How can I slow plant growth?

[greenmountain]

Hey. Im trying to discover a way to slow or stop plant growth in veg.
These girls are in coco and are to tall. Ive topped them three times and don’t want to top them again as they will be flowered in about a week. Any tips to make this happen would be appreciated. Im not sure if this is possible.

I’d recommend bending the new growth tips down at least once a day as low stress training, and putting a vinyl coated wire mesh screen above them in flowering to limit height from stretch. I just had a similar situation with some ethiopian x afghani plants in veg in my organic indoor grow.

Pictures are helpful.

Ever bent somebody’s arm?

Cold temperatures, low light, low nutrients, and frequent toppings are how I keep my bonsai mothers small.

Is the issue truly too much growth, or just too much height? If it’s the latter, @Mr.Sparkle does some spectacular feats of height maintenance.

If it’s too much growth, reiko is on the money. Low root temperature is guaranteed stasis, along with low wattage light, or regular wattage for just a few hours here and there.

Less lamp-hours/intensity, cooler temps.

I remember a greenhouse owner telling me he used a B vitamin? spray ? to keep plants uniform and when people took the plants home this stuff would be watered or rinsed out and the plant would resume normal growth , I think it was B1 but please don’t quote me.

Allow me in the same room as them. Always works for me

How low do you go on temps, light, and nutrients – are you able to share some kind of a starting setpoint on those parameters? Are your mothers in dirt?
Last time i grew, years ago, i just took clones off the plants going into flower, and rooted/veged/topped them while the originals flowered, then rotated and repeated. This time around i’d like to tighten up and keep a couple strains as mothers.

Let’s get it right this time(ish) So I made a ton of mistakes throughout this grow, and came to accept that I’m a total noob, so in humility I come here to share and record my experiences so we can all learn from my mistakes, and in doing so I hope to improve my skills and knowledge of our fine craft. We started with 7xNorthern Lights Fem and 1xWhite Widow Fem from Canuk Seeds. Seeds were dropped February 24th Yes that’s right, the plants vegged for 12 weeks under recycled diy T8 fixtures in …

Use small pot, white/blue light, temps below 75, 8/4, 8/4 (on/off) light schedule, lower nutes/water and if they grow too much, chop 'em.

Here’s a good place to start. If you type bonsai in the search more useful threads will come up.
