WHen should i induce flower.

[Tranceus]

If im growing hydroponic sog in a 4x9x6 1/2 ft room using 400w air cooled hoods at what height should i induce flower? remember that my 18 gallon systems are like 15 inches tall.

 

[kermit2692]

all preference....imo 2 ft is good...mayyyybe 3...from what ive seen any higher and your just wasting space because with a 400 your light penetration wont be huge...any lower than 18 inches and your plant wont be as thick you will yield a bit less...

I would agree, I run a 400w in a 3x3 tent, with a cool tube it's a bit on the low end of the lighting needed. For that size room two 600w would be near perfect.

Sounds like your space is too big for a 400.

When in doubt, flower now. Keep notes and next time you'll know what to expect.

I like to go 3-3.5 foot and remove the bottom foot of vegetation for air circulation and easy maintenance. Expect ~50% stretch in flower so 2' veg will give you 3' plants at the end.

i see ppl do that gotta ask whats the point of waiting for an extra foot to grow if u just chop the vegetation on a foot you already had....just curious manif theirs some secret i wanna no it lol

depends how much control over your plants u want,smaller is better to control 5 ft plants are a fuking pain to deal with and trim at the end, and bigger plants dont mean bigger buds,rule of tumb is your plants will double/triple in size wen flowering,hell i flowerd mine at 6 inches nw ther 2-3 foot tall lmao

 

[colonuggs]

it depends on your strains that you are growing....and how much of a stretch they put off during onset

I have a purple og that only shoots up 6 inches during the 2 week onset period

I have a sour deisel that will tripple in size during the 2 week onset...10 inches becomes 30

You have to grow your strain out one time and figure out how much of a stretch it gives off during onset

dont forget to clone your plant

I flowered mine (Northern Lights) when they were about a foot tall. They doubled in size and stretched a lot in the last 20 days. Starting to see nice buds forming.

i used the word hoods. meaning more than one for the space im growing in just to clarify the lighting issue, has anyone had any experience with the strain. "kolossus" from sannie?

I like to top mine so the plant basically becomes inverted. Think about this. every time you double the distance from the light the power of the light is quarter strength. So you want the largest diameter of plant close to the light as possible for maxiumum efficiency. This is why screen of green is so popular. Without topping the largest diameter of the plant is on the bottom getting much less light. This has some drawbacks in that the vegetation below it is blocked more. You end up getting tiny buds below the penetration line, as I call it, and wasting nutrients that could of been sent to buds close to the light. So anything below the penetraton line, usualy 2-2.5' from the top down, I strip. Like I said the advantages are: Less work at harvest time, easier to spray undersides of leaves during mite infestations, and better air flow. Now to your question; Growing the plant taller than the penetration line also gives you a larger root system to feed those buds as well as the other benefits preveiously listed.

have never gotten mites....but i see what ya mean u just cant get a huge circumfrenece until you hit a certain height??? so you believe its better to hit the higher height and larger circumfrence than to have a smaller plant altogether??

the only thing that scares me is the fact that i dont really have much grow space and im needing the max yield. if i do a scrog then my whole room will have to be covered in net and it will be hard to change my dwc resivours and shit like that.

 

[kermit2692]

dont you have plenty of height clearance tho??......i still think 2 ft is good myself but im always looking for high yield and some of these guys nail it!!

I just drilled a hole into the bottom of my bucket, then I put in a drain. That's how I've been working with my bubble bucket sog. Makes checking ppm and ph easy too, just open the valve into a cup. No trying to lift up my 4x2 screen.

I let mine get to about 18 inches and this is how big they get. These are Critical Plus.

They are about 44 inches tall.

depends on strain i switched to 12/12 on some whiteberry at like 18 inches as well and they didnt get much over 2.5ft when they were chopped
