Glad everything is going much better. Don't mind helping at all bro that's what we're here for.

Plants siting in runoff can cause slow growth so it's a good thing fixing that problem. Since those roots are at the bottom already your gonna want to transplant soon. Don't let them girls get root bound. Go ahead and fully water those girls that way when the medium starts to dry out the roots will stretch towards the bottom for water.

Thinking of getting one of those Hortilux bulbs. I know a site where you can get then cheap. Not dirt cheap tho lol but let me know how your bulb does. I like vegging with HPS as you get a lil more stretch with it.

Won't be long before you start getting down to a few ladies. I hope you find something you really like
These are my 2 experimental pot sizes... there won't be any transplanting!
And these are all Fem seeds too...

They've been on 12/12 since day #1. Going for the crammed in SOG single cola's. 16 plants per sq/ft with 3" pots and 9 per sq/ft with the 4".
My goal for this experiment is to find a pot size and strain that is capable of yielding no less than 4 oz per sq/ft. This goal sounds crazy and maybe it is. But I'm going for it.

I don't think that's a bad goal to shoot for. It's not outrageous so it can be done. I believe with the right strain either size pot should be able to produce that amount of dry herb. I'm rooting for you bro and don't mind me I had a stoner moment lol. Title clearly states what you doin :lol:

i cant believe those are from seed, you mean you never let them veg at all. wow...
Well...I suppose the are technically vegging but they have been on 12/12 since they sprouted. They are definitely not where I expected them to be by now. I was expecting to see my 1st pistol by day 20 or so but that certainly is not going to happen. I will blame that on myself of course.

Edit: I think wcharles was actually mocking me...lol. That's okay though.

Day 20 from seed coming out of the ground? from the ground you're prolly looking at day 35-40. Factor in 7-10 days for seedling state, then about 30 to show a pistil IME.

The whole lot looks absolutely great though. Keep it up :)

There's some great 12/12 FS grows around this site, this is shaping up to be a great one.

Thanks for your feedback and for just being here!
1 to 1.5 foot tall is kind of what I was hoping/expecting but since this is my 1st time I don't really know. Del6666 laid the ground work that inspired this so I'm just following in his footsteps with my own personal little tweaks.

Regarding the age of my plants...you bring up a very good point. I was unsure how to report age so what I went with was average time it took for seedlings to actually sprout after I transplanted the 1" x 1" rockwool cubes into the Coco. So you are right, this ended up averaging about 8 days which I am not including. So technically, these girls are more like 24 days old from the time I opened the seed packs.

The 20 day estimate came from del...that was his reported average.

Different strains bro. Some will sex quick some take a while. Your doing great bro just keep doing what your doing and I say in a few days you should be able to give a 1/3 strength feed and sex could show by then too but they will show soon

Interesting thread! Don't worry about over watering the coco substrate. You can't overwater it! I watered with run-of four times a day with no ill effects. Think it's good advise though, to not let them sit in drainage pans.. They grow very slow in the beginning when grown 12/12 from seed, but soon you will have a jungle in there I believe. Best of luck! I'll keep watching the show!

I have much personal interest in this thread since I'm doing something similar. I jammed 17 3x3 pots n a grow cabinet, 4,65 feet2. Unfortunately the chinese led lights were advertise with a very misleading wattage, which left me on the low side on l/feet2. I've harvested more than half of them with about 5-12 grams each, but the remaining ones are bigger than that. My next grow will have HID intensity led light so that will be different!

I'd say that your biggest enemy at this point is stretch. If your plants get to tall and lanky they will start to shade each other and the higher ratio of fare red to red down in the foliage will cause both side shoots and tops take of.. More so with the HPS than with the MH.

To avoid this you want your light to hang as close as possible without burning the plants. (this will shorten the internode distance) Use a small oscillating fan that blows above your plants ant makes them sway gently. (this will give them sturdier stems and also help with node length.

MInimize heat difference between night and day. A small negative diff is optimal. (slightly cooler light-periods than dark periods.

I do think that higher EC PPM of nutes will keep them shorter. (more eating less drinking) This upper limit will be low for you since you have so many strains.. If i were you a would try with half strength next watering, than work yourself upwards till you see some nute burn in your pickier plants, and than, either go down from there ,or let the pussies suffer a bit. If you look at Dels plants they always looks pretty overfed, people actually mocked him for this.

Keeping plants short in Coco isn't easy! if you find it difficult, i do believe that you'd benefit from sacrificing a few of your lankier or underdeveloped plants to let the other plants reach there full potential.. I think you would benefit from going perpetual and starting in very small pots and than replanting the best looking ones, thus utilizing the ligh more effiviently... This would also help with high humidity and mold in the end of flowering..

Do you know of a link where Del shows his hole garden in any of his threads? or if he ever presented any numbers of gr/kW... Please link if you can!

Del's giant thread is here:

Great advice and suggestions...I really appreciate it!

Against other advice I received, I have switched back to the MH and will just play it by ear regarding when to switch. My temps are staying very consistent now that fall as arrived. 73 with lights on and 68 at night are the two high.low extremes. RH is also very consistent in the mid 40's and I expect it will drop even a little lower. I have a 2nd dehumidifier on standby just in case I need it.

Regarding the crowding factor...yes I anticipate this being a problem. I intend to remove all side branching and do selective defoliating as needed.

I have a fan on them 24 hours...I'll get a picture in today's update.

Thanks for the link! I've probably read parts of it while googling stuff, but never seen his garden as a hole. (always thought that he gave his plants plenty of space in order to let them develop to so impressive plants.

It seam's as you have everything under control man! I do understand that you probably have done your research, and have some experience, even if it's 20 years old! Maybe your higher light intensity will help you with the crowding factor.. I think that going with MH until post stretch of plants will help a lot. Of course that time window will be pretty big because of the different strains you have.

I did a lot of de-leafing on my biggest plants, And I have the feeling that it slowed them down, but also delayed flowering, and that they eventually got almost as big as they would have done anyway.. (This is my gut feeling and I have no way to confirm it scientifically)

Have you read this?
http://www.nomercyseeds.eu/en/growinfo/12-12-system.htm

I would like to try his santa maria, or no mercy special.. But hate to waste times on males. Santa maria is so in-bread that you probably would get away with pretty uniform selfed seeds. Have you considered to try it. Making your own female seeds would save you some money, and probably be very fun to!

I have not read that but I will right now.

I have never removed fan leaves (at least that I can remember) so I will have to not only be careful but will need to do some controlled tests. Perhaps I will do no defoliating on some, minor on some and major on some and just log the results.

Here is another grower that I studied and his results are undeniable:
http://www.420magazine.com/forums/completed-journals/149813-2-liter-hempy-sog-4.html
He is pretty dialed in and defoliates at day 21 and again at day 45 if I memory serves.

2L bottles are what...4 or 4.5 inches wide? He has them side by side...no spacing.

I have read about making my own Fem seeds and it is certainly worth a try. Depending on how this experiment goes, I was planning on picking the best 2 or 3 strains and then purchasing regular seeds from Attitude and simply grow these out and pick what appears to to be the best male and female from each strain and interbreed to create my own seed stock.
