Here 70 hrs from the last photo. These plants are 6 days into flowering. I dropped the grow nutrient and bumped up the flowering nutrients. 300 ppm max with every watering.
Never use the "first rain" off the roof. Allow the rain to wash off the roof before collection. Always use an EC meter to check the ppm of the rainwater before harvesting. If the water is over 17 ppm it may have a few impurities. After using rainwater for over 60 years I'm still here without any problems. That goes for my vegetables too, because they get rainwater too. Every year since I was born the veggie gardens got rained on without any toxic waste. I'm over 66 now and still eating and vaping plants that get rainwater.I have heard that the quality of the rainwater also depends on the way it traveled before being collected. If it runs over roofing felt or other bituminous board / tiles the water is not fit for healthy consumption anymore.
Makes sense in my eyes.
Makes sense, however, if you read the above posts I'm not using rainwater, I'm using RO water. Rain water is mostly for people that can't get RO water. Its the poor man's RO.I am surprised by the argument "I have allways done it this way and I'm still well". Living next to a busy intersection in a large city is unhealthy even though one dosen't necesseraly have to show signs of deteriorating health.
And taking ppm reading as a safeguard Afaiu some carcinogenic substances need not be present in larger quanteties to be hazardous...
Kudos, I guess you don't eat vegetables either. Show me your best plants so I will know what you are talking about. You show up with 30 posts and act like you have some super knowledge about growing. The truth be known the only plants I've seen from your grows are nothing to brag about. As a matter of fact, the plant I saw looks really bad and will fail soon. Untell you try something first you can't criticize it without being stupid. Because anyone that tells others how to do something before they have ever done it is a hypocrite.Hey
"Let me ask you is it safe to eat vegetables that get rained on? Because I 've been eating outdoor-grown vegetables for about the same amount of time. Sometimes I get a Ton of rain in the Summer in my gardens."
Well that's great, kudos!
What are we talking about now?
Afair this started as a rant on how great rain water is for watering your cannabis plants.
I want to warn people about the rain water collected from running off of bitumius roof coverings.
I have no idea what tangent you are on now.
Nice plants you have thanks for sharingTake care Creeperpark
All the best!
There are many ways to harvest rainwater without having contact with toxic roofs. If you lay a clean tarp or greenhouse plastic over a harvest area you can harvest pure rain. Placing many collection containers can catch rain out of the air without contacting anything. Then after the rain is over dump all the collection into one big rez. for storage. Rainwater is liquid Gold friends.
