In a post by Subcool on about page 2 of this thread about mid way down the following is said:



I've really learned a lot from this thread and have found it extremely useful. Thank you so much for your contributions.

My question:
I would like to clean up my plants lower levels at this point. However, I'm 4.5 weeks into a 9 week flowering cycle. I'm concerned about causing issues for the plant or stunting the growth of my main colas up top. This will not be a problem in the future but for now I'm curious if it would help or hurt at this stage in growth.
I clean my plants up all the way through budding with no shock.

Hey Sub,
What reflector setup would you chose to go as close as safely possible to maximize my lumen efficiency at the furthest point of my grow space. (5'x6'x8'...LxWxH) I will definitely use a 1K HPS but not sure about reflector type.

1) What is the closest a bigass air-cooled hood w/1k HPS be placed? I'm thinking this is the best way to go??? hoping < 2.5 ft

thats about right I keep my hoods about 24-30" above
2) What is the closest an umbrella style reflector can be placed? Next best???

I do not use parabolic hoods but there known to have a center hot spot so I would say 4 feet
3) What is THEE best bulb?????????? Nextgen digital ballast to be used.
Hotilux Eye 1000 hps

Organic all the way,

its the pathogen tho, even using cannazym or any make enzym still doesnt get rid of them. but will break down the old root. and whould have to look after the soil well on the previus grow for it to be in good condition to re use. and the pathogen thrive quik. any over watering or bad feeding, and ya kissing the recycling good bye. but does seem a waste just to throw a reusable substrate away time and time again. growing skills i spose. i read a thing in an old high times mag where the chap was reusing hes soil up to 5 times (5 crops worth) on an flood and drain, said until the soil loses its air holding capability. and using enzyms to get rid of root each time
I've read that earth worms and black soldier fly larvae (probably many other decomposer) can destroy pathogens in their gut.

I don't have a reference, but I saw a study that showed earth worms alone breaking down pathogens.

Black Soldier Fly larvae break down meat and manure really well.

To get a good start on this style it’s important to top the plants early. As soon as my clones have rooted well and have started to grow I chop out the meristem causing the plant to divide into 2 growing shots. If this is performed low enough the plant will actually develop 3 heads just leave 3 nodes
Does this mean the plant will have three colas when it is done?

I've been using 5 gallon smart-pots and was thinking it may be a better use of my soil to try putting 3 plants in a fifteen gallon smart-pot. Sub, have you ever used larger pots for more plants? I'm looking at some large pots that are much wider that high, and am thinking about making them small grow beds. Any feedback would be appreciated.

Top Plants early!

Transplant your plants early!
I topped some JTRs and the remaining leaves dried out. I used new promix and no fertz, and good clean water. Some of them are coming back but very slow... is this typical of this strain? I thought I killed them.

Hey Sub....I know this is an old thread, but I just started growing a few Sativas, and they are fox tailing like crazy, and I know its from the light intensity, thanks to you. I figured it was cause of stress of some sort. Well, I just got a bunch of SpaceJill seeds, Chernoybl seeds, and JTR seeds. Do I need to worry about any of these fox tailing? I'm in a Secret Jardin grow tent, with 600W's, and heat in not a problem....just intense light. I'll keep everything 12 inches or so below the light, should I have anything to worry about? Thanks for your help, your strains, your book, everything you do!!!!!

Mr Cool, Have you ever tried hanging your lights vertical?

I am running 3 kabooms and just started flowering them with 2-1K HPS hung bare and vertical about a week ago. This my first grow so I am not sure what to expect but they all are growing at a seemingly fast rate. If I can find my camera I will post some pics. Also, I vegged them for 2 months in 1 gallon pots/soil under 160watts CFL... They never did get very big.


Thank you for all that you do!

Subcool nice thread. Wish i found it before i started my current grow. I got 6 NL under a 600 hps veged for 6 weeks and currently at 35 days flowering. I topped at the 5th node and the 2 top shoots were tied down as far as they could go. All the other shoots were tied outwards.

This is my 2nd proper grow and first time topping and tying and i was expecting 2.5 oz a plant. Do you think i will get more then? The canopy looks really level and conditions are good. Light is about 8 - 10 inches from top.

You can also just use 2 bales of Sunshine mix #4 but this is my last choice and plants growing in this may not complete properly with this &#8220;Just add water&#8221; method of soil growing.
Hey sub - If you use 2 bales in ur recipe then that would be 1/2 strength compared to if you use 8 bags of soil. Roots bags are 1.5 cuft which is 7.5 gallons of soil, in a bale of sunshine mix is a 3.8 cuft COMPRESSED bag that expands out to almost 7.2 cuft of soil. so if u used 2 then you would have almost 16 bags of roots soil so one would need to double up all the ingredients to make the same strength, which would lead to having to mix nutes up towards the end.

hey Sub,Great articles.I was wondering how using the 7 gallon nursery pots work for a outdoor crop?I live on the cali central coast (25 miles inland) & it can get pretty hot in the summer.I plan on using your supersoil recipe next year.I'm using 2/3 ffof & 1/3 roots organic in the ground this year.My Flav plants are really takin off, about 3' tall and almost as wide.I'll post pics as soon as I can get an adapter.Thanks again for the tips.

I wouldnt use anything smaller than a 20 broseph, ive seen people using 45 up to 100 gal pots... check the outdoor section on this site
 
You say to tie them down when you put in flower, why not during veg? I was planning on supercropping then tie em up after about 30 days, mine vegg for 60.

Sub,
I was just curious as to why you choose topping over other canopy management methods such as LSTing? I would think that LSTing would produce a much bigger yield in the fact that you can end up with dozens of tops vs 2-4 with topping? Have you done any experimentation with LSTing or other canopy management methods? If so what was your end results/Pros and Cons of each method? I'd like to go with the method that typically produces the largest yield.
