its a big jump at least for me however there is one good thing about hydro and thats not having to worry about getting rid of all that dam soil each time. i might look into hydro a bit more though.
i called the store that sold me the soil and nutes and he did appologise as he sent me the wrong nutes and the wrong soil but that was because he got 3 orders mixed up thats how i ended up with the 1L bottle of BigBud for free. when i mentioned about the extra BigBud bottle he said for all the trouble you can keep it for free and also it is very posible to get the nutes to work quite happily with canna coco. he said the reason that the test plant has gone yellow is most likely because of nute lock and that i should let it dry out and then water it with just pure water then start feeding it half solution until its more of an adult then change to full solution.

hmm how many could i grow in a Bud Box size 100cm by 100cm and 180cm high if i was doing it as hydroponically? i hear they grow a lot faster and yeald can be quite a lot more.
