12/12 From Seed Experiment - 21 Strains

There are no discernible differences so far between plants in the 3" pots vs plants in the 4" pots. The height variations and lower branching (or lack thereof) are spread pretty evenly between the 2 pot sizes. Tallest plant is 17" and the average is 12".

Day 32 Update - Day 7 Flower

Today is the 1st day that I started less than once per day watering/feeding. Instead of watering right when lights came on I waited to water until 1 hour before lights off. I'm experimenting with letting the coco have a chance to dry out a little more. Early in the grow, I was unable to do this...presumably because the moisture that was present became too *hot* with the nutrients that were still present. This evening, to my surprise, the girls looked as if I had just fed them. Leaves were very perky. This gives me a few clues:
1) They perhaps were a little unhappy with being watered as often as they were
2) They are now capable of stronger nutes.

I began them on the Week 1 flowering feeding schedule one week ago and I started weak...20% strength. I increased the percentage with each feeding in increments of 5%.
Tonight I deviated from this and bumped the feed all the way up to 50%. Aside from the 2 clues listed above, the PPM's of the last feed was only in the low 400's if you exclude my tap water. At 50% strength, PPM was 725 including my water and 555 excluding it. Seems reasonable and possibly still on the weak side...we'll see.

Tonight I decided to pull some individual plants out to showcase some of the variations in growth patterns. Up until now, I've only been showing the stretchy ones so let's take a look at some others too now.

So far, the strains that are furthest along in flowering are Skunk #1, Northern Lights and Bubble Bomb.

Day 34 Update - Day 9 Flower

Girls are doing well. I'm pretty shocked at how tall they are getting. Taller than I want and certainly taller than I expected. If using the MH bulb has actually reduced the stretch then I cannot even imagine how tall they would be if I had started with the HPS. 50% strength suggested nute strength seems to be about right. I few plants have a tiny amount of burn on 1 or 2 tips so I feel like I'm probably right around the max. Managing the variance in height is a big challenge. I've run out of all of my extra pots that I've been using as risers so I have to come up with something new. Tallest plants are in the 23" to 25" range and most are in the 18" to 22" range. A few runts here and there.

Tomorrow we move into the tent. I've got all of my new ventilation gear and its time.

Enough jibber jabber...onto some pics!

This first picture is my new 720 CFM fan and 750 CFM Phresh filter. This has been serving as the primary means of odor control so far in the 17' x 13' room I built. It has a passive 6" intake but is otherwise *reasonably* air tight. Once the girls move into the tent, this will become my secondary odor control as the tent will have it's own.


This last shot shows the density of the underside. Not nearly as bad as I would have expected considering the size of the pots.
Still on the fence about defoliating. Now I'm leaning towards chopping all the lower stuff off on 50% of the group and compare the results. I just don't see anyway at all that this lower stuff is going to generate anything other than weak fluff that I simply am not interested in. I wish I knew where the top colas would officially begin.

Looking awesome as always bro nice new CFM setup

Thanks Sure hope the odor control is going to be on point. Think I'll switch over to my HPS bulb tomorrow too when I move into the tent.

Yeah that should be fine for oder control i got a smaller CFM setup and you can smell it when in the tent but outside nothing i had to seat in the tent for 6 hours trimming on the last grow was a pain in the ass but was a good reward and that's what it's all about at the end of the day

subbed... this is awesome!

As a guy who always swings for autoflowering girls, mainly of course due to the short grow time, I have desperately wanted to try photo plants on a 12/12 from seed schedule. i will be paying much attention and taking notes!

Glad to have you along for the ride! Feel free to post suggestions or ideas too. I usually ask questions on the updates to get feedback.

Cool grow.

hi can you tell me if im on the right track to rooted clones under 12/12 straight away .. i topped one and left the smaller girl alone .. im goin hps soon 250watt hopefull isit lookin ok tho ??

I'm no expert but those looks pretty good to me so far. The colors you're getting on the hairs is amazing!

this is my first grow and i have really no idea what im at does the bigger one look stretchy there about 4weeks into flower and yeah the pistols are nearly red.. proper red .. but it nowhere near harvest yet ..and thanks they smell pritty damn good too

Minor Update

I started the process of moving things into the tent this morning. Due to time restrictions I'm going to have to do this over a several day period.
Will be switching over to the HPS bulb very soon too.

Looking Excellent M8.

Love the evenness of the canopy. I am having to train a bit to maintain my canopy. Kinda like trying to contain an explosion in a paper bag, but I am trying...lol

Many Thanx for the update.

Peace and Great Grows

Thanks man...it's not as even as I want but it's hard! I can make it even and then 10 hours later it's all out of whack again.

Some of them have as many as 10 pots they are sitting in to bring them up to level. Also, in the white milk crate, see the foam board pieces that act as steps? That worked for about 2 days until the stretch started...lol. I'll come up with something.

Day 35 Update - Day 10 Flower

So today was the big day to move the girls into the 4'x4' tent. I have not hooked up ventilation or the filter yet but will soon. I also decided to switch out the MH bulb for the HPS. My theory on stretch reduction with the MH did not seem to pan out for me so might as well switch now. I did some minor defoliating on a few plants....removed the lower 1/3rd leaves and shoots...nothing to major or drastic. I intend to thoroughly document the defoliation techniques I attempt so we'll see!

Hello Hot,
You asked for a review of things that can change and the first is replant into larger containers for the growth that will happen in flower.
Most important to have a big root potential. As for the pruning the plants at this height should not stretch much more an will be heavy into bud production the next few weeks. Don't believe you need to cut anything off except a few very bottom branches that would rob the main colas of there food and weight. Actualy looking good from what I see.
Just repot them so they can have more root room.

If you get 3 gallon or 5 gallon grow bags or cloth pots like geopots or airpots you'll get a bigger yield. Especially if you lift the bottoms with something like a milk crate to get air under them and closer to the light. (just use bigger then what you are in now.^) You can add some distance between the tops and the light. Another 6 inches. Will keep them from burning. Actually that table top would be fine and allow you to fit them all on in square grow bags with more soil. You can use bamboo or something to keep them from falling off the table. Like a fence all the way around in case you bump the table.

If organic never mind this section.
If you don't own a TDS meter or PPm meter they help you to see the nutrient levels in your water mix. In the mean time hit them with lots of nutes over the next few weeks of bud. I shot for 900 to 1400 tds in flower. Also use cal mag. Last 4 weeks molasses is good to add to the mix for taste and smell. Always add the molasses to a little water and mix with a spoon before adding to the nut mix.
Will pop back in to see how they are doing.
Hope that helps.
