Yeah mine are 64-80cm from the perlite layer above the coco - 4 days since flip
Funny I thought yours were bigger, I think because mine are all Indica leaning and bushy they seem shorter.
I have 200cm too 5x5 to the light somit passes the inline and I will only lose 8-10cm for the ratchet blocks and hooks, at the bottom I lose say - dunno all in 60cm loss. 10cm top and bottom, 20cm pot, 20cm between light and plant tops.
Only 140cm to work with
Please! 120cm is enough
I’m not used to this tent malarkey!
