The only shark I have run was CBD shark and it barely stretched IIRC. However, no matter how tall she gets, you can always tie the plant back down if it gets too big. Plant bondage is a great thing to master.I’m getting ready to flip over but I may have let them get too big.
Sometimes black widow phenotypes can be stretchy.I had a medicine man pheno that almost tripled in size and I had to pull it early.
Just an approximation would be close enough.Hopefully only doubles in height.
