or we could just help him cause its a forum. get som fox farm big bloom and tiger bloom for flowering. use molasses about 1 tbsp per gallon. what lights are you using now?
first of all, big buds to him may be gigantic to us or very small.. what size are you getting now.. usually a plant not done right doesn't give good/thick buds..if we could see what or if you've been doing wrong then we could help you. i.e. we need pics
What is your system/setup? That might be part of the reason you may not be getting as large of buds as you would like so tweaking that might be a place to start. What is your lighting like? What fertilizers/nutrients do you use? What all can you tell us that might then lest us see places where you can make improvements that will result in bigger buds.
 
That or just order genetics known for being very heavy producers and hope for the best.
Ya, its all about the fert, light and strain. If the your growing a strong sativa its most likely not going to produce even close to as much as a strong indica just because the buds are so much denser with the indica's. There are some sativa's that will get dense buds like Arjan's haze and im sure a few others not many. Big bud is notorious for huge buds....that's a good strian to go with if you want huge nuggets. Then we get to the light. I have used CFL's for years, an im not trying to dis on it but if you got the money invest in a HPS with a digital ballast so your electric don't sky rocket. Then the fert's, i started out with Fox Farm nute's and worked my way up to some others like Humboldt county nute's. Fertilizing your plants more than the recommended your plants will not get your plants bigger. Less is better. You don't want to over fert.>>>> At the end of flowering cycle at about 2 1/2 wks left i hit them up with a finishing nute called Gravity, this is one one the only ways to really increase the size of your buds other than just simply keeping your temp and humidity perfect. If the plant is nnot stressed at all its whole life not only will you have some nice size buds but the wait wont be as long. DIF is also a technique i read in high times a few years back that keeps the internodes real close together therefore getting real compressed buds. What it said to do all summed up is keeping the temp higher at night than the day. >>>>>Like that one guy said though you really got to READ READ READ I love this time of year!
I would recomend getting the strain choclope. Big bud is great huge buds but the smoke is ok. not that great. I would go for chocolope big yielder and it smells amazzing and tastes great and its a pretty good smoke too
Dude, people are trying to help you out here and all you can do is leave crap, very short reply's to the questions asked, you wont get bigger buds that way.
I suggest you read, read and read, you can never do too much research, and also, if you are growing outside i would post you thread in the outdoor growing , because that is the outdoor growing part of the forum and you would peobally get more help.
