Thanks for all the comments, I do have a 30x Microscope, and have been watching the Trichomes on daily basis, most are now Landular Bulbous Trichomes, and are just starting to turn a little milky, I have now stoped the feed, and am using PH balanced water to help flush nuits from them, I will be harvesting on May 5th, as I reckon they will be just about right, besides I need to get them drying before I go on holidays, However I have 8 more in hydro tubs under fluro, which I intend to keep 4 as mothers, and flower the other 4, these are all cuttings from the original 3 plants, Although plant 1 turnrd out to be fem, it only has about a 10th the amount of trichomes as the the other 2, so will probably flower the cuttings from that, and keep the best ones asa the mothers. I will post some more pics before I chop them, and more when its dried. As far as smoking samples is concerned, I only took a couple of tiny buds from the bottom of the main stem, about an inch from the top of the soil! dried them for 30 seconds in the microwave and smoked them, they were a bit "tasty" lol but wow! damn strong, so I cant wait until all my hard work goes up in smoke!!!
