What do you think you mean for how long to harvest

It really comes down to the strain as each plant varies. What you should be looking for is trichomes that are milky and a few amber (goldish) in colour. In the pictures you have posted they look clear, almost completely transparent which means its the first stage of the trichome development. Each stage gives different effects and usually growers have their personal preferences on the ratio of milky and amber trichomes (like 80% milky and 20% amber, etc). I'm guessing these pictures are from your Bubble kush Automatic dairy and by the look of it in my opinion you should give it 3-4 weeks more to reach a good potency. An other way to tell is by looking at the pistils (the 2 long hair like structures from each bud) and seeing if they dry up and turn orange. Hope this has helped :) Patients is key for a good final product.

Hey buddy, How long are they in flowering stage.I would say they will take around 8 to 10 weeks from the start of flowering circle.The proper way is when those clear crystal trichomes turn into 70/80% milky and 20/30% amber colour, that’s will be your time to harvest.Good luck and happy growing... ✌️
