    So im having this white rhhino, its 8 week into 12/12 light, the trichs are still mostly clear. I want to harvest it at 9 weeks. What to expect in the next week? Do the trichs will get cloudy with some amber in 7 days?

    oh shit, those are looking sexy bruh
    I got a couple of questions for you that i hope u dnt mind answering.
    How long did you veg for?
    How tall are your plants now?
    Did you use any techniques?
    What sort of nutes and soil have you used?

    Like most of the White strains such as White Widow, White Castle and White Rhino are the longer flowering period plants. I would wait until week 10 or 11 to harvest, the last weeks are crucial in getting that sucker to put out every last bit of its juices.

    The plant looks very healthy and swollen, looks very nice indeed and let us know how it goes.

    Im feeding with products from biobizz (biogrow and biobloom)

    Veged for 6 weeks
    I have just 2 plant from green house company, the white rhino is 55cm and the A.M.S strain plant is 90 cm(havent fimmed or toped)
    I used the F.I.M. tehnique/training for the white rhino you se in those pics, thats why so many colars
    I have used soil in mix with perlite, soil wasnt nothing special, regular one.

    Yeh i know about the White Widow that it can go until week 11 because its a more sativa dominant but White Rhino its almost pure Indica so i think 11 weeks its to much for her, breeder say 8 weeks for comercial growers, 9 weks for full ripnes.

    Almost forgot to mention, i have used 250w, MH in veg and HPS in flower. More pics, first one its how w.r. looked at 2 weeks of flower(monster bush, f.i.m. tehnique is very good) and second pic at 8 weeks :

    White Widow strains and White Rhino strains are not long flowering plants. When you get 90 day and 135 day 150 day flowering strains, those are long flowering strains.

    In this case it sort of depends on which knockoff White Rhino is being grown. They can run from about 56 days to 70 days. The original Cup winning White Rhino that was renamed Medicine Man is a 60 day strain.

    It might be helpful to know whose knockoff White Rhino is actually being grown before anyone suggest any certain total number of days or weeks they should go.

    There is another example of what happens when dealing with information about knockoff strains. Depending on whose White Widow is grown the flowering period can range from 55 days to 75 days ... and some are mostly indica and some are mostly sativa.

    The original Cup winning White Widow that was renamed Black Widow is a 70 day strain.

    When asking or advising about knockoff strains it is always important to mention which breeder's knockoff is being asked about or information given is for which breeder's knockoff. If not the chances are fairly great that misinformation will be given/received.

    Hi Brick
    Many times when i see your post i read them and i like and learn from them, you have a great knowledge and i apreciate your help on this forum.
    As for the White Rhino, i have the seeds from green house company. In your opinion, when i should harvest? 9 weeks it will be enough, now at 8 weeks i see more clear than cloudy trichs.
    I have read feew of your post wehere you say that most people are worng when they harvest at 50% amber as the peak levelsof thc are degradin in cbn.

    On many forums i have read that thc is degrading and forming cbd not cbn, but that could be wrong as cbd levels are genetic and strain dependent, right? This is my first grow and when started i had in mind that i will harvest when more trich are amber because i want the medecinal effects of the cbd(i have anxiety disorders and sleep disorder) but now after reading few posts of yours i learned that i will cut from potency of the plant if wait to long for harvest and that amber trich dosent mean higher cbd, just higher cbn.
    So whats your opinion on this strain from green house? Should be enough 9 weeks for good medicinal effects?

    You are welcome and thanks for the rep.

    It is impossible to predict if it will change enough in one more week. You will just have to watch and wait.

    Yep, that is how it works. Some people talk about wanting potent pot and smoking potent pot but when many harvest at peak potency it is too much for them, it is too potent, and they wrongly blame it on harvesting too early when it is a combination of them having picked the wrong strain that does not give them the body stone/couch-lock body buzz they hoped for so to get what seems like more of it they throw away THC, they lower the potency level, they tone down the THC in the strain and because 'The Dutch Masters' have pretty much bred CBD out of modern strains. They have bred for high THC levels, for true potency and potency only and not for medicinal properties.

    That is what a lot of people believe, but then people believe a lot of things that are incorrect when it comes to cannabis plants and how to grow them.



    The capitate-stalked glandular trichome changes color as it matures. Newly formed and immature glands are clear, glands reaching optimum THC production are cloudy or milky and amber trichomes have already passed their peak. By looking at the trichomes you can also determine the best time to harvest your plants. When most trichomes have gone cloudy and a few amber ones have appeared, the plant is at its peak.

    CBD is genetic and is not increased trough THC degradation, though CBN is and since CBD has been almost totally bred out of modern strains and even though CBN is not the same thing and does not do the same thing, because it mainly does effect the body couch-lock lovers who do not understand cannabinoids think they are increasing CBD levels by harvesting when there are more amber trichomes.

    Cannabinol is the primary degradation product of THC and increases in concentration with plant age. The concentration of this product in the bud is heavily dependent on the time of harvest. Harvesting the bud at a late stage also means that the concentration of CBN in relation to THC will be higher when compared to the peak of THC production.

    CBN content increases as THC degrades. It is only mildly psychoactive and can cause "fuzzy head", drowsiness, disorientation and sleepiness in the smoker, properties that can be considered unpleasant in nature compared to the clear high of the THC. Its affinity to the CB2 receptors is higher than for the CB1 receptor, meaning that it mostly affects the body.

    I am not a big Green House Seeds fan. If I wanted the genetics that won the Cup I would have purchased Medicine Man from Mr. Nice Seeds. But you can't set a date, a set number of days or weeks and say that is when you will harvest and be sure you will be harvesting at the best time. You have to go by trichome color.

    Green House Seeds White Rhino is said to be a 9 week strain but breeder claims are just somewhat close estimates of how long is needed. Everyone's setup is different and when grown in different conditions flowering times will vary. You may be fine at 63 days and it might take 69 days or a day or three more or less. Watch your trichomes closely and when there are around 5% to 10% amber you will be at peak potency.

    I would suggest if you are looking for actual medication that contains high CBD that in the future you Google medicinal marijuana sites and see what strains they suggest and who the breeder is and see if you can get one or more of those strains if you find what you have this time turns out to not be what you had hoped for, that or at least purchase Medicine Man next time.

    Brick, thank you very much for the read, for the graphic chart and of course for your time. Your posts helped me a lot to understand some things i have questioned nowadays about cannabis. I have found on the i-net a strain that its told to have 6.9 percent cbd, the name of the strain is cannatonic adn it have a ratio of 1:1 thc to cbd.

    Unfortunately, after this grow i dont know when i'll start to grow again, i cant grow all the time, i had this window for the firs grow and i had to do it. Cannatonic sounds a good medicinal plant that i would like to grow, of course i dont mind recreational strains(also growing now some a.m.s. plant from g.h.) but my main goal was for the medicinal purpose, those sever social anxiety's destroyed half of my life, i have searched something new to ease me.
    Thanks again Brick!!!

    The grow after this one will include some Cannatonic for me.... I need to find strains that help medically my conditions... pain relief is a major factor... when the grow is finished around end July will let you know how it goes.

    Thanks madcatter, dont forget about it please.

    just take a sample bud at 9 weeks , nuke it and puff it
    i start sampling at week 7 :)

    I think the percentage numbers for Cannatonic are being 'played with. Check out the difference in THC percentages between the breeder description and the test results. If Cannatonic has a 1 to 1 ratio of THC and CBD then if the breeder's THC information is accurate then the CBD ratio for Cannatonic should be 20% to 25% ... and it is not.

    Resin Seeds - Cannatonic
    Strain: Cannatonic
    Breeder: Resin Seeds
    Location: indoor, outdoor
    Type: indica/sativa
    Flowering: ~67 days
    Normal or female seeds.

    The best of both worlds, a phenotype selected from the hybrid cross between a female MK Ultra (F1) and the all time famous G13 Haze male. Grows like an Indica, smells like a Sativa and renders you... Cannatonic!

    Indica/Sativa: 50/50
    THC: 20-25%
    Flowering time Indoor: 9-10 weeks
    Harvesting time Outdoor: October
    Yield Indoor: 500 gr per m2
    Yield Outdoor: 250-400 gr per plant


    Either the breeder or the test lab has to be incorrect about THC levels or a very close to equal THC to CBD ratio.

    i am just wondering how you feel the FIM method worked for you compared to the one you didn't prune. I have a few white rhino from green house seeds and was debating on pruning after reading that they dont's respond well, but i dont know if they were talking about the usuall old school methods of leaving just the bottom 4 branches or what, cause it looks like you got a shitload of nice tight colas from FIM pruning yers. I would say after nine weeks u could harvest. waiting longer will get more amber and probably more weight but if u want a great stone with a little lift harvest at 9 weeks when they are cloudy. at least that is my opinion. i know green house says nine but keep in mind dirt usually takes longer than hydro, or so they say, and nine weeks is an estimate just like what they say yer gonna get in dry weight per square meter. well anyways, good luck!
