In hydroponics if you use a commercial flusher like the one GH has it flushes in about 4 dayâ??s. When I flush with that I watch the trichomes once I see about 10% of them Amber I run my flush. I can hold them for up to 7 dayâ??s with out having any yellowing but I do trim my big fan leaves the last week to ten dayâ??s so the buds get more light to finish. And you can also extend the dark time at finish too by going 10 on 14 off the last week or so. The extra dark is supposed to help the trichomes grow larger. Itâ??s hard to tell when every time you look at them you have a buzz anyway but they look larger.

The fun of this is to learn, experiment, and have fun. Keep good notes and play around from time to time trying something different on one plant out of your bunch. You should have one control and one play plant with each grow. You will learn more that way and have more fun too.

I think that answered your question.
Zandor Reviewed by Zandor on . Zandor.....trichome/flush question I wasn't that clear on redvettes thread there about the whole flush timing thing.let me get this straight... I use GH Floranova grow/bloom so I can't just omit Nitrogen. When to flush.... Do I first check the look of the trichomes? Is a certain trichome "look" the message to begin flushing..or.... do you begin to look at the trichomes AFTER you've begun to flush????? flush to check trichs? or check trichs to know when to flush?
