Really hot. Using more water. About 2 gallons a day each pot. Watering daily. Summer peak hits in the next month, then comes the wind down to the season...from September to Croptober. I don't see as much stretching as I see buds coming in right now, which is really exciting. Wind: I usually experience strong winds for the end of August and start of September. This means that I am taking the canopy down and letting the sun hit the plants with all its force for the remainder of the season. More water means fatter nugs. Nutrients: Day 105 - 21 August 2024 - Added 1 cup Bud Candy and 1/2 cup Overdrive from AN, then added 2 gallons of water in a large watering can. I let that sit for 2-3 hours, then I add it equally to the four pots. I'm alternating this and kelp meal biweekly from Down to Earth (every 2 weeks). This recipe is gentle and it works for me. Thank you to all following the grow. Straight up... each plant looks a little different - my guess it's because of all the crosses behind the genetics. Basically looks a little Malawi, a little tropicanny, a little cookie, and sour orangey for sure. I don't care for a stable line where all the plants look homogenous (basically the same, I may have messed up the description) - I just want something that will have a good end product and these plants all look fine to me. Now I just have to be vigilant so that the caterpillars don't destroy all the flowers. It's a bit nerve wrecking, but I'm committed to not using pesticides or insecticides - organic or not. I'm also considering washing the herb at harvest--that's got me a little nervous also because it gets really humid around harvest time, but all the testimonials and videos I've researched all seem to agree that it does not affect the end quality in terms of effect since THC is basically water resistant, not water soluble or something--i'm thinking water hash in my head to comprehend the science a little better. That's it. Just a few more weeks to go. About 8.

7/18 I'll make this week a six day week to get back on track since i didn't last week. Rhis has been INCREDIBLY challenging for me to be away from my plants for this long. It will be six days. I'm leaving early to come home and water. We are supposed to get thunderstorms. Not sure if we did but it's only 11am. All pics so far are ones sent to me this morning. It rained a little bit yesterday. I have a lot to do in the garden. I need to assess Amy damage. Probably water (depending on weather), defoliate and hunt pillars. I may decide to spray and I may not. Depends what I see. Plants are getting big though. I'll need to add the second set of supports. I'm hoping I come back and find inch long buds like I did last time with those mendo breath that flowered super early two years ago. I just want to see my girls and take a big deep breath of their smelly goodness. I need to check for deficiencies as well as i usually started nutes by now. Tomorrow morning I'll do a video when I get back. UPDATE: AROUND 7 O'CLOCK MY INTUITION OR AS I CALL IT "MY SPIDY SENSE" STARTED TINGLING. IT HAD BEEN EARLIER BIT I IGNORED IT. I PLANNED FOR TWO THUNDERSTORMS WE GOT HERE AND WERE SUPPISED TO GET AT MY GROW BIT DIDN'T GET. I FIGURED THE GIRLS WOULD BE OKAY BUT I COULD FEEL THEIR PAIN. I COULDNT REALLY TELL THROUGH THE CAMERA IF IF THEY WERE DROOPING BAD SO I HAD DAD GO LOOK. HE DIDNT RESPOND WHICH PISSED ME OFF. I TOLD HIM THIS MORNING TO KEEP A VERY CLOSE EYE ON THEM AND IF NEEDED TO WATER THEM. NOT WANTING TO ASK TO MUCH OR I WOULDVE JUST SAID DO IT. HE WATERED EACH PLANT A HALF GALLON AND SPLIT A GALLON WITH THE 10 GAL AND THE 5 AND 50 GALLON SEEDLING CONTAINERS. I'M GLAD I CAUGHT THIS. I NEED TO INCREASE THE AMOUNT OF WATER. AT LEAST I HOPFULLY WONT COME HOME TO DROOPING PLANTS. THAT WOULD BE A KICK IN THE NUTS. I'M NOT GOING ON VACATION DURING GROWING SEASON AGAIN. I CANT WAIT TO SEE MY GARDEN. 7/19 Came home to the plants looking okay but very light and needing water. All expected storms missed us so what I planned for water wasn't enough. Plus they are much larger. DAD WATERED ALL CLONES WITH A HALF GALLON OF WATER AND THEN I GOT BACK AROUND 10ish AND GAVE THE PLANTS ANOTHER FULL HALF GALLON. THE GMOs ARE DEFINATELY WATER HOGS. I've noticed some interior leaves fading so I'll start nutes soon. Saw some pillar damage (and the pillar in a picture dad sent) and went hunting. I caught 11 caterpillars!!! Three different species. A big green one that rolled into a ball. Yellow and green normal moth larvae and an inch worm the color of an earth worm! I found no eggs though. I took a video, but I'll have to wait to upload it. Luckily, my intuition is on point, and I have family that will help me. All it takes is a day of this heat advisory over 100f weather and the wind to dry my bags right out! I don't want to over water, but 10% is 2 gallons in the 20s. I'm upping the water to a gallon a plant. The event horizons seem to be a little further in flower and don't seem to be using AS much water. I'll play it by ear. I was going to spray bt but having caught double digit pillars I think I'll hold off and do what I'm doing. I can always spray later if needed. 7/20 Checked my plants late and noticed they were light and starting to droop. I had one gallon mixed up so I gave to what was worse. They seemed like they would be OK until after my wife's doctor's appointment. I got back and EVERYTHING but one event horizon were starting to droop and light as a feather. This was after I gave them half a gallon yesterday afternoon and dad gave them a half gallon the late night before. The plants are just too big and with this heat they need more water. I mixed 8 more gallons amd gave each plant a full gallon. Used another gallon earlier in the morning so a total of 9 gallons was used on the garden today. I defoliated what I could. I noticed a hole in my cage as well. A lathe broke and it left a small hole for an animal to crawl through. I found a small lathe and got the drill and went around and repaired the cage. I have a lot more to do. Some serious defoliation. I need to start nutes and I need to add the second supports which is a trellis. That way I can LST. The cages kinda hold everything close together but once the supports are added things while be spread out much better. Much more room this year. I need to switch the plant in the 10 with the flowering event horizon to better utilize space. Dad says these are the best looking plants I've grown. I don't know if I agree but the are really thick. Could just be the strain. I'm certainly not complaining. Things look good. If I can hunt pests myself I'd rather do that than spray chemicals. Got a few more pillars and jpn beetles. Took a video but it won't upload until tomorrow. 7/21 It was definately a good idea to up the watering amounts. If not they'd probably be dead. They are growing at a significant rate. Some seem to be in early flower. I have damage from pillars but considering how many I've caught from hunting im still on the fence about spraying. I probably still should. I went through abd manually removed as many as possible. When I went over this morning I checked the weight of every plant. Every plant was noticeable lighter than after I had watered them yesterday. That kinda suprised me. My water hogs were actually significantly lighter. We haven't been getting rain either. I'm going to have to water every day. I think a gallon a plant should be enough. 10% is 2 gallons though. I'd rather understand water than over water but I'd like to get it so I'm not watering every day. Or every other day which I'm sure is what will happen. I'm planning on having to water tomorrow. I'm still going to mull over whether I should apply the BT tonight or not. I probably should. They aren't a problem now but further in flowering they wreck havoc on flowers. Eating and shitting and spreading mold every where they go. There's no way I got all of them. I keep saying it but never do it but I should get netting. That would basically solve this problem. Oh, didn't get a chance to upload the video I made. I'll do it tomm. UPDATE: THAT "SPIDEY SENSE" STARTED TINGLING AGAIN SO I DROVE TO INSPECT MY PLANTS. ITS BEEN SUNNY AND HIGH 80S/90. ALMOST ALL PLANTS WERE DROOPING. SOME WERENT FEATHER LIGHT BUT THEY WERE LIGHT AND DROOPING. THE WIND WAS WHIPPING AND WHEN IT DOES THAT IT DRIES THOSE BAGS OUT QUICK. INTERESTING ENOUGH THE EVENT HORIZON THATS IN THECMIDDLE OF THE CAGE SURROUNDED ON ALL SIDES ABDCPROTECTED FROM THE WIND STILL HAS WEIGHT. IT LOOKED A LITTLE DROOPY BUT DOESNT GETCTHE WIND THE OTHERS DUE. IM WONDERING IF I COULD BE OVER WATERING THAT ONE PLANT WITH THE FREQUENCY OF WATERING. THE SOIL WAS DUSTY AND DRY BUT WHEN I STUCK MY FINGER IN SOME DIRT STUCK TO IT SO I DIDNT WATER THAT ONE PLANT. I MIXED UP EIGHT GALLONS OF WATER AND GAVECEVERYTHING A GALLON. I GAVE A HALF GALLON TO THE PLABT IN THE 10 AND BRIEFLY HIT THE CONTAINER PLANTS. THE REMAINING HALF GALLON WAS ADDED TO THE PLANTSCTHAT ARE USING THE MOST WATER. GMOS WERE USING MORE THAN ANYTHING BUT THAT SHERB PIE AND TOASTED TOFFY SEEM TO HAVE CAUGHT UP. LOOKED FIR PILLARS BUT COULDNT FIND ANY. ILL UPDATE TOMORROW. IM WONDERING IF I SHOULD GO FOR A GALLON AND A HALF EVERY TWO DAYS OR A GALLON A DAY DURING THIS HOT WEATHER. LUCKILY I CAN KEEP AN EYE OUT AND FIGURE IT OUT. I HAVEXA COUPLE PLANTS THAT ARE TRANSITIONING TO FLOWER. EXCITING TIMES! OH AND AFTER WATERING THE GIRLS PICKED THEMSELVES RIGHT BACK UP. I KNOW ITS NOT IDEAL BUT ITS BETTER TO UNDER WATER THAN OVER WATER. I STILL HAVE NIGHTMARES ABOUT FUSARIUM. 7/22 Much cooler day. It's 74 at 9:40 bit it was 60 earlier this morning. With the cooler weather I'm hoping I won't have to water as often. I think I hadn't been giving them enough water at a time for the conditions. I'm not going to water again until all bags are super light. That's what I had been doing but I don't want my plants getting to the drooping phase. Luckily I check on them multiple times a day and I've got the cams. I caught approx half a dozen inch worms this morning. I'm wondering if I should still spray. If I'm catching this many there has to be more. I'm not removing the damaged leaves if they aren't bad so it's hard to tell if it's new damage. It was extremely windy yesterday. I assume that is what helped dry the bags put so much. I already doubled the water intake so I don't want to do anything else until I see how this turns out. I figure I'll have to water tomorrow. We are getting some rain in the next few days but not much. 7/23 This will be the last entry for this week so I can get back on track. If you've been following along you'd see that I had pretty much doubled my watering amount due to it not lasting until next watering. I take the weather reports I to account. They have really been passing me off lately. On vacation we were supposed to get two large storms at my grow. We got ZERO rain amd it just followed me to my vacation (where the weather WAS supposed to be sunny) and poured some of the heaviest shert rain I've seen. Now after I over watered my plants (just a litttle) I found out the weather changed. Today, tomorrow and Wednesday we were supposed to get TINY amounts of rain. It totaled like .35in for the 3 days. I'm thinking cool. Instead it get changed last minute to supposably get an inch of rain JUST today. It was sheet rain earlier but it has totally stopped raining. The GMOs aren't really over-watered (too bad at least) and look normal. Nothing looks BAD. I can just tell by the weight that some of these girls are overwatered. That's OK though. If we get any wind (which we should) it will dry those bags out quick. With the gmos and that sherb pie it would be very hard to overwatercto the point where it hurts the plant. I just need to realize the GMO'S just use more water. They are asparagusing right up. Event horizon is in early flower. Everytime I go to my grow I'm able to kill multiple pests. I got at least 5 moth larvae, a couple moths, couple leafhoppers and I missed this giant grasshopper that had been going to town chomping leaves. I think it's time to start nutes. I also think I'm going to spray either BT or captain Jack's after this rain. I don't need pillars come flower. Since I can SEE multiple pests it might be best to use something broader like spinosad but we will see how it goes. I also need to switch a couple plants for better room, defoliate and add the trellis and second set of supports. The first support kinda keeps the branches together so I need to lst and tie down branches to open up the plant.

Aug 3: this is a very promising looking plant. She’s quite big and flowering quite quickly which is a great combo. She was the exact same size as my other photoperiod until the start of flowering two weeks ago, and now she’s bigger and flowering faster. Humidity is quite low during the day so I’m continuing to mist the leaves a few times during the day. Did a foliar spray of Extreme Blend and potassium silicate this morning. Aug4: did a major defoliation to remove small lower buds and stuff that was growing in toward the centre. This improves light penetration and air flow which are super important but also forces the plant to direct the energy where you want at the main colas, and not wasted down below. Aug 5: lots of buds forming quickly on lots of decently uniform colas. Should be good. Big rain last night but plants were in dark garage. Watered this morning with 27 C water that had blackstrap molasses, soluble seaweed extract, Monster Maxx and Cal-Mag. Did all four on the weak side of the standard concentrations listed and just 1L used on the plant. Much cooler today so she won’t need as much water. Aug 6: added UV lights from AC Infinity. Very well deigned and manufactured like all of their gear. These are indoor lights so fair weather use only. This far north (53 N) we run out of strong sunlight before it gets too cold in the fall. Idea is to use UV lights for a couple hours each day centred at peak sun (currently 1:39 pm). UV light is the main environmental limit on THC and this will make the light in Edmonton in September more like California in July. Should have a big impact this far north. At other end of light spectrum, I use Forever Green Indoors (FGI) 730 nm far red light as a bloom booster. A few seconds at dusk is all it takes for the far red light. This is the third season using the far red light and it definitely works. #seedsman420growoff #seedsmanseeds

Day 85 Day 1 Flower 26/07/24 Friday Big feed today full 5L a little run offusimg de-chlorinated water pH 6. So we are through her first transition week. Starting to see sex pistils forming at end of last week. Picture and video update ✌️💚 Day 88 Day 4 flower 29/07/24 Monday Just de-chlorinated tap water pH 6 today, full 5L with just under a 1L run off. Day 89 Day 5 Flower 30/07/24 Tuesday De-chlorinated tap water pH 6 today but I'm adding in Plagron Power Buds AND Plagron PK13-14 only 5ml each to 5ml water. It says to use on every irrigation from early flower so here we go. If I start getting burns I'll cut out a few advanced nutrients extras and go again from there. She is just ridiculous, robust, never stresses, healthy and just wants to throw arms out everywhere 🤣💚 Day 91 Day 7 flower 01/08/24 Thursday End of week. Another feed today using de-chlorinated tap water pH 6, there now taking 3L every evening.

Week 9 concluded with great progress and minor issues! She continues to stack on inflorescence and is frosting up nicely in the heat of the summer sun here. There hasn't been rain here for some time and the days are well into the 90's Fahrenheit. She spends most of the day outside and still comes into to bask in the 400W HPS while it's dark out. I try to give her a 4 hour lights-out immediately after bringing her inside for the day. I'm seeing leafhopper damage here and there but inspections haven't turned up any culprits recently. I saw them daily back in the spring when she was in veg but they seem to have moved on. I've ordered some spinosad soap in case they continue to damage the plant. As always, I overfed N during flower and she's clawing up a bit on me. Since then, I've been hitting her with plain water only to try and flush out some of the excess. Following manufacturer recommendations for nutrients always seems to bite me. Especially since all say not to stop with Grow, Part A, etc.. once flower begins. Clearly, I'll need to dial back the amount in the future. She seems to be progressing nicely in spite of these few issues though and overall I'm very happy with the genetics Dinafem has lovingly created. Thanks for following along and please click "Like" below if you dig what I'm doing here. Cheers! 👊🌱☮️✌️

The holiday season got away from me a bit and prevented me from getting an update in on Monday but the plants are _really_ taking off. There are now visible bud sites and plenty of them. *Full Disclosure*: I've significantly upgraded my light in my flower tent from a Spider Farmer SF-2000 to a Spider Farmer SF-4000 and, as such, I'll likely see my yield take off quite a bit this grow. It's certainly having an impact on the heat in the tent and, subsequently, the amount of time the in-line fan is running; that being said, the plants appear to be responding quite well! The last two grows I've run have fallen off hard (complete and total yellowing/chlorosis and drying out regardless of consistent watering/light/nutes/pH) around week five of flower and, with that in mind, I'm trying to keep this grow as simple as possible. I'm purposely using no advanced grow techniques where I'd usually top, LST, and HST. The only "advanced" technique I'm using is a bit of defoliation but this is mainly just to avoid some of the dense bottom growth that tends to decrease air flow, increase humidity, and take away from more rewarding top-growth. This week, along with replenishing nutrients, I've fully emptied out and cleaned my reservoir. While doing so, I noticed a fair amount of red-ish algae growth which I'll likely address with more consistent cleaning of the reservoir and some sort of additive (I'd welcome any suggestions and dosage if you've got any suggestions). All in all, great progress.

This is week 2 from our of the humidity dome by the way (more details to come in the week 1 diary). In week 2 these girls are looking very good! Very nice color overall and nice growth. The clones clones I cut before switching mom to flower are taller, but the ones I cut after switching to flower are bushier. There are 7 clones of Cherry by Elevator Supply Co, these are a High CBD Hemp plant that I am growing and will continue to grow for producing CBD products. I am also a licensed Hemp Farmer. Then I have a clone of DinaMed CBD+ from DinaFem and 2 DinaMed CBD+ seedlings. Next, I have 3 clones of Cream & Cheese CBD from Seedsman and 1 clone of Critical+ from DinaFem. Last I have 2 CBD Medi Kush from Spliff Seeds. I have a separate diary for the CBD Medi Kush from Spliff Seeds, check it out 👍 I don't plan on feeding anything for a while and let the plants use up the nutrients in the soil. In the video, the babies are featured starting at the 3:15 mark

Hey still hanging in there ...lost a 200w led ...replaced it and lost the replacement due to loadshedding...i also had aphid infestation due to ants ...yea who knew ...but luckily i got rid of them using some dishwashing liquid (it desolves the oily protection layer on their skin) ...so i got my hopes back up...

5 week was very intense, it showed itself in all its glory. Every day he rejoiced in his delightful forms, and in the middle of the week he had great tension, which, in my opinion, should have led to self-development, stress, a slight light burn. The exhaust fan burned out, I had to install a cooler from the system unit. All that is needed is all that is needed to get the maximum light, and practically every branch and leaf is light, nothing interferes, and the light penetrates into the depths! I want it to be very fast))) I plan to translate it in color for 6-7 weeks, she got a lot of stress, which, in my opinion, is not desirable, naturally, I am not surprised, and it will tell on the harvest . I already have cultivation experience. imitate how an auto color behaves) in general, a high nitrogen content, temperatures over 26 degrees reach 30 degrees at most, considering the variety, not the best GHE fertilizer, light ventilation and my cheap LED lamp, on the fifth week you can get what you see. I am from the first experience that the miser pays twice! Comfort for plants, well, waiting for the first week of flowering, go ahead!

==> Decreased the base nutrients for less Nitrogen She is doing great! Calyxes swelling slowly and uniformly :) Looks more and more like a Chemdawg family strain grown in hydro, as she should :D Will be the biggest harvest, doesn't smell too strong yet and doesn't have the most resin but OG Kush is a legend and the looks don't always correlate with the quality of the effect and flavor. I still have very high hopes for her :D

The time is finally here to post the harvest. I waited till it was all done and dry before updating the dairy so will add in the dry weights next on the 2nd half of the harvest entry. Had some ups and downs with this plant. mainly the extreme yellowing that was happening. I should have treated this faster with a flush but was super reluctant and I feel this has suffered in the end. The top best looking buds could have been larger and the lower ones could have been thicker. There is some smells with this plant but they are not pronounced. Just smells like mild basic weed, this would be one reason not to grow it, however, the crystals on this plant have been the most I've ever grown before. When trimming them every time the scissors snipped or the brush stroked I saw some falling down onto the tray. This plant would be great for making hash. had a good little ball of finger hash at the end of it and will be giving that to my friends to smoke or make a strong edible with. I don't plan on growing this strain out again, the lack of smells and the fact I'm only trying to grow cbd dominate plants is the main reason. If my friends really like this I have some clones so can always give them some. Speaking of clones they are doing well outside, greened up a lot and showing signs of revegging. Took some photos of the weed hang drying on day 1 in the tent and a week later to show how much they shrink. most of the lower growth is quite larfy but will make good edibles or hash, that will be a fun project to do and may include that in my projects diary. That's about all I can think of if you have any questions just ask. m0use Disclaimers: 1. I have divided the total watts of light in half, 300w(150w) for this diary. It will accurately reflect the g/w ratio as the two plants growing in this tent are listed in two separate diaries. 2. I include any shake/trim in my gross totals as I use them to make edibles. 3. I did not follow any proper ways of listing my nutrients. Some are ml/l of total solution watered, others ml/l of total medium and some are just the total amounts I added, not as a ratio.

My light grew for 20 weeks and 4 days, or 144 days. almost 21 weeks total. $35.67 / 144d = 0.2477$/d average of about 25c a day in electricity 337.2kw for the entire grow. Using the regular calculation of grams harvested divided by watts used is not accurate to me, it does not account for all the time the lamps are on, the length of grow to the over all cost. The calculation that makes sense to me is this, harvested dry weight of usable cannabis buds/trim/keif/whatever in grams divided by total kw used. Could also combine it with grams per total single use costs “anything you used only for this grow and wont reuse in the next, or fractions of multi use items like fertilizers if they ½ full” and see how much you’re investing per gram. "kw" ÷ "g" = kw/g "$" ÷ "g" = $/g I have harvested 5.34oz or 151.6g on 337.2kw. 337.2kw ÷151.6g = 2.22 kw/g of usable cannabis. This is not an ideal ratio for me and looks like a lot of energy waste happened from the extended veg period. $35.67 ÷ 151.6g = 0.24c/g It cost 24c/g when comparing total electricity cost to gross yield, almost identical to the comparison of total electrical cost to the number of days in the grow 25c/day. Neat! legend, kwh = kilowatt per hour kw = kilowatt w = watt h = hour c = cents $ = dollars d = day LED= Light Emitting Diode
