    Going from 24/0 veg indoors to outside?

    Hello all. I'm based in New York state. Last year I successfully grew a 7 foot tall indica plant by starting from seed mid march, vegging on 18/6 lights indoor until around may (after frost over) when I transplanted it outside into the ground. It flowered around late August if I recall and I...

    How to prepare for power outage? Indoor grow

    The area I live in is about to get hit hard with snow and ice. I’m really worried about a power outage, maybe even one that could last 2-3 days. What should I do to prepare? Is there anything I need to know? I’m growing RDWC hydro, my plants just flipped to flower about 8 days ago. Should I be...

    Can you speed up auto's finishing? On day 85 for seeds that are 80 day

    I have 3 "80 day" auto flowers going, it's day 85 and 2 are done, but 1 looks like it is lagging by 2 or so weeks. The problem is I am going out of town in 3 weeks and need time to trim/dry/put into jars before I leave so it's easy for a friend just to burp the jars. Do you guys know of any...

    Best Light Cycle

    I have a 600w hps yield lab and I do not want to stress my plants. I’ve read somewhere that plants need darkness even in veg. And if I can run 24hrs without stressing my plants is it to late to start now. Right now I’m running between 18-20 hours on 4-6 off.

    LED Help: Should I be using both veg and bloom switch?

    I have a Full Spectrum 1200w LED light in a 4x4 tent, growing autoflowers. The light has a veg switch and bloom switch. My girls are little over 1 week old. The information on the LED instructions seems to contradict the things I'm reading online. So, I'm asking the experts (ya'll). The...

    Light Cycle

    Hi there, just started a Sativa dominant strain (Lambsbread Collie) indoors; should I increase the light time? Read somewhere that they like more light as the normally grow near the equator. Started on a 18/6 cycle... Any advice appreciated! RW :peace:

    seedlings stopped growing after switching to 12/12 light

    Hi, newbie here, a few weeks ago I switched my light schedule to 12/12 to make my mature plant bloom. There were a few seedlings in the same tent as well, and because I only got very minimum grow space, I just left these seedlings there. And now I have noticed that some of them have stopped...

    Hydroponics Nutrients and Auto flowering Cannabis

    This will be my first post. I have been seeing a lot of disinformation about hydro nutes and Auto flowering growing. To be clear this is not a reference on soil mixing, I am talking about Ebb and Flow and DWC. This is not for soil, it just isnt. Okay. I have been growing autos for a while and I...

    Preflowers in Veg

    I have a clone that is showing pistols on a few nodes. It is currently under 400w hps and is about a month old. Its currently on a photo period of 16 hours on 8 off. My question is: Is it normal for my plant to show preflowers with this many hours of light? Or is this just a sign that she is...

    Hey guys, So I still use one of those old intermatic timers, that have two markers and you adjust them by screwing a pin onto a metal pinwheel that spins past and flips switches. Somehow the on pin became slightly loose, but would only slide slightly each night before catching again and...

    Light cycles

    I have a multithreaded question about cannabis' light/dark cycles. The tried and true method is 12/12. In the past few years it's been more 11/13 around. We also have the idea that you could start 12/12 and slowly change to 9/15 over the course of growth. Then also we have 730nm sleep...
