Hey folks I saw someone post and adjusted VPD chart for growing with LEDs. Searched the forum to no avail and my google-fu wasn't good enough. Anyone got the image for me?

So I think we're all aware that a lot of bullshit broscience gets spewed about growing - from the blurple schtick to sticking copper through stems. I read some stuff today that's just been the straw on the camel's back and I'd love to share it with RIU. Some pollen chucker is trying to sell...

Hey folks I bought a cheap luxmeter in hope of dialing in my lighting a little better. I'm using Samsung 80cri 3500k strips. Is there any way to convert this to ppfd or something else where I can get an indication if I'm using enough light?

Pretty simple, looking for any journals where I can see a plant and its S1 expressions. Done some digging but can't seem to find anywhere I can see the parents as well.

I can't really figure this out. My fan had shifted and was blowing directly at the plant from pretty close, and in the last day a couple leaves have gone from perfect, to this. I can't really tell if it's thrips or something else, but I'm around 3 weeks into flower so limited in terms of what I...

Hey folks I'm looking at saving on my electricity bill, I was wondering if there would be any benefit to running a completely different light cycle. 1h on, 1h off for the whole day. Anyone ever experimented with his?

Hey folks I can't seem to figure out what is happening with my clones. They're about 2-3 weeks old all have a tap root that's popped out the rockwool already. I'm hoping that they've got too much humidity, as I have them together with my seeds under a dome. Can anyone confirm this? I gave them...

Hi folks Are there any benefits or detriments to sealing the root zone? I'd been growing in a homebrew mix up of rockwool blocks on a bed of leca/hydroton in a 5L ice cream container. I fashioned some panda film covers for the containers and that got me wondering, would the roots benefit from a...

Been considering getting some of these but i can't seem to find any grow or smoke logs online. Anyone got experience with them? Mostly interested in their White Widow.

I received a clone from a generous local grower I bought a grow tent from, but it seems to have some kind of mildew or mould on it. Before I try to treat it, can anyone confirm if this is white powdery mildew? Bonus Q is about this baby. New growth is yellow but eventually turns green. Not...

Hi folks I started my first grow last week. Here in South Africa, a court ruled that private use being illegal was against the constitution and in so, it's a technicality that has allowed us 1 plant per household. I, however, have a dickish landlord and will be growing in a 750x550x2200...

Hopefully, my topic gives you a good idea of what I'm trying to figure out. I've found a pretty great store that sells some basic hydro stuff local to me. They have super cheap nutrients and I have been trying to appropriate them to use for some great bud. My main source has been this vv...
