EC formula troubleshooting
FuZzY619started grow question 5y ago
To get an EC value, I must multiply the ppm reading by 2 and divide by 1000. But my TDS tester gives me both microSiemens and ppm reading.. which measurement do I use to get the correct EC value, microSiemens or ppm?thank you in advance.

Like mouse said use the uS/cm value as it is the same as ec just a smaller measurement. Its like millimetre to centimetre or feet and inches . PPM can vary depending the device.

Can I change my autoflowers light cycle withou reducing their yield significantly?I am having humidity/mold problems and was thinking of changing the cycle so the grow goes off at noon ( currently it goes off at 1am and its winter and gets real cold with 88% humidity).
Even if I stress them, it would be better to not have mold than reducing the yield, right?Other. Mold

Flowering/Preflowering/Showing sex in Vegative Stage?Hey,
Today I noticed all my outdoor plants have pistils after being 3-5weeks outside. Is this normal and will they continue veg due to increasing days/temps? Also, could this be reversed with additional light? Currently in the 7th week of Spring with 14h light and 13h sunrise.

Advice for checking trichomes?Any advice for checking trichomes? I have a loupe but just purchased a digital microscope. Images look great, I can get really close up comfortably. Curious where on the plant one should look, multiple locations, etc. I think I’m shooting for 10-20% amber.Week 15

Did we start everything okay?I'm OCD #af and worry about EVERYTHING.
Is there anything we can be doing better? Light distance, germination tactics, water amounts with coco? Did we use too big of a cloth pot (I've been told 7-gallon is good, and I feel that what we have in a 10-gallon pot).Week 1

I got to harvest in 14 days: in order to have enough time to cure it before leaving home for 2 weeks (safety first: is a period of floods in here, I just can't take the risk). I had a pretty long vegetative stage but I'm gonna finish it at 13 weeks. Am I gonna ruin it it, right?

Knocking sound from my Oscillating AC Infinity fanI have an AC Infinity fan (Cloud 6 I think) and am surprised by how noisy it is. The blades turning are quiet enough but the oscillation function gives off a knocking sound which is not ideal for my guerrilla garden. Has anyone else had this issue ?

ZwiddetHey, it's me again, and unfortunately without a diary for the grow. (didn't have time) You can sadly see that with my ladies. The picture shows a Bloody Skunk autoflower in the second week of flowering. Is it a hermaphrodite? I can't remember the other grow, it could be normal.

When is the best time to harvest your plant?I know everyone has their own opinions on when to harvest. Is it better to have some amber trichomes or a lot? I have read that the more amber trichomes the stronger the effect that the smoke will have. It that true or just bullshit? 😎👌Week 8
