How much longer?

White Widow at about 60 days flower under 6-bulb T-5.

How much longer?

Humina humina humina!.. Nice work. I would say about two more weeks as I grow myself. You could pic them now but the THC level should be optimal in about 14 days. Look close at the white hairs. When the majority of the hairs about 70 to 75 % of them should be amber meaning starting to turn red. Not all the way red. I see some red hairs they are in a small amount compared to the amount of hairs.

what seed company's white widow (knock off) is this?

Looks great, it is really up to you at this point. The normal answer is of course go buy a magnifier (30x) and look at the trich's and decide how amber you want them. Everyone has their own way of telling but you aren't going to ruin anything if you take it down today even, most of us would let it go a bit longer, but depends on what you are looking for in your high.

When the pistils start retreating back into the calyx and the calyx swells into false seed pods, the flower will be at its heaviest and near its peak potency.

I agree. Using a magnifier is really the only way to get a precise read, and you really don't want to ruin a great grow like this one. I usually leave them longer too, for the more stony high.

no thats not what i mean, it is white widow its just not the original genetics

Thanks for the info its only my second grow.

Where's the best place to get Martian mean green seeds,and actually get them?

well it all depends were ur from (uk,us) and there hard seeds to get hold of as well

I thought it originated as white shark from greenhouse seeds co. LoL. Specifically Arjan The owner stated that in 1989 his white shark seed recipe was stollen and turned into white widow.
