any advice on how to maximise my yeild will b much apreciated. i have spent well in excess of £10,000 on equiptment and need to see a big return please help

i have had small grows before but moving up in the world now

and 1oz sells for £200 wer i live any guesses on my return?????

for 250 plants 15 to 20 years lol.......just remember greed gets people caught.....

a bunch of nugs.

well i dont know your currency but i would say with canna ive heard of people yielding 3-5ounces per plant but this also depends on the strain you are growing... so take 3 and multiply it by 250(as long as they are all female).

250 x 3 = 750 ounces

750 ounces x 28grams per ounce = 21,000 grams

bro i hope its legal or legit.... cause thats going to be hard to conceal and keep stealth. its gonna be extremely stiny too when flowering. and biggups on using Canna Nutrients... thats what i use

that is way more work than you think . You couldn't keep this all to yourself.
