DWC Grow #4– Auto flower

Discussion in 'Hydroponic Grow Journals' started by pizzaeater, Aug 30, 2019.

  1. Documenting my fourth grow. I have a link to my first two grows in my signature. I will be posting weekly photo updates. Comments welcome.

    Info on the equipment below.

    Vision seed Northern Lights auto
    3x3 eBay tent
    300w eBay led ufo
    GH Maxibloom. Using the Lucas formula that is 7 grams per gallon. CalMag & Hydroguard

    Started on 8/25 in a Rapidrooter under a 23w 5000 CFL on 24/0. I'll switch over to my ebay 300W ufo led after the root drops below the netpot.

    There are no additions to the water, I set the ph to 5.8.

    Here is the first pic from 8/28.

  4. Day 7 Northern Lights Auto

    The tap root poked through the net pot.

    The ph has been stable at 5.9. I added CalMag an Hydroguard several days ago according to the recommended strength for 3gallons.

    The ufo light is 12 inches away running 20/4 schedule.

    It won’t get interesting for a few weeks but thanks for stopping by. Will be posting weekly updates.

    Day 14 Northern Lights auto

    The grow is on autopilot as ph has been stable 5.9.

    I’ll swap out the bucket for a twenty gallon bin in a two weeks for the first rez change.

    Some pics for interest. I converted to black and white as the purple lighting is hard to see.

  6. This gets me excited to start my autos as soon as I receive my seeds! Really looks like she started off good man!
     
  7. WOW! ONLY 2 WEEKS IN AND SHE ALMOST HAS WHAT...5 NODES?
     
  8. Day 20 Northern Lights Auto

    Looks like I'm having Cal/mag issues on the old growth. I topped off with 1/2 gallon of ph and Cal/mag water with an additional 1/2 tbs of Cal/mag. PH set at 5.9 and will check again today.

    I started LST in a few spots over the weekend. This weekend will be a full rez change.

  9. Day 21 Northern Lights Auto

    Nice growth over the last week. The plant is almost extending beyond the diameter of the netpot with the root ball more than doubling from last week.

    I realized that the timer was not shutting off so the light was on 24/0 for the first 3 weeks. It is now set at 20/4.

    I’ll be monitoring the spotting over the next few days to make sure it doesn’t spread beyond the old growth.

    I included a picture of how I LST using rubber bands and twist-ties secured to the netpot ring.

  10. Day 25 Northern Lights auto

    I changed out the bucket for a 20 gallon tote Sunday morning. The tote holds about 10 gallons. With a larger surface area, I can go a few days without topping off if necessary. The larger volume also helps keeping ph stable.

    The outer rim of the tote lid also has my DIY LST ring. Here are some pics of the girl in the tote, one pic is after a gentle LST session opening up the interior of the plant.

    I also included a pic of my gear. Maxibloom, ppm meter, ph adjust fluid, ph meter, hydroguard, ph calibration solution, cal/mag, 1tsp dropper, jewelers loop and snips.

  11. Day 28 Northern Lights Auto

    I added about 1 teaspoon of Maxibloom to the 10 gallon rez. Ppm went from 417 with just cal/mg to 475 with the nutes. The roots are stained from the Maxibloom and are not suffering rot.

    Topped off with a quart just about everyday for the past 2 days. As soon as I see a drop in ppm I’ll know to begin increasing the Maxibloom.

  12. Someone had a question on the auto fill valve in the last picture of my previous post asking if it works well.

    I did use it on my last grow when I would be away for a week and it worked well. But the fill bucket needs to be higher than the level of the Rez.
     
  13. Day 35 Northern Lights auto

    The grow is progressing with little issue. Ph is stable 5.8-6.0 ppm @517-535. She is drinking a quart a day. Here are som pics from Wednesday.

    The LST I’ve been doing with the ties and rubber bands have resulted in two broken stems. I have been able to save them with splints and tape but decided that a scrog would be a better option. I built this for my first grow but never used it. Made from. PVC, screws and string. This is from Friday day 37.

  14. Looks nice. Has it started to flower at all?

    I've got 2 5 gallon dwc auto widows growing and got to about 42 days and no sign of flower. I was running out of tent room fast so I tried a 12/12 light schedule, I'm now on day 4 of that and I have stretch and flowering starting on both.
