Question for experienced growers/support members of ILGM.
On info page for this strain it says average time to harvest is 56 days. Site also says 6-7 weeks from germination to pre-flower. Is it 56 days total from germination to harvest, or 6-7 weeks, then another 56 days? I personally was thinking about 11 weeks for this strain. I do not want to exceeed my harvest window, so if anyone could give me an idea of where I am with these plants, and a time frame to harvest, I would appreciate it! Thanks!


The 55 days you are referring to is the flowering time. Those times are averages and they can be sooner or later. It does not mean that it will be 56 day to harvest. The plant will continue to flower and mature at her own pace. It appears to have just have been flowering for around a couple weeks? When did she first start showing flowers? Autos will grow for the first couple to 3 weeks then generally start flowering then

Now this is the big question. Most breeders claim 7-9 weeks, with some even boasting seed to harvest in less. It would be fantastic if one could get 50g per plant after just 39 days, but lets face it, its totally unrealistic. A plant doesn’t grow any faster for having an auto gene, and the dwarf autos that will harvest in ultra quick times are just that: dwarfs and thus yield is limited by size.

Of the 15 or so different commercial strains I have tried, not one of any consequence finished in less than eleven weeks – and the best ones can take anything between 3 and 5 months. If you think about it, this is not surprising: most standard autos start showing their sex at around 21 -28 days (super autos not included) – if you add on a flowering time of 8 weeks (average flowering time for a indica) then you would be looking at 11 – 12 weeks.

And also remember that you’re dealing with mother nature and you can’t rush that she’ll be ready when she wants to be


They started showing signs of flower on week 3. I’m at week 5 now, so about 3 weeks. It’s only within the last 2 weeks that they have really started to flower though.

They seem on track to me.and lookin good
