Hello all. Just recently started my second grow 2 days ago. My first grow was a learn/upgrade as you go grow and it turned out decent. I started with 2 fluoro tubes and ended my flowering with a 175w MH and got a little less than an Oz per plant.

This current grow will be done in a closet. The closet setup as follows: ~3ft x ~2.5ft x 8 ft, 400w HPS w/ Hortilux bulb and batwing reflector, 2 6" in line fans at about 150cfm and a vertically standing fan for grow room circulation. My medium is Cocogro that will be mixed with some perlite when put in the final pots. FoxFarm Big Bloom and Grow Big will be used throughout along with the Tiger Bloom and the other 3 nutrients when the time comes. I keep the water's pH right about 6.0 or a little bit less.

Some additions that i will be doing throughout the grow is I will be getting a cool tube that will exhaust the hot air straight into the attic. Hopefully some panda or some mylar( ihave white walls but want something a little bit better.


Now onto the children. I just started germinating the 10 seeds in paper towels saturday. all 6 northern lights seeds cracked and sprouted in less than 24 hours in the coco. Both Lemon Diesel seeds have cracked one is still in paper tower and one is sprouted. I also started a bag seed that i hadfrom some good headies not too long ago that has sprouted. They are under two 32w fluoro tubes and 2 of the i think 26w(whatever the 100w replacement is). One is the 6700k and the other is the warm white color. more cfls will be added weekly until its time to throw them under the HPS.

My goal for this grow is to grow the 6 strongest plants and induce flowering at about 12" tall. I hope to get a yield of at least 6oz. Is this reasonable?

Questions and comments are welcome. I will update frequently with pictures.

the second picture is a hermie that a buddy had that i tested the closet out on. it was super stretched when i got it thats why its sideways. I hate that fucking plant so much.

lol u hate that plant huh, nice grow im doing the same as u, and have 6 plants i wonder if we can get 6oz

yea. the only reason its still going is because the guy wanted me to grow it out for him for the seed under the terms that i get that light. pretty good deal i suppose. i think 6oz should be within reach but i guess we will find out. 6 oz is only ~180g and thats would be less the 1/2g per watt which isnt that good i dont think. i believe the limiting factor in this will be grow space. i wonder if lollipopping the plants and doing a sog with more plants would be more/less efficient thanvegging them for a couple weeks and growing maybe 4-6 plants total. any input

a quick question in case anyone reading this can help me out. When i make my nutrient solution i usually do about 2-3 Teaspoons of GrowBig(6-4-4) during veg. Then when i switch to flower i do a teaspoon of GrowBig and then 2-3 Table spoons of BigBloom(.01-.3-.7). I did the calc for the ppm of the mix i use with flowering and i only got 224.84 ppm for my mix. This confused me because my leaves always look a bit burnt up. Was my calculation wrong? salt build up in the growing medium? or not enough nutrients? this is something i would like to get figured out before i start feeding them.

Update:

I now have 7 strong growing seedlings and another germinated seed that just went into the coco late last night. 8 or my 10 seeds germed successfully( i lost one and one was a dud) and 7 out of 8 of those that germed have sprouted. Below is a picture of the two strongest seedlings at the moment. NL on the left and Lemon Diesel on the right.

I'm growing under 400 as well, but with 12 small plants hopefully. your space is pretty much the same as mine, and I was having serious heat issues without ventilating it out of the room with a 300CFM fan. you should consider using Fox Farm's Ocean Forest, it works well with the nutes you're using. plus it wont dry out as fast as the coco under that 400w. what are you transplanting them into? 2 gallon black grow bags are perfect for your space... good luck on your grow.

yea its gets pretty toasty real quick in the closet so a cool tube is a must. If i were to switch to the soil how often to i need to add nutrients to the water since the soil already has a bunch in it. and i will probably use the grow bags now that you brought that to my attention. it seems like they would be much more suitable for tight spaces.

well with good soil you dont have to add anything for a few weeks anyway... if you only had 6 plants...grow them all up as fast as you can..when there alll big enough to take cuts...take 2 of each and label which plant they came from... then force the clones into flower somwhere else..and you will see which clones are male or female ...from there throw out the males and make room for the females..if you were to put up a screen in that room with 2 to 3 plants and scroged it you could easly get 10 to 12 ozs... good luck..

thanks for the advice i was thinking about how much of an advantage a scrog would be and if it would help the yield that much then i mught have to do that myself
