Good God that is a lot of plant.

I'm not sure of your experience level. Have you flowered plants before or is this your first grow? Do you know for sure all those plants are female? (my apologies if you do have experience...)

My first suggestion would be to read this: http://boards.cannabis.com/advanced-...ml#post1546321

Take enough clones so that you don't wipe yourself out...then...in my honest opinion...put those huge ladies to rest. It's very sad. but it seems as though those plants have just gotten out of hand for your setup. (is that your whole setup?) If you are doing just a personal grow, then one mother plant should be enough. if you have multiple strains in there, then obviously you'd want one mother per strain.

But yeah, i'd suggest taking clones to make a new mother using the bonsai method above.

If you don't want to kill the big momma's off (like none of us ever do...)and if you have enough experience and feel comfortable doing so...try some experiments. Cut a decent size branch off (much bigger than the average clones)...see if you can get that to root some how...then throw it into flower...i dunno...just have fun with it.

good luck.
