Vertical setup possible issue

I’ve just finished building a vertical system using 6 inch pvc pipe. A sort of NFT system with plants stacked on top of each other.

I was expecting the plants to grow at around a 45 degree angle towards the vertical lights..

However it looks to me like the clones I placed in the netpots have suddenly turned directly upwards and are growing into each other.

How do people avoid this?

You just have to push them a little inward. Pics please.

What is your light source?

If you want more phototropic response, you'll need lighting with more blue. HPS won't cut it.

Sorry for delay here’s a photo

Par meter has me at average 700ppfd 60cm from my lights it’s a custom cob rig I made.

They seem to be turning directly up in the direction of gravity.

How can I get them to face the lights?

Found this online very similar to mine.

But mine for some reason are growing up

Yeah this is definitely gonna cause me some
Problems they are growing directly up for some reason.

Anyone got any ideas about this?

Sorry I dont have any advice to help you out...I was just curious as to see what the rest of your set up looks like? Your hydro system in particular

The photo I’ve shown is my hydro system not much more to see really.
Just more and more stacks of pipe like that. I have rainbird sprinklers at the top of the pipes spraying oxygenated Water down the pipes and it falls back into the water res underneath

I’m quite screwed atm though as they are starting to enter faster veg growth and nothing I do will stop them growing against gravity.

It’s like plants are programmed to grow against gravity and not towards light which we know is not true...

Do you have any ideas about this? I’ve pushed them down as far as I can but the tips still seem to then turn upwards

Your lights must not be powerful enough to cause positive phototropism. Here is a pic of one of my older grows showing that response, but they are still growing upwards. My plants are tied back to a screen, they still lean toward the light.

Do you think it's too late into flower to try and get em bent like you would if you was super cropping?

My lights are 30w per sq ft with 50% efficiency par meter puts 700ppfd at the canopy.
Nodes are so tight. I think it could be because I designed my system so that I could have the lights far away from the “pots”

Currently the lights are 90cm from the canopy but still produce 700ppfd that far away.

I will veg my clones longer in a veg room next time to make them taller and that may help. It’s the only thing I can think of

Anyone got any idea on how I can train these plants to increase yield?

They are getting 800ppfd at the canopy but are only very very slightly leaning towards the light

They are growing very slightly on an angle but nowhere near as much as I’d like them to be.

Really like the system!
Do you plan to scrog these? That's the route I'd go!
If you had the downpipe running at a 45° instead of vertically and angled ur light the same in a tiered style u would get an increase in canopy size and the plants wldnt grow into each other....
I'd think about wrapping the pipework in something white as well cld help!

I didn’t plan to Scrog I was hoping to sog them but with them not growing outwards towards the light I’ve just ended up with a mass of huge fan leaves I’ve just trimmed thousands of fan leaves and all the bud sites are bright yellow from not getting light.

I hope they recover.

Im thinking if i switch my strain to a single cola strain like chronic or maybe blue dream and flower after 2 week veg and let them stretch in my normal horizontal veg room. I’ll move them to this flower room after stretch and hopefully they will already be facing forward toward the light and won’t change direction

Rent pics ?
