weight useing dwc bubble bucket method.

don't let it get over 6.1 imo. 6 plants under a 400w is a tight squeeze. i do 2 plants, vegged for 28 days. they end up around 4-5 feet and yield a 1/4lb a piece.

 

penetration will become an issue later on into flower. can't say an estimated weight though, it depends on a lot of factors other than lights

 

Look up the relation between ph and the plants ability to absorbed the different nutriants. For example too low and it can still pull in some nuts but not others and vice versa.  People will often let the ph drift from a little to low to a little to high and so on. Or just stay on top of it and keep it at a nice balanced 5.6-5.8.  over 6.1 and it probably locks out important nutes for growth.

 

If the canopy is full and the plants are in good health under a 400w 8-12oz is about right. Obviously if you have problems it's going to reduce yield.

The number of plants doesn't really make any difference to yield. The more plants you have the smaller they have to be. Just make sure your canopy is full. Any light shining on the ground is wasted light

 

A gram per watt is a good result, I wouldn't say that's an average yield, but maybe the average of an experienced grower perhaps. Mind you a 400w HPS actually uses around 450 watts and when you factor in fans and pumps it's probably way over 500w. But then I don't know if you would count all used watts in total

ScrOGing when done correctly is a huge yield booster. It wastes very little light and allows you to veg longer in a smaller space.

 

Gorilla, attitude, herbie's, nirvana, single seed. You know, all the ones from banners and the whole seed bank section of these forums.

Don't Google some obscure shit and buy from Mikesreeferseeds.com or obviouslyshittyseedbank.net. and then complain on here.

As for banks I can't recommend attitude enough.

I bought from gorilla once and their site said it was free postage, when I paid it charged me. I emailed them 3 times about this and also wrote a note on the order itself and not one reply. They took two weeks to get my order to me.

My most recent attitude order took 21 hours! And they always give away free seeds

The seeds I got from gorilla were duds too, but obviously I can't blame them for that, only their customer care, it doesn't exist.

As for breeders, well, you get what you pay for really. Don't buy from feminised seeds. They state on their website all their seeds are guaranteed, and no questions asked. If you want to send the seeds back for any reason they will replace them. But their address isn't on their website, and after numerous emails asking for their postal address they still haven't replied.

Nirvana have great customer service but their seeds aren't exactly top shelf, but fairly priced.

Herbies seeds are good priced and free seeds included but I have never bought from them.

Dutch passion, sensi seeds, serious seeds, doggies nuts seeds, Dinafem, high quality, joint doctor are all great breeders

 

I've bought and grown. Ice-Nirvana, Pineapple Chunk-Herbies (currently growing at a friends, no journal), DurbanPoison-Herbies (current grow journal), and Heavyweight Fruit Punch-Herbies (I killed them all)

All super stealth and all got here on time.

 I have references of a ph chart that states 5.1-6.0 is all a acceptable range to grow hydroponic plants. 5.2-5.5 is optimum IMO
 
Hopefully I don't get another warning for this reference post since I think that's what my last one was for. I never really understood that as helping people is all I'm here for.

First time grower? Expect a couple oz hope for a lb. Also don't forget about the possibility of losing some. Kinda like hope for the best but expect the worse. This recurring yield question comes from the most anxious growers which are the ones to try to use too many additives with a inadequate environment and are most likely to harvest early, don't do any of those beginner mistakes.
