It will take a life time for that to break down... Copper is actually a trace ELEMENT that cannabis needs and use but in TRACE amounts... By having in the soil the microscopic amounts that comes off is actually beneficial... Macronutrients ( most important ) NPK....nitrogen phoprous potassium plus others that come from nature like oxygen carbon monoxide hydrogen ... Micronutrients.. Calcium magnesium sulfer/iron...trace elements. . theres over 50.. Copper manganese Epson salt zinc silica i can't remember all tge rest.. Suhh wow sorry about this long speech. .lolol

No. Copper is used in plants and the trace amounts left if any will not affect plant. Plastic should be safe as well.

I want YOUR opinions on MY training <3 :)Hey people, this is not an important question, I just want to hear everyones opinion on the training I did today (supercropping, LST and defoliation). Does it look good in your eyes, was it too much, not enough or maybe too early / too late? And what should I do next? Thanks :)))6y ago

Lst and pkI think it will be the last question, I’m questionning myself on lst and pk. I know lst doesn’t harm the plant but did I lst too much so that will answer to the question that they’re so f*ing slow or I’m just paranoid. Can I pk from week 2-3 to the last 10 days from harvest ?Week 8

Enough LST for an autoflower?I was wondering how much LST and how intense the LST on an auto should be? I heard you shouldn't stress autos too much, that's why I'm extra careful and wanted to ask. (And yes I know it's overwatered, I'm letting it dry out at the moment)Techniques. LST

Will this tape repair a broken stem?Should I re-wrap this broken stem? Bent with too much pressure and there was a snap, though not completely severed. I applied two or three layers of duct tape, not sure if the constant pull of ties will allow it to heal and repair. When should I take the tape off?1y ago

What Should I Do?I'm planning on swazzing this next week and was wondering if maybe I should bend those long ass shoots to fall on my ring when I do? In my head it would even the canopy and get more exposure in the same. Am I wrong? Should I do it or just swazz and go? Any input would be greatly!Techniques. LST

!! OUTDOOR !! || LST on AUTOsNever had a satisfying LST when growing Autos outdoor, my idea is that suboptimal conditions of outdoor enviroment lead to slowed veg (compared to indoor) and low stretch. Maybe letting them grow without training in the end leads to bigger yield. What's your idea/experience?Buds. Too few

I want to learn more about LST (low stress training) tecnicI never done it before, but I’m sure it will improve my yield, maximizing resources, mainly light watts. Shall I start by bending the main cola, is it better for the shape of this plant? (+Speed auto from Sweet Seeds). Thank you 🙏 in advance for any insights.Week 1
