This is some advice I got from another forum:

Yes you can take a clone from a flowering plant but it takes upto 4 weeks for it to revert back to veg and it is no worth it. But yes you can.

Is this true? The only reason I want to clone is cuz I don't want to wait to germinate and start from scratch with the summer solstice coming to an end. Gotta take advantage of the outdoor grow season now.

What should I do at this point?

I tried germinating the only remaining seeds I had that were from good batches but none of them wanted to take. I used the wet paper towel method in a plastic bag. All 4 were failures so at this point I don't know what to do.
Delta.9 Reviewed by Delta.9 on . Can I Clone from a Flowering Plant? I should've thought about doing this earlier but I can't change the past. I have a plant about 4 weeks into flowering and am curious if I clone it still? One of the lower branches isn't really flowering well but is still alive. I was curious if I try to clone it, would it revert back to vegetating and be able to grow well. What does everyone think? Rating: 5
