A question for anyone in the know......?
Im off to London on Wednesday for 5 days and these H magnifica buds are looking pretty good....the question being it looks like they may ( or may not ) open in the next few days. As its a first time bloomer for me, I have no idea how large these buds might continue to grow to... Any ideas as to how long they should stay open if they decide to open after wednesday? Gonna be a real shame to miss the show.
ps, thats dust on the leaves from building work, not mould . ...these hairy leaves arent as easy to hose down...:))
