Phototropism vs gravitropism...

Anyone with experience growing vertically can tell me why my plants seem to grow upwards as soon as I transplant into my vertical system.

They have 1100 ppfd at the canopy it’s not like they have lack of light.
Whatcha got there for lighting with the multi-cob per heat sink?

genetic memory. the plant isn't stupid. it knows if it grew sideways it would flop quick. isn't that the whole point of vertical? hack genetic memory.
I’ve seen vertical grows where they don’t do this though. Whole point of vertical is to get more usable space... if they won’t grow towards the light we aren’t really gaining any usable space

theres a black wire holding them back and its SOG

Where is this black wire holding them towards the lights lol? Mine is also aiming to be a sog

The only black wire visible is tied to the pipe holding the plants. That wire could only physically pull them away from the lights not towards the lights and they are still pointing more towards the lights than mine. That’s where my confusion is coming from

agreed, looks like the first pic is seeds, second is clones, otherwise both wanting to head up.
Yeah I have seeds this run round. Maybe it’s just me but I don’t see how seed or clone would make a difference unless it’s in the pheno selection.

I wish I had a photo of last run round to explain what I mean. If I started a seed or clone straight into this system it grows directly into the pot above.

I’ll read through that link now cheers

Hi guys, and I hope you don’t object to my chiming in unscientifically. I grow untopped plants on the floor, with a light above the horizon at a slight angle simulating 10a or 2p, at 24”/60cm distance. Sometimes two lights but I like to keep cost down. There is no ‘canopy’ and the plants seem to love it. I’m not averse to work, only extra work
