First Grow: Mainline Girl Scout Cookies with Platinum LED P4-XML2

Howdy! As stated, this is my first grow. I'll briefly go over all of the specifics of my grow, and then get you all up to date with where I'm currently at. Pictures will be added very soon.

Genetics: Feminized Girl Scout Cookies (AMS seeds)
Medium: Soil (Fox Farms Happy Frog)
Grow Area: 3.5 ft x 2.5 ft x 6.5 ft grow tent
Light: 1st) Galaxy Hydro 300W LED 2nd) Platinum LED P4-XML2
Base Nutrients: Fox Farms Trio (Grow Big, Big Bloom, Tiger Bloom)
Supplemental Nutrients: Advanced Nutrients (Voodoo Juice, Piranha, Tarantula, Bud Candy)

Seeds arrived within 9 business days of ordering, and were immediately germinated on January 20 (T=0 days). Seeds were placed in glass of water overnight until they sank, then placed in Red solo cup with 1/2 perlite, 1/2 Happy Frog with drainage holes in bottom. An immediate problem was stretching, and then low humidity. A homemade humidity chamber was made of cardboard and cling wrap to solve the low humidity. To solve stretching the Galaxy Hydro light was used to ensure adequate food supply for the plants.

T+14 Days: All 3 plants were transplanted from solo cups to 1 gallon smart pots. Mixture: Happy frog, perlite, and Xtreme Gardening Mykos (Mycorrhizal Incoulent).
NOTE: With excellent drainage I was watering them too much. Minimal problem with over watering until later.

T+20 Days: Two plants (Jaws, and Jack) were transplanted from 1 gallon to 3 gallon smart pots.
NOTE: It was way too soon! However, knowledge I had at the time indicated I should transplant too soon instead of too late.

T+24 Days: Jaws had 5 sets of leaves at this point, and Jack had 6 sets of leaves. It was decided to begin a variation of the NugBuckets Mainling method, by using Nebulas Manifold method (Please conduct your own research to determine difference between the two!). Both Jaws and Jack were topped just above the third node, about 1/2 to 3/4 inches above where 3rd node growth was occurring. All leaves below this were cleaned off. Junior was transplanted into a 3 gallon smart pot from 1 gallon.
NOTE: Jaws was stunted for a few days, may have been a bit too soon.

T+27 Days (Feb 16): New light arrived! LED Platinum P4-XML2. Initial impression, very sturdy, large, and well....pretty bad ass. Minor problem; there was a rattling coming from the bearings of one of the exhaust fans. In the following weeks I was able to get a hold of the owner, and he sent me a new fan which I changed out and then the light ran fine from that point forward. Low stress training initiated on Jaws and Junior.
NOTE: There are three switches for lighting: Veg, Bloom, and Boost. I started with Veg.

T+28 Days: Junior had finally grown 6 sets of leaves, was topped to 3rd node and growth cleared below (Same as Jack and Jaws T+24).

T+35 Days (Feb 24): While trying to L.S.T. Junior my inexperience got the better of me. I was trying to create the two distinct sides of the plant. As I was pulling taut with some plant wire, the mainline just snapped from the base, so I only have one side of the mainline. LIGHT: Power increased from VEG only to VEG and BLOOM.
NOTE: Be gentle with LST! "Listen" to your plants.

T+36: Jack had 4 sets of leaves on each side, so next step was to top each side at the 3rd node and clear off all growth on 2nd node (Nebula Manifold Method). This left me with 8 baby colas.

T+39 Days (Feb 28 ): LED to full power. Distance to top of plants approximately 24 inches.

T+41 Days (March 1): Jaws was topped just like Jack, according the Nebulas Manifold method. Since Junior was growing like a champ, it was topped to the 3rd node and the 2nd node was NOT cleaned. This was because I had broken the other side during L.S.T. So, Junior has 6 colas (all on one side).

T+42 Days: Jaws transplanted from 3 gallon container (Smart Pot) to 7 gallon container (Smart Pot).

T+43 Days: Jack transplanted from 3 gallon container (Smart Pot) to 5 gallon container (Smart Pot).

T+52 Days (March 12 - Today): Overall things are going really well! The girls look great, and very healthy. After the latest round of L.S.T. there is nearly a 'flat' top between all 3 plants. Also, I will get some pictures up very soon.

Reasoning/Logic for long veg time and why I used Nebulas manifold method (variation on NugBuckets Mainline method). With limited knowledge available to predict yields I wanted to provide an excellent opportunity to do a high strain quality grow, and get a decent yield. Unfortunately Girl Scout Cookies is NOT recommended if you are seeking high yield, which further adds to my problem. To (hopefully) maximize yield I have decided to #1) Mainline, #2) long vegetative growth and #3) use a powerful LED grow light.

Flowering: I am currently on 18/6, and plan to switch to a 12/12 lighting schedule in 15 days (It will be at T+68 Days from germination).

The fan I have is a Soler and Palau TD-100XS. It has two settings: 100 cfm on "low", and 203 cfm when wired for "high." It is very quiet! I have a grow tent set up in a room that I do not use, and the fan is on the far side of the room from the door. You cannot noticeable hear it through the door as you walk by the room. Unless someone has really sensitive hearing, and is being ultra nosy there are no worries. Basically you can't hear it as you stand outside the room, unless you put your ears up to the door and know what you're listening for. Two final notes: I initially ordered on amazon, and they sent me the wrong one (two weeks wasted) and ultimately bought from build.com (fast shipping!). Second note: I am uncertain if there is enough air flow, however with (6.5x3.5x4= 91 cubic feet grow tent), so a little over 2 full air exchanges per minute.

Fan is very quiet. The first time I wired it up and plugged it in, I was pretty damn excited about how badass the fan was. It was exactly what I was looking for, very quiet and was putting out excellent air flow.

Thanks ViceCity! So far it has been working out, and am I growing optimistic about yield (pun intended)!

Here's an update on the girls. They've turned into some little monsters, and are just growing very quickly and taking up a lot of space!

Days from germination: 71 days (Jan 20 - March 31)
Veg: 9.5 weeks (Jan 20-March 27)
Flowering: 1 week (March 27-April 3)

I did some defoliation during vegetative phase about a month ago, and they all rapidly recovered from it. I decided to go for it again a few days ago, just to try and thin it out a bit. Yes, I know it is a controversial technique, and new growers are not advised to do it. However, I just couldn't help myself.

Anyway, here are a few pictures of the before and after of the defoliation.

Very satisfied. Here is a pic of the girls today, after raising the light to 5 ft. The tall cola on the right side is over 3 ft, however most others are looking around 30". I didn't think that the flowering stretch would be much for an Indica dominant strain. This is one full week into 12/12 lighting.

Yeah, that indica stretch got me too. I ended up having to supercrop the main stalk 5 weeks into flower and she grew a nice knuckle and fattened up real nice

Thanks for the advice ViceCity...I may have to go that route.

Grow Recap:
Days from germination: 81 days (Jan 20 - April 10)
Veg: 9.5 weeks (Jan 20-March 27)
Flowering: 2 weeks (March 27-April 10)

I used Nebulas Manifold method to create 8 colas on 2 plants, and 6 colas on 1 plant. The Nebula Manifold method is a varation on NugBuckets original Mainlining method.

I had to raise the lights as far as I could get them. The lights are at a height from the ground of approximately 5.5 ft (1.68m).

I did not expect a large stretch for an Indica dominant plant. I only expected about a 10% increase in height through my internet research (I do not recall the source) and it was clearly inaccurate. I believe my plants at least had a 50% increase in height which has caused me some problems with height. You can see the issue in the pictures!

Cool grow man, I'm curious to see how GSC turns out with your LED rig. Nice training like a pro!.

Just dont expect great yield from GSC, I think its a totally sexy plant during flower, especially when the leaves turn black.
