Hi folks, Trying to start an indoor grow using clay balls and ro water!. Do I need to add calmag to ro water for germination in Rockwall cubes that are already in their final position surrounded by clay balls?. I buffered the balls with 5.8ph ro water and calmag before installation but have not added any calmag since!. It's been 6 days since planting and still no show!. I understand that they may need a few more days yet but wonder if I should add calmag to the water or leave until they sprout .......... assuming they do?. I've germinated using rock wool, 5.8ph RO water (with no calmag) before with no problems,.........however they where in a propergater!. Any thoughts or advice much appreciated as always.... Cheers...

Howzit fellow growers, I recently went full rabbit hole on oxidation — and it's got me rethinking my entire approach to the flowering stage. We all obsess over stability: dialed-in VPD, 40-50% RH late flower, perfect airflow to keep mold at bay, no light leaks, consistent temps. That's table stakes for any serious home grow. But what if we're missing something bigger? What if we could actively combat oxidative stress while the buds are still developing on the plant, not just prevent it post-harvest? Why Oxidation Matters More Than You Think During Flowering Oxidation isn't just a curing/storage villain (where oxygen turns THC into sleepy CBN, kills terpenes, and makes buds harsh and brown). On the live plant, excessive oxygen exposure — combined with heat, light stress, or other factors — can accelerate the breakdown of cannabinoids and terpenes right in the trichomes. Free radicals build up, the plant's natural defenses get overwhelmed, and you end up with buds that look fire but lack that loud smell, potency, or bag appeal you were chasing. Most guides hammer home mold prevention (good airflow, lower RH), but they rarely dive into proactive ways to shield against oxidative degradation during those critical 8–10 weeks of bud swell. What Are Reactive Oxygen Species (ROS)? Explained Like You're 5 Okay, let's break this down super simple. Imagine your plant is like a busy little factory making energy from sunlight (photosynthesis) and breathing oxygen. Sometimes, tiny "sparks" fly off the machines — these are called Reactive Oxygen Species, or ROS for short. They're like angry little molecules (superoxide, hydrogen peroxide, hydroxyl radicals) that zoom around super fast. A few of these sparks are actually helpful — they act like alarm bells that wake up the plant's defenses when something's wrong (like too much heat or a bug attack). But if too many sparks build up (from stress like high temps, bad light, or poor environment), they start burning and damaging the factory parts: the trichomes, the THC, the yummy terpenes — basically turning your precious buds into something less awesome. It's like having a campfire: a little fire keeps you warm and cozy, but too many wild sparks can burn down the whole tent! The goal? Keep those sparks under control so your plant stays happy and your buds stay potent. The Stable Environment Is Key... But What Else? Stability is non-negotiable. But after digging deep, I'm convinced home growers have some under-explored tools to fight oxidation on the live plant: - Boosting the plant's own antioxidants — Think nutrient tweaks that support internal defenses (e.g., balanced micros like magnesium, zinc, or even sulfur-rich amendments that aid glutathione production). - Beneficial microbes — Introducing good bacteria (like certain PGPR strains from Bacillus or Pseudomonas) to the root zone or as inoculants. These little helpers can promote the plant's natural antioxidant systems, reduce stress signals, and help the plant handle oxidative pressure better — all while improving nutrient uptake and overall vigor during flower. - Environmental hacks — Slight CO2 enrichment can sometimes help displace excess O2 or support metabolism, but timing matters (dial it back late flower to let ripening happen). UV-B supplementation boosts resin but can increase stress — so pairing it with countermeasures could be interesting. - Stress minimization — Gentle defoliation to reduce exposed surfaces, strategic pruning for better airflow without shocking the plant, and avoiding extremes that spike reactive oxygen species (ROS). These aren't magic bullets, and most are experimental or niche. The science on live-plant oxidation in cannabis is still emerging (a lot of research focuses on post-harvest or general plant stress), but the logic tracks: reduce free radical damage → preserve more THC, CBD, terps → better end product. My Takeaway (So Far) I'm not throwing out my stable-environment playbook — that's still priority one. But I'm starting to experiment with small additions: tweaking feeds for antioxidant support, adding beneficial microbes early on, and paying closer attention to how light/heat interact with oxygen exposure. If you're a home grower chasing elite quality, this might be the next edge. It's not about reinventing the wheel; it's about adding a few smart layers of protection while the buds are forming. Have you gone down this rabbit hole? Tried any anti-oxidation tricks during flower, like microbial inoculants? Drop your thoughts/experiments in the comments — let's share notes and maybe uncover some gems together. Happy growing, stay frosty, and may your trichomes stay pristine! #HomeGrow #FloweringStage #Oxidation #TerpenePreservation #BeneficialMicrobes

hell all newbie grower here looking to learn and share thanks for having me

superb grow! phat oval grenade buds! ahh they gonna be popping specimens minds into far out space man.

Hello just got back into the growing scene, wishing everyone growing some happy cannadust

Brother. I think your approach here is a bit willy nilly. What you're talking about is just a charactaristic. I understand hunting a specific strain, but in this case it doesn't make a lot of sense. Purple weed is not a specific strain. Even a plant that throws out only green buds can be manipulated to produce anthocyanins (the purple) through temperatures and what not. I've got a keeper cut here that I've been growing for years, if I harvest her during winter the buds are all purple, if I harvest her in summer the buds are all green. That's only scratching the surface, cause now we get into the scientific part of it. Alleles. Genetics. Purple buds can be genetic a genetic trait, where as some plants may never produce anthocyanins no matter what you do, some others may throw out purple without any manipulation. Now take that plant, produce seeds from it and you'll end up with a roughly 50/50 split between genetic codes. Here's a bit of a introduction to breeding and how purple/green is a selective trait when breeding genetics. This will be something called "Phenotypes". You will often hear seasoned growers talk about phenos and "clone only" varieties. Every time you pop a seed you get different phenotype. This means your "XYZ" strain from seed wont look the same as your buddies seed from the exact same strain. In fact, buy a pack of 10 seeds, pop them all and let them teach you about phenotypical expression. Now we get into plant plasticity. The ability of a plant to change it's phenotypical expressions in response to different environments. In a way it comes back to the plant being manipulated in order to get different expressions of the same genetic. This means, even if you do get the exact clone from the mother you're talking about, chances are great that you'll end up with something looking a bit different than what you where hoping for, cause you're growing in a completely different environment than the person who grew it you saw the photos of. Geographically different, environmentally different, hight above sea level differs, temp / humidity / time of year all these factor come into play. If you looking for something purple just buy a whole bunch of good seeds from reputable breeder of strains that are well known to throw out purple colour easily and work your way through them. You'll see what I'm talking about. Some aren't even gona go purple at all. Personally, I avoid any purple with a firey passion. Purple weed tastes horrible, ruins the terpene profile as 99,99% of weed that turns purple has a similar taste. It's something you learn through time, the same strains that turn purple, if you can manipulate them and keep them green you end up with a completely different bud, crazy full terpene profile. As anthocyanin is a compound on its own it's no wonder it has impact on the taste, if it's present to the eyes it'll be present to the taste buds when consuming. Purple weed is only for instagram / photos / bag appeal for sellers. It's a selling point, a gimmick.

No I want to turn an outbuilding Into a grow room of grid that's all

It's Orthosilicic acid, which is the best and most easy form of silica for the plants to uptake. You can use it weekly with your plants and is a great silica supplement.

ahoy, just a few past experiences from seed Peyote purple- green pheno, reported to be a isolated pheno of bubba kush, from cannabiogen seeds
