    Newbie here. 2nd attempt with hydro/closet grow. First go 'round root rot tanked it. Too much light and too much water way too fast. Seeds are as the title states. Light cycle is 20/4. Technaflora veg recipe at 1/6th strength. Lights are 2, T5. Basic questions I have are:

    1) When to turn on the LED panel?
    And
    2) When to introduce CO2?

    Any ideas/ feedback are appreciated!

    Post to be regularly updated weekly so keep checking back! Comments/questions are welcomed!

    Nice setup! Looks expensive. I'll be watching as I have a white widow auto to pop in the spring

    Expensive isn’t always good.. look how small that space is and how close all the net pots are together... not good, how will you do a res change? Its a beautiful setup but personally i think it was all a waste of money.. especially because it seems like you have a lot more space in that room..

    Good luck.

    Although yes, (and no, I'm not very proud of the spending) it was expensive. But, that's not the point as to why I purchased it.

    I wanted a contained unit that doesnt occupy an entire room and I wanted to have as much control over the direct atmosphere of the grow and I figure this is the best route to go.

    Now, regarding space. Space is of concern, but only depending on the method. Yes, I'm aware that there's plenty of ways to maximize yields and such, but I want to just focus on a successful start-to-finish grow with emphasis on 1 single, spectacular cola per plant before I delve into the methodology of other techniques.

    To expand a little bit, the cabinet can easily be cleaned out and sterilized and allows for a little bit of security from prying eyes.

    Nirvana, the reservoir has a tube that I can turn a valve on and the pump will push all water out.

    To reiterate, I AM looking for tips regarding the questions in the op.

    Stay tuned framia

    I can't help you out with those as I am new too but I think you can learn a lot from @Soil2Coco

    Looks like a nice setup. Space is a concern but it looks clean and organized. DWC is a pain in the ass Compared to DTW IMO, but get through a grow or two and tweak it to suit your needs. I’ll help if I can

    @Soil2Coco I've posed a few questions in my initial posting. Any recomendations?

    So, I just had another question...or 2

    Being autos, what kind of thirst will they have? How rapid can/will I need to increase nutrient strength?

    In DWC you can monitor the plants ppm levels and how they respond after feeding. That will show you that plant's preferred nutrient strength.

    I'm not experienced with growing autos but they're not that different then normal plants as far as how you keep them happy and growing.

    There is so many plants in that. You'll have to keep them quite small in order for them not to crowd each other. I average flowering about 4 plants in my 4x4 area. Looks like you have 16 in a space half the size.

    As the water level in the res goes down if the ppm level goes up then the feed is stronger then the plant wants it. You can imagine the ppm is going up because the plant is leaving extra nutrients behind as it consumes water. If the ppm level goes down as the water level in the res goes down then the plant wants a stronger solution. In that situation the plant is sucking down all the nutrients and leaving water behind. I've had plants feed so hard they drained the res to 0ppm in about 5 days.

    Small starter seedings don't need much light to get started but the more light the faster they will grow to a point. You have to learn to watch the plants and tell when they have too much light. I would run the led in veg mode raised all the way up and work my way down as the plants get larger to the recommended light distance.

    Just watch for upcurled serrations on the edges of the leaves. That is the first sign of heat/light stress. Too much light and too much heat pretty much give you the same symptoms.

    CO2 is mostly used to supercharge the veg process and increase temp tolerance. You can start running it whenever you want but in such a small space you'll have to be careful crowding plants or outgrowing your available headroom.

    Excellent excellent reply. Everything I've had an issue with comprehending, you've clarified.

    I do have to say, I'm not sure this light has a "veg" mode. Also, could you give an idea of how much co2 these can handle?

    1200-1500ppm is recommended. 85 degrees minimum temp.

    You talking about the CO2, I’ve also been curious about that. Thanks for the link Tbone!

    Cheers!

    Leave it off at night. It's all in the link. Good informative article from Growweedeasy. Pretty much the internet bible for weed growing.

    So, updates.

    12 plants going, but I'm pretty sure 1 is handicapped. I'm not sure if I should pull it or leave it.

    co2 is running 30 minutes after lights on and stops 30 minutes before lights off.

    Humidity is tough to wrangle here. Cool mist humidifier added, but the best after a long 20/hrs is roughly 57-60% and I've seen lows of 50%

    5 of 12 plants have 1" plus of root out the bottom. Roots are white and seem healthy.

    Lights are 20/4. LED panel is K3 L600 from Kind. LED panel turned on yesterday. 3' acclimation period for 3-5 days. I will lower it by 12-18" after a few more days. Then, 10" if I see they can handle it.

    I have yet to turn on top feed and I'm thinking I shouldn't need to (any thoughts?).

    Take a look and let me know what you think. signal-2018-10-11-182850.jpg signal-2018-10-11-182845.jpg View attachment 2517275 signal-2018-10-11-182841.jpg signal-2018-10-11-182836.jpg

    New question I havent found an answer to yet.

    With co2 introduced, I understand plants can handle high humidity and temps. But, what about when lights and co2 are shut down? Should humidity and temps still be held high as if they are on?
