they stretch in 12/12 and u may have seen most of it already happen. that's a nice height. when the buds are heavy and ripe you may need to stake so be prepared for that.
Speaking in general terms, it sounds like they're about the perfect height. The majority of the 'stretch' should be wrapping up into week 3, so as long as its managable by you, should be fine.
im right dummies question... may need to stake??? u mean put them up against a bit of bamboo or sumthing like that??? or get sum netting so they dont topple.. 1 is leaning a bit ..
Yup something to support them. Either bamboo stakes or a screen across the canopy that you 'poke' the buds up through, you can also make a trellis system. How long did you veg them for from seed or clone?
done from seed .germinated 6 got 5...... started with them in little 3"pots transplanted after about id say 10 days in to 5 litre pots. where i veged them under a 250 envirolight for about 2 weeks . then put them under my 600 dual spec since,,,.they are now 3 weeks in 2 flower stage..
