hi megaplant, i would agree with some of the others here, it looks like at least another 6 weeks before you would get a decent harvest. try getting some sort of feed for them, you can get organic feed that will not harm the enviroment (it will make it worth while - and can be cheap). if you are using the natural sun and growing indoors, then just keep it going, as long as they get at least 8/9 hours good sun, and no light from inside your house. i harvested an indoor plant at a window in late May once, so anything can be done. good luck.
