I have 8 white widow under 600watt HPS, they are 43 days since I flip to 12/12. The average size of the main cola is 6 inches. All the side buds are from 1-3 inches.
Are these going to get longer or thicker? Do you count flowering time from when you switched 12/12 or when you see the first flower?
Yes, like the guy above said they swell in the last 2 weeks. These look to be 63 to 75 day strain. I count from the day they switch lighting cycle. I would suggest you to leave on the fan leaves on next time. My buds grow better, fuller and bigger with the fan leaves left on. Just tuck them in or remove a few. Your 600 watt can penetrate deep into the foliage.
Count both ways....I now grow indoors...
If you were growing outside in nature, you'd count from first signs of bud...
I count from first sign of bud [for my plants] it was six days after switch...
56 days from first sign of bud I had exactly 8 weeks/56 days...I then had first sign of amber tric's...
They will expand...
Sorry, I have absolutely no idea of the strain, bag seed.
I judge harvest time by the trich colour and by how much the calyxs have swollen. I switched to 12/12 in the beginning of Jan, so it'll be 10 or 11 weeks total.
BTW - I don't switch to flowering nutes, till I see the first little buds start.
