    My plants seem to be growing tall. Im in the 3rd week of flowering and I've raised the height of the lights already. Im a newbie on growing so any help is appreciated. Should i just let them do there thing? I heard not to prune them at this stage cuz is risky for a beginner. LST is another thing i heard to do. Which im leaning towards. The grow box is 20" x 24" x 48" growing 3 plants in a Tupperware container. Using general hydroponics grow, flora, and micro along with calMag smd moab bud enhance. I have 2 smal LED lights (1 square, 1 round) budget lights. Any other info plz ask.

    I believe that they are stretching because of lack of light.

    this is what I do in my small growing space... build a scrog net from whatever you like and use it to control the canopy of your grow...just tuck things down during the stretch that follows light switching..at some point though you just gotta let’m bloom...our grow areas are just about the same size...I’ve got 4ft of height or maybe 55 inches...so ya gotta control’m...I keep my lights about a foot above most of the canopy...

    Welcome! I've been in your spot! I hope that you enjoy your journey with cultivating your favorites! How many nodes do each plants show. Its recommended to top right around 5 nodes...
    Now your growing in a box with LED lighting, its still going to get hot, I know mine did! Do you have venting and circulation in your box? You can create a great little environment in that small space!;)

    He's already 3 weeks into flower so topping is not a good idea at this point. A need for more light is probably why they're stretching.

    Yes, i have 2 computer fans. 1 for intaking fresh air to the plants, the other for exhaust. And i have it vented thru a duct into the attic. As far as the nodes...i see them coming out alot if im sure that's what they are. Maybe like 3-5 per large stem per plant. 5 on the large one, 3 or so on the other 2.

    But I've got 2 full spectrum led lights. 1 round and 1 square. Maybe they're not enough wattage? Thinking of doing LST.

    Hey Frank! Welcome to MP! There is a ton of information available here. There are also some very helpful people here to help when something doesn't make sense or you need a work around. There's lots of product knowledge here too.
    What wattage are those lights? How high are you hanging them above your canopy? I try to keep mine under 12". LED lights are different than the HID lighting and can be closer to the plants. On a young plant you may see light stress but I'd be willing to bet most mature plants can handle living within inches of the light source.
    Are you keeping track of the temperature in there? High heat can cause stretch as well.
    Also, I've had plants in the past stretch into the 3rd week. But everyone is right, you're gonna need more lighting once you get comfortable growing. You may want to upgrade the ventilation system. Maybe add some more out fans or one larger fan capable of exchanging the air at a faster rate. I'm assuming you're using case fans and I just don't think the cfm adds up. Those girls need a fresh air exchange, not just heat removal.
    Congratulations on getting your grow going!

    They should stop stretching after this week. Dont prune them.
