about 15 to 20 bucks at most grow shops.....they have a light on them....then check the trichomes daily.....when almost all are milkey...and some are amber you are ready.....plants will mature at different times....I just harvested 8 OG Kypronite plants and it took about 14 days between the 1st one and the last one to mature.....here is when I took them 10% clear...60% cloudy....30% amber....you will always have some clear...as the plant is still producing trichomes.....Now this is only my opinion....some want mostly all amber trichomes.....In my case the 10..20..70 works for me + I needed the space to move in the plants that were vegging in another room....into the flower room.

Good luck
weeddaddy50 Reviewed by weeddaddy50 on . MFing MITES are back! 5th week into flowering. Need to kill them fast. Mites are back! They were gone for a month. It's a 5th week in to a flowering. I am not spraying my ladies with anything, fuck no! It will ruin everything. I dumped about 2000 lady bugs on them yesterday and I'll water my plants with Azatrol on Sun. I have 2 No pest strips in the room I think I'll add 2 more and will turn off intake and exhaust fans for 12 hr at night. Do you think it will work? Any better idea how to kill them fast? Rating: 5
