Welcome to my 1st DWC grow, be sure to drop a like so I can visit your grows.
Wk 3 VD15 Growing, a little slow but it's growing. Its very clear this is my 1st DWC grow.
Having real issues with temp for water even though the air pump is in a colder room at 21c. 21-24c too high. And it's showing in the roots.
18/5/22 Figuring out how VPD works. You could read for hours about this stuff and still not dial it in for years.
But here's the basics. VPD 0.4-0.8 kpa for early seedling. So under or around 23c and around 50-60 RH. atm my VPD is 1.05kpa and for most of my plants the optimal range is .8-1.1 kpa. Temp is 80 F 25-26.5C and RH is 70%. To find the perfect VPD (Vapor Pressure Deficit)check out optimal ranges of VPD for growing stages, also your strain should have the optimal VPD. I don't have an infrared temp to check the LVPD (Leaf Vapor Pressure Deficit) that's a whole other ball game
Checked PH was 6.5, adjusted to 5.8 with PH - crystals. Seems to keep a more stable PH for longer and doesn't mess with the PPM. IDK if it's good or not but the PPM has stayed the same the past week, May be dropped by 10ppm. Just the PH keeps going up. So, my meaning is it's drinking and the PPM is set just at the right level. As I've not filled it up since I put water into it. And as it's drinking the nutrient mix it's taken everything up and just leaving the PH adjuster from the nutrient additives. If the PPM drops I will not that I need to add a little extra nutrient mix.
Decided to add Fire Yields, It was meant to be given the 1st 2 weeks, but I was given a chart that says on week 3-4 so I didn't know, so it got started now. Plant seems to be doing ok. Bit droopy, but has steady growth. Having real issues with temp in my tent. It's 26.5 with lights on and 22 with off. If I wasn't doing photos I'd be doing a 5-1 light time on/off. As the water is a nightmare to keep under or even close to 20. I just can't get there. 4 times a day I'm having to add full bowls of PH'ed water. It's a poxy pain and I can only get it to stay at 22. Only thing, these enzymes aren't meant to go bad until they reach 25 and there's always a degree or 2 you can push them. But I also know there's other bactria that will end up coming. I'm only going to run enzymes until I get a decent root structure and I'm getting there with this 1. The mystical green has made a kind of black stain that easily wipes away from the roots. I'm not going to bother washing them, as this is stuff to keep a stable environment and does a lot more. So it's going to be given threw the whole grow. Having to adjust the PH every 48 hours back down to 5.8 and I adjust it when it reaches 6.3-4. At the moment I'm just adding PH - crystals. It holds a steady PH longer than liquid. 48hrs but I haven't pushed it past that. As she gets bigger and drink a more I'd say the amount of PH adjusters from all the different nutrients that will be added and the more it drinks it'll leave more. EC/PPM hasn't dropped at all so it's still perfecto. But I'm thinking that's going to also drop soon. The roots are deep. Hoping for big changes this week. I won't be changing the water for at least 2 more weeks now. I'll add to it but I only added fire yields and I'm not wasting 40ml of it so it's staying for 2 weeks. I will give the roots a light wash though as I don't want their little side vain roots getting clogged up.
22_5_22 Decided to FlMing, done the 6th node coming up. If I done.
23/5/22 Done defoliation. Some light sulfur or calmag def. Have added calmag and sulfur.
That's it for this week, other than pics of the rest of the week and I'll take root shots also.
Thanks for reading.

@LoveGrowWeed, thanks. These seeds were actually sent by mistake. I ordered the same strain but in auto version. Was meant to return and I'd get what I ordered but took it as a sign. Looking forward to getting into mainlining the coco/soil 1. Just gonna veg this for 4-6wks depending on growth and lollipop her. Height says only 80-100cm so won't have to do much. Will be a nice strain to scrog. Maybe I'll do 1 in my 70x70 with my next 3 seeds. Looking forward to trying GHS breeder they have some sick looking strains. So unique looking plants like TH seeds. I find FB strains unless you have the temp swings or unless it's something purple it's very hard to tell their strains apart. But if you got the temp swing they look somewhat dif but still not by much. But you can't beat them for their solid genes. I've yet to see a hermie on any1s FB grows.
@gottagrowsometime, some of my first grow way back in the day were GHS , I think maybe it's time to give them a go and check and see what they got going on 👈
@northernMike, Hey brother. Yeah, I done it wrong from the start right up until I put them in the tanks in wk 3. Should have put them in from the beginning into the o2 filled water. But they taken off now. Once you dial in it, it's fine. Just have to adjust PH every 2-3 days. I'm sure you'd get away with l9nger than that but once mine goes up to 6.3-4 I bring it back down to 5.5-5.8 and just leave it.
Good luck bro.
@gottagrowsometime, I just put two beans in the soil today after a couple days in papertowel, these will go
outside as soon as it's warm enough, Green Potion Fast Fem from Canuk Seeds and U.K Cheese auto from Oasis Seeds.
I'll probably pop a couple more auto's in June. Just ordered some new seeds, all auto's, and I got some feminized seeds for free,
so I'm good for awhile now😀..
Have a good one!!!
@northernMike,
Good to c u man. Yup, been awhile. Things are good here. Decided to go a little bigger this time. Then gonna finish up for a few months and enjoy the summer with a bit of bud stored up. Don't fancy having to do 3-4 grows every 2+ months.
@Tropicannibis_Todd, cheers buddy, she's been a nightmare, or better yet, I've been her nightmare. But, we've seen to have turned a corner. Thanks for dropping by pal
@Grow_for_Happiness, it really is a super light. As for the temps. The driver gets very with my volts. As it depends where you are the driver and bars can be from 30c with 100-110v 40c with 110-200 or like mine which is 50c if your volts are 200-240, so it really does depend where you live pal. bars are around 40 but the heat doesn't really come down onto the plant if you get me. Its a heat sink, so its hot but its spread out so, but yeah, in my country with our volts the drivers on every light I've had gets into the 45-50c range. The bars are cooler, but its a great light. And unless your grow room temperature exceeds 28c like mine atm you won't have any issues. My tent is 32c atm, my plants are having a hard time of it. But air temperature doesn't necessarily mean that's the temperature of your plant, if you have good ventilation and a good oscillating fan you should be able to keep LVPD at a decent level....if I can grow DWC with water temps at 27c and all my soil grows were fine. But most were harvested before the summer hit. At this time of year a lot of ppl don't grow as its too hot, hence why Mars are giving a 13% discount on all their stuff and for an extra discount use my code for a few quid or so off or if you can find a better code.
It really is a good light. Hope this helped..
