivity. The coupling of biochar oxidation reaction (BOR) with water electrolysis constitutes biochar-assisted water electrolysis (BAWE) for hydrogen production, which has been demonstrated to reduce the electricity consumption of conventional water electrolysis from 1.23v to 0.21v. Biochar particles added to the electrolyte form a two-phase solution, in which the biochar oxidation reaction (BOR) has a lower potential (0.21 V vs. RHE) than OER (1.23 V vs. RHE), reducing the energy consumption for hydrogen production via biochar-assisted water electrolysis (BAWE). BAWE produces H2 under 1 V while eliminating O2 formation: key word "eliminating". Air with a normal oxygen concentration of around 21% is not considered explosive on its own; however, if a flammable gas or vapor is present, increasing the oxygen percentage above 23.5% can significantly increase the risk of ignition and explosion due to the enriched oxygen environment. The addition of ion mediators (Fe3+/Fe2+) significantly increases BOR kinetics. Air: Nitrogen -- N2 -- 78.084% Carbon Dioxide -- CO2 -- 0.04% Hydrogen in homosphere H -- 0.00005% Hydrogen "GAS" H2 in homosphere - 0% "Nitrogen, oxygen, and argon are the three main components of Earth's atmosphere. Water concentration varies but averages around 0.25% of the atmosphere by mass. Carbon dioxide and all of the other elements and compounds are trace gases. Trace gases include the greenhouse gases carbon dioxide, methane, nitrous oxide, and ozone. Except for argon, other noble gases are trace elements (these include neon, helium, krypton, and xenon). Industrial pollutants include chlorine and its compounds, fluorine and its compounds, elemental mercury vapor, sulfur dioxide, and hydrogen sulfide. Other components of Earth's atmosphere include spores, pollen, volcanic ash, and salt from sea spray." Although the CRC table does not list water vapor (H2O), air can contain as much as 5% water vapor, more commonly ranging from 1-3%. The 1-5% range places water vapor as the third most common gas (which alters the other percentages accordingly). Water content varies according to air temperature. Dry air is denser than humid air. However, sometimes humid air contains actual water droplets, which can make it more dense than humid air that only contains water vapor. The homosphere(where you live) is the portion of the atmosphere with a fairly uniform composition due to atmospheric turbulence. In contrast, the heterosphere is the part of the atmosphere where chemical composition varies mainly according to altitude. The lower portion of the heterosphere contains oxygen and nitrogen, but these heavier elements do not occur higher up. The upper heterosphere consists almost entirely of hydrogen, cool. 78%nitrogen as N2, a far too stable bond to be used by organisms. 20%oxygen 0.04%co2 0.00005% hydrogen When lightning strikes, it tears apart the bond in airborne nitrogen molecules. Those free nitrogen atoms N2 nitrites then have the chance to combine with oxygen molecules to form a compound called nitrates N3. Once formed, the nitrates are carried down to the ground becoming usable by organisms. Will it react with the oxygen in the air spontaneously, the answer is no. The mixture is chemically stable indefinitely. A mixture with air near the release point can be ignited, but if this does not happen then when its concentration gets below 4% it will be unable to carry a flame. Taking a small detour into chemistry here, a key concept to understanding the health impact of nitrogen-based compounds is knowing the difference between nitrates and nitrites. What Are Nitrates and Nitrites? A nitrite (NO2) is a nitrogen atom bonded to only two nitrogen atoms. Very strong bond A nitrate (NO3) is a nitrogen atom bonded to three oxygen atoms. Weaker bond The optimal pH for nitrate (NO3-) depends on the process and the type of bacteria involved. Nitrification The optimal pH for nitrification is between 7.5 and 8.6 Nitrification is the process of oxidizing ammonia to nitrate and nitrite Nitrosomonas has an optimal pH between 7.0 and 8.0 Nitrobacter has an optimal pH between 7.5 and 8.0 Nitrification ceases at pH
