Hey @Calyxander welcome to the X18 Outcrossess Thread , you could continue your updates on this thread or maybe start another for the ibl X18 only..?!
Anyway those are pretty plants you have there, did you note the stretch, was it double or more.?
I've noticed the three different outcross ( 4 girls in total,) i have, - all stretched from about 12 cm ish to all over two feet, but they're all just big Colas at between (since showing sex) 25/31 days in, I kept a 88g13/HP male and dusted a couple of small buds on the female 1888' , also snapped a small branch at the bottom of same plant, so I stuck it in dirt n it seems to have rooted .. the Stardawg cross is stinky , I'll be finishing these off under my cobs and my new rig..
Coz I'm using my phone i can't see in what order these pics will show, so one is the 1888, 1 x Stardawg, two Nigerian Hazes plus a Kimbo Kush from @LED_Seedz ( 2nd pic) ..
Happy growing guys,
