Stretching

[cool09]

I'm well into flowering on 2 plants (Haze and White Widow). Haze has stretched the most - it is 39" high, branches in the middle (stem to tip of buds) are 15", all branches have buds (minimal size). White widow is maybe 35" and not nearly as stretched but not compact, either. This is my 5th grow and I did not know that stretching was bad and none of my crops (except one: 2 Skunks) produced any stone effect. (All triches on my grows stayed clear well into flowering - over 12-13 weeks. And all were indica/sativa hybrids).

I did not have lights close enough during veg and most of flowering. I brought HPS much, much closer (~14"-16") 5 wks ago when I got info on how to cool the HPS. I'm using 2x250W HPS on 9-10 sq ft.

Buds are now growing slowly (and most about size of golf ball). Wanted to ask if I should abandon this grow? If these plants are not going to fully mature and/or produce any high due to stretching I'd like to trash the plants.

Stretching in it's self does not hurt anything; if you have extra height available.

white widow can produce long, heavy single colas :thumbsup:

I thought stretching makes it harder for the buds to get nutrients and grow, stresses out the plant and growth (during flowering) becomes slow?

I don't think that makes any sense. sorry, Bub.

What are you feeding them would be first question?
Where were genetics received would be second?
Weak genetics aren't going to produce as much as genetics from a reputable source. Feeding also very key

OK, biochemist.

"Why is stretch a problem?
Stretch is a problem primarily in indoor grows because it greatly reduces yield. The problem stems from the limitations of artificial light and the plant’s adaptations to low light. Stretch also produces tall plants with weak and spindly stems. The weight of the buds later in flower will require staking to avoid damage and falling over. Stretch may be a sudden problem for growers with limited ceiling height.
Light intensity vs internodal distance - Light intensity diminishes exponentially with distance under artificial light (the inverse squared law). Sunlight is not affected by distance and can penetrate deep into a canopy.
Marijuana requires high light levels to thrive and produce high yields. A plant is at its optimum flowering height when all it’s bud sites are bathed in intense light (ideally the entire plant is equally lit, producing dense bud from top to bottom).
Stretched plants are tall and their lower bud sites receive exponentially lower lumens than top colas. Budsites that are not receiving intense light will not produce well, and often the light and extra plant height is wasted. Tall plants require more energy to pump water to its leaves and transport photosynthate from its leaves. This extra energy could have gone into flowering. Stretched plants can yield 30-50% less."

I feed Foxfarm per Foxfarm schedule and from a reputable seed source.

i think the "stretching" they are talking about is when the plant gets too little light and has to reach to get to it. it makes the distance between nodes very long like 8-10+ inches as opposed to maybe a couple inches here and there.

Obviously you have something else going on besides some stretching if you are not getting a buzz. Lower buds are hard to get right unless you grow short plants or have some side lighting set up. Stretching will not make the buds bunk. Even my lower no count buds will catch me a buzz. Members like Dutch and Shovel know what they are talking about and have been doing this for a long time. Lets see some pics of what you are talking about.

Have heard many times, a little stress make you tough, or maybe stronger.

Foxy base nutes? Additives? Also, what about your rhizosphere? Roots equals fruits. But just based on the lighting, usually 60 watts per square meter is recommended for good yields roughly equals about 600 per meter or 9 square ft and a 1000 watt for 4 feet squared. If not stretching can occur especially with a heavy sun loving sativa, which reduces yields. Supercropping many times can help with stretch increase yield and help with ceiling too close to light issues.
