BrediniGreeny Welcome to what Iโ€™m calling my Mephisto Genetics Experiment!๐Ÿ˜„ Why the dramatic name? Because the summer forecast is hotter than a jalapeรฑo in a sauna.๐Ÿ˜ซ๐Ÿ˜ซ. Weโ€™re about to find out how well we can dance through the heatโ€”me, my plants, and the mighty air conditioner. Iโ€™ve already ordered a mobile AC unit to keep things chillโ€”literally. On May 15th, I kicked off the experiment by putting a Forum Stomper from Mephisto Genetics bean to germinate. I couldnโ€™t stop myself there (classic me), so on May 17th, I added a Double Grape to the mix becauseโ€ฆ letโ€™s be honest, that grower itch is real, and I just had to scratch it. Now hereโ€™s the twist: I'm keeping these seeds in the good olโ€™ wet paper towel method, tucked gently inside a plastic container. But hereโ€™s where it gets a bit oddโ€”theyโ€™re always with me. Like, on me. Iโ€™m experimenting to see if my body warmth helps with germination. Will it make a difference? Will I become some kind of sprout whisperer? Only time will tell. So that's it for now. Two seeds, one AC unit on the way, and a summer of sweaty suspense ahead. Letโ€™s see how this goesโ€”stay tuned and root for me (pun very much intended)!๐Ÿ˜๐Ÿ˜› 5/19/25 May 19th โ€“ We Have Liftoff! ๐Ÿš€ Todayโ€™s the day โ€“ both seeds have germinated! One of them, our little Forum Stomper, ditched her helmet (left her seed shell behind in the paper towel) and even spread her cotyledon leaves while I wasnโ€™t looking. The other, Double Grape, is just starting to show her taproot. I placed them both into pre-soaked coco tablets (soaked in pH 6.5 water with 0.1ml of root juice). Gave them a nice mist with room temperature water, tucked them into a glass container, and now itโ€™s up to them. Fingers crossed, but for now โ€” liftoff achieved! ๐ŸŒฑโœจ 5/23/25 The Mephisto Genetics experiment is going really well. The little ones are now a bit bigger and just moved into larger pots. I used BioBizz Light Mix with added perliteโ€”about a 50/50 ratio. I also added TNC Mycorr Plus for beneficial fungi and microbes. To protect the roots from fungus gnats, I topped the soil with a layer of clay granules and a bit of sand. The Double Grape is looking good, just slightly crooked from chasing light on the windowsill. Forum Stomper had some trouble with her cotyledons, but she's pushing out her first true leaves now and looks like she'll bounce back.๐Ÿ™๐Ÿ’š I also gave them about 150 ml of water total, pH 6.3, PPM 105, at a temperature of 22.5ยฐC. Each plant got roughly 75 ml. Theyโ€™re now in the tent where just one SF-1000 is on over the Gelato Auto, far away๐Ÿ˜ and receiving around 168 ยตmol/mยฒ/s PAR. Stay tunedโ€”things are looking promising.๐Ÿ˜Š๐Ÿ’š๐ŸŒฑ

BrediniGreeny 5/25/25 Veg Day 1 My little Mephisto Genetics babies are off to a solid start! ๐ŸŒฑ Theyโ€™re about 2cm tall now and looking lively. One of them (Forum Stomper) had a rough start with some cotyledon leaves drama ๐Ÿ˜ฅ, but sheโ€™s bounced back and is pushing out her first true leavesโ€”back on track and keeping pace with her sister. Double Grape is thriving๐Ÿ˜ ! 5/27/25 So after asking my grow question and getting a ton of great responses (huge thanks to everyone!), I decided to recheck the DLI for all the plants to see exactly where things stand. Ended up adjusting the positions a bitโ€”now the healthier-looking Double Grape (aka Grapey) is sitting at around DLI 14, and the Forum Stomper (Stompy) is getting about DLI 11. Hopefully that helps balance things out! Also had a hunch that the layer of sand on top of the soil might be limiting oxygen flow to the roots. After reading through all the helpful feedback, that hunch got confirmedโ€”big shoutout to @Ultraviolet for the clarity and good vibes! Lesson learned: sandโ€™s fine later on in air pots, but not ideal for young plants in regular plastic pots. Noted! They also got a little treat todayโ€”about 100ml of water each with a sprinkle of cinnamon. Going in PH 6.5 ppm 112 temp 21ยฐC. Grow babies, grow! Much love โ€“ ๐Ÿ’š๐Ÿ’š๐Ÿ’š๐ŸŒฑ 5/28/25 The little Mephisto girls got their own tent now! I moved them in to get better control over the light and overall conditions. I wasnโ€™t liking how the Double Grape was chasing the light from the flowering Gelato, so this should keep things more dialed in. The Spider Farmer 32W under-canopy/veg LED lights arrived today โ€” I ordered two sets, and I installed one in the new Spider Farmer nursery tent. That space will now be dedicated to early veg and seedling stages. I set the light schedule to 20 hours on / 4 hours off, which gives them just over 10 DLI. Super hyped to see how the Mephisto girls take off in their new setup!๐Ÿ˜Š 5/31/25 Today I gave both Mephistogenetic plants some light watering. Each one got about 150 ml of water, mixed with: 0.2 ml Root Juice; 0.15 ml BioHeaven ; 0.15 ml ActiVera The pH going in was 6.1, PPM at 160, and water temp was 23ยฐC. After watering, I put both plants on the counter near the sink. As I moved around I flung Forum Stomper into the sink. The soil spilling everywhere and "Stompy" ending up just in the coco puck with roots ticking out. I replanted it but I think that was it for her. She was already not growing very good. I am very, very disappointed in me. I don't know but since I started documenting my grows here I have a lot of bad luck. I think I should stop and just grow for myself. What's even the point in posting ?!? ๐Ÿ˜’๐Ÿ˜’

Hi GrowmiesโœŒ๏ธ๐Ÿ’š๐ŸŒฑ I am looking for opinios on what my little one has? And what can I do to help her, if anything? Started her 2 days before the Double Grape, she germinated first, had problems with cotyledon leaves from the start. Even when they weren't green,they had spotsThx

Pot looks ceramic or plastic, limiting oxygen. Sand can act as an effective oxygen barrier, particularly when combined with other materials in a layered system designed to control water infiltration and oxygen diffusion. This is because sand's coarse nature and the resulting spaces between grains can limit the passage of oxygen through the soil. Oxygen readily diffuses through air, but its diffusion through water is significantly slower (up to 10,000 times slower). Sand is creating a moisture-retaining layer (MRL), hindering oxygen diffusion. God bless those hydroton pebbles. Phosphorus is an essential plant nutrient, and its availability in the soil is strongly linked to the presence of oxygen. Plants primarily absorb phosphorus as phosphate (PO4), and oxygen is a key component of this molecule. Furthermore, the availability of phosphorus in the soil can be impacted by factors like soil aeration and temperature, which in turn affect the oxygen supply to the roots. Phosphorus uptake in plants is most critical during the early stages of growth, particularly within the first few weeks of plant development. Young plants actively growing tissues have a high demand for phosphorus. They may absorb up to 75% of their total phosphorus requirements within the first few weeks of vegetative growth, with studies indicating in controlled environments up to 51% of uptake happening overnight, primarily in the first few hours or early nightfall. Anaerobic respiration, unlike aerobic respiration, doesn't utilize oxygen as the final electron acceptor in the electron transport chain. This results in a significant drop in the amount of energy (ATP) produced, which is necessary for various plant functions, including growth, nutrient uptake, and maintenance of cellular processes. In the absence of oxygen, cannabis produces byproducts like ethanol and lactic acid during anaerobic fermentation. These byproducts can be toxic to the roots and inhibit their function, the lack of oxygen in the plant medium leads to a decrease in pH due to the production of carbon dioxide during anaerobic respiration and impaired pH regulation within the plant. You can survive weeks without food. You can survive days without water. You can survive minutes without oxygen. You can survive 16 seconds without ATP.

BrediniGreeny 6/1/25 Starting a new week. Stompy turns out to be a mutant๐Ÿ˜[for now, until she shows me some normal leaves]. Grapey is growing strong๐Ÿ’š Although Stompy germinated first, she is more then twice as small as her sister Grapey๐Ÿ˜Š No matter, I will keep them both, give them care and love and see if Stompy surprises me๐Ÿ˜. 6/4/25 Today they got 150 ml of water each with: RootJuice 0,2ml; Activera 0,2 ml; BioHeaven 0,2ml; CalMag 0,15ml. Going in PH 6,2 ppm 230 temp. 23ยฐC.

BrediniGreeny 6/8/25 Starting a new week. Very good, growing.๐Ÿ˜๐Ÿ’š They got around 200ml of water each with: RootJuice 0,4ml; Activera 0,2ml; CalMag 0,3ml Going in: PH 6,16 ppm 260 Temp 25ยฐ Grow babies groooow๐Ÿ˜๐Ÿ‡๐Ÿ‡๐Ÿ‘ฃ๐Ÿ’š๐ŸŒฑ 6/10/25 Grapey is doing very good, soon to be transplanted๐Ÿ’š๐Ÿ‡๐Ÿ‡ Stompy on the other hand is throwing another set of mutant leaves๐Ÿ˜…๐Ÿ’š i am very interested where the journey will go๐Ÿ‘ฃ๐Ÿ’š 6/12/25 Both Grapey and Stompy got transplanted today๐Ÿ’š I decided to go for a 15l "High Edition" Rooties textile pot for Grapey and for a 6l Rooties textile pot for Stompy๐Ÿ˜Š. My decision is based on Stompy not growing so vigorously. I think she will be a small plant. Grapey might be a medium-small plant because of not transplanting sooner๐Ÿ˜ I don't mind ๐Ÿ˜Š The first layer that went in the pots, so the last layer the roots will reach, was composed of: BioBizz Light Mix, Perlite, a little bit of Worm Hummus, a sprinkle of spent coffee grounds, a sprinkle of guano and a sprinkle of TNC MycorrPlus. The layer is about 10 cm or such. On top of that i added just BioBizz Light Mix, a sprinkle of spent coffee grounds and a sprinkel of TNC MycorrPlus๐Ÿ˜. As for the top soil I put the little stones that i use in the last time. Gave them both 500ml of water with PH at 6,2 ppm around 115 temp 23,5ยฐ C.๐Ÿ˜Š Grapey got the top 2 fan leaves cut down so to slow down the main and introduce more light to the other nodes.

BrediniGreeny 6/20/25 Starting a new week and doing just fine. ๐Ÿ’š Grapey is showing preflowers๐Ÿ˜ Stompy is really small and kinda bushy.๐Ÿ˜…๐Ÿ˜… ๐Ÿ’š 6/21/25 Today I thought, okay, Grapey is going into flowering โ€” sheโ€™s showing pre-flowers โ€” so she got a guano top dressing. I did it how I felt like it, didnโ€™t measure how much I put in, just kind of like what I did with the Gelato automatic plant. Then she also got 1.4 liters of water with RootJuice, 4 ml Activera, 3 ml BioHeaven, 3 ml Algamic, 3 ml SiCaMag 0.1 ml CalMag 0.5 ml . Going in, pH was 6.2, PPM at 250, and water temperature at 22ยฐC. I also topped her โ€” I donโ€™t even remember when, I did it spontaneously โ€” and yeah, did some LST on her. I try to look for little signs of flowers or nodes starting down in the under canopy (if you can even call it that since sheโ€™s small) and I plucked like two, not really much yet. Stompy, on the other hand, is super bushy and still not showing any pre-flowers, so sheโ€™s staying in veg and just growing and growing, making very big leaves. She got the same water: 1.4 liters with the same nutrients as Grapey, just without the guano top dressing. Weโ€™ll see what happens. 6/25/25 Grapey has just a little too much nitrogen, but she will make it.๐Ÿ˜…๐Ÿ’šโค๏ธ๐ŸŒฑ Stompy is showing vigorous growth all of a sudden. With big leafs almost as big as my hand๐Ÿ˜ that's why they needed to go to make light available for the bushiness beneath๐Ÿ˜…๐Ÿ’š๐ŸŒฑ Today, Grapey got 2.1 liters of water with Activera 4 ml, BioHeaven 3 ml, Algamic 3.5 ml,SiCaMag 0.15 ml, BioBloom 4 ml, and TopMax 1 ml. Going in, pH was 6.4, PPM at 242, and water temperature at 22.5ยฐC. Stompy also got 1.4 liters of water with Activera 3 ml, Algamic 3 ml, BioHeaven 6 ml,SiCaMag 0.15 ml, and BioGrow 1.5 ml. Going in, pH was 6.3, PPM at 261, and temperature at 22.5ยฐC.
