Theres a debate going on under Strains & Seeds on wether this site is a scam or not. The admin to the site is obviously from turkey and may I remind you people in turkey are MOSTLY assholes and will rip ya off, some of them wont and to them I thank.

If your capable to revegg your plant and hermi it so that you can collect seeds from it and have some more of your Triple X strain.

If you reveg it will most likely cause the plant to stress enough that it will turn hermie, either that or you can majorly heatstress it and it will become hermi.
