Fat Banana - RQS - SF1000D times two!

Scandic They have now all sprouted. So i guess this is week 1. :-) Day 3: Until now I only watered around where I planted the seeds since their roots wouldnt reach anywhere else for now but on.. Day 4: I gave each plant about 0.7L water to each pot to moisture all the earth. I may think I should have given them more since they are in such big pots. So thats something I will have to keep an eye out for. Day 5: I moved the lamp from 60cm to 55cm because I dont want them to stretch and I want to maximise their potential. Also trying to raise the humidity. It sometimes drop to just below 50% if I dont help increase it. Fat Banana Automatic from Royal Queen Seeds.

Scandic Using plastic bags to raise the humidity to around 75% cause its only 50-60% in the tent if i really try to raise it with spraybottles and such. But for now this works and i think they look good here on Day 7. Which i will consider as beginning of week 2! Day 9 - 28 August: They grown a couple cm more and is more bushier now. I wont post pics before week 3 though. Its looking fine though. Gave 2/4 nutrients today. To see the difference on the 2 which got and the 2 which didnt get or didnt get as much atleast. And I topdressed the grounf of two of the plants with a bit of Bat guano which should help later in flower and with alot of P. (3-15-4) Also manage the temperature better now. Still trying to find out the best lamp distance though? Any suggestions from people who know the SF1000D? Thanks!

Scandic Day 14: (start of week 3) They are growing great and I know that they will grow even more the next week, so I’m excited and hoping everything will go well. I will soon start LST but they still too short and compact for me to do anything. But I will update during the week here in this section. Day 15: LST begins Day 16: Fimmed one (plant 3) which I couldn’t do LST to. Day 19 I had to flush all plants because my runoff was too acidic (5,5ph). Now it should be around 6,2 again. Couldnt see any defficiancies though and all plants look healthy. One even grew too much and its the one I havnt been able to do LST on that much, so I topped it. So I now have one plant topped, one plant F.I.M, and two plants has only been done LST to. I took away one or two leafs total which was blocking bud sites too. I want more top shoots and as even canopy as possible. But im missing some LST clippers which would have helped me alot. Im now just freestyling it with tape etc.

Scandic Day 21 from seed. Start of week 4. One plant is topped. One plant is F.I.M. And two has only been trained with low stress training. I had to flush all 4 plants cause my PH was way off. And since im using synthetic fertilisers, I suspect that was the cause. So i raised the PH to around 6.2 again now in my runoff. Day 23 Fighting the High humidity. Im on 60-65%. I rather be between 50% and 60% at this moment. But as long as I can get it down when flowering starts. I also raised the light hours from 18/6 to 19/5 last week and today on day 23 i raised it to 20 hours of daily light. That should also help me from getting the humidity too high since its when the lights are off, the humidity in tent raises. Beside that, they are beginning to fill out the space and im slowly seeing signs of flower on some of them. But I hope they will be in flower next weeks Update. I hope i can finish them all with the space i have. Thats why im doing LST and defoliation also. Beside it being beneficial for yield and so on. Day 24 A day with around 60% humidity and 25c. I have seen signs of flowering on them all now. So next week will be week 1 of flower (BTW: The PPM is what I read from my runoff water. I only feed with around 6-700ppm atm.) Day 25 Defoliated the plants today (bigger fan leaves in the top and small budsites which I dont want the plant to waste energy on and I lollipoped one plant too where i removed the bottom 1/3. I like to try different things to compare in the end. And I will share my results towards the end. Day 26 Defoliated all plants cause they were touching eachother more than I like. They are growing good but I thought they would be taller now. But im also keeping them low on purpose. They about 25cm i think.

Scandic Day 28 from seed and the first week of flower! I finally got things dialed back in and the plants should thrive this coming week. 2 out of 4 have a little nutrient burn but I just watered them all with normal water with the PH of about 6,6. Run off was 6-700 ppm which im happy with. PH about 6,5 🙏 Next water will be a feed. And then ill water again and then feed. But offcause watching the plants reaction meanwhile. Will update during the week. Comment if you have any tips for me! Still fighting with my humidity. And i Got another SF1000D LED lamp from spider farm on the way. To give the plants some extra light here in the flower time. _____________________________________________________________________________________________________________________________ Day 29 Heavy defoliation on all 4 plants to lower the humidity. I probably did more than I would have if I didnt have such a high humidity. My VPD is alright though for the most of the time. Day time its around 24c and 60% RH Night time its worse and thats why I now have 22 hours light on and only two hours off. Where humidity raises to 69% and down to 21c. Measurements are in canopy height in the opposite corner of my ventilation where I think its worst. Nutrients: I will hold off with the mineral nutrients for the next couple of waterings after I got a slight nutrient burn on some of the plants but I topdressed all 4 plants today anyway with some Bat Guano from Plagron (NPK 3-15-4) because the two plants which I gave it to in the start of the grow (week 2) is also the two strongest plants at this time. I only gave a little this time even though an overdose shouldnt be possible. It will also first set in 2 weeks from now. So a nice boost for flowering. Hopefully it will work great to combine Organic and Synthetic. I heard they call it Synganic. :D Day 31 Had to raise the light period to 23hours. Not ideal. My humidity is too high. I’ve had to buy a dehumidifier for around 40$. And the SF1000D LED lamp has arrived and will be put in the tent tomorrow. Hopefully it will help me on the humidity, now when flowering soon should start for real. Day 32 Watered them all with PH´ed water at around 6,6 which was also what came out. Next time Ill be giving them a small amount of food again. Day 33 Humidity and temp is under control again. And is now in optimal VPD ranges for flowering. Currently 25c and 56% RH.

Scandic They keep growing but as I entered flower, problems begin to arise. Which is mainly due to me using mineral nutrients which I’m not used to and some PH lockout. My soils PH is fluctuating too much for my liking, so I just have to keep an eye on it as we go forward. I only feed every 3. Watering right now. But I’ll raise it slowly. Day 35 = 1,5ml Bloom, 1ml PureZym Will add Green Sensation when stretch stops. Time cycle back to 20/4 after I got humidity under control. Plants also looks like they are getting too much light beside rapid transpiration. Can’t measure how much PPFD though, so I’m going based on feeling and instructions from Spider Farmer which isn’t optimal offcause. Day 36 I have some kind of problem. And I think it’s light stress. And I also think I did damage to the plants with it. Hope they will bounce back. Flowering going slow Day 37 I think the night temperature of my grow has gotten too cold and my readings havnt been correct. Maybe under 19c which may also have been too cold for the plants, so now I made it rise to around 20c. Beside that, Im pretty sure I lightburned and light stressed my plants by putting another 100w in when their flowering began. They were not used to it and I shocked them. Looking back, I should I have started with the lights way higher than I did. But I dont know the height I should have used. But now Im trying with around 45cm to the highest of the plants since I have 200W for a 20/4 lightcycle. Will update when and if I see changes. F*%# While I was defoliating and doing LST, I accidentally topped one plant (the most bushy). As if I hadn’t already stunted them enough and made things hard. Now I’m sure it won’t be as good as I expected. I will keep it going for now but I may take out one or two plants and start over with one or two new ones. Cause I fear I ruined this grow with the lightburn and the envoirment switch I did moving into flower. I know I would be able to do much better with a new run. But I have to finish them if It makes sense, so I will see the next week, what I should do. Atleast I learned some things about my current setup and what to do and especially what NOT to do. Day 38/39 Thanks to @Enochian I now have a somewhat reliable chart for how much light im supposed to give my plants which I will try to follow from now on. The plants is also looking healthier now. LUX PPFD (μmol/m²/s) 5.000 92.5 10.000 185 15.000 277.5 20.000 370 25.000 462.5 28.000 518 30.000 555 35.000 647.5 40.000 740 50.000 925 60.000 1.110 And this is currently about what I get from my light level now: Final Results: PPFD 555 μmol/m²/s DLI 39.96 mol/m²/day Raised the feeding to 2ml Bloom and 1ml PureZym pr 1L water Day 40 They are recovering and making small bud sites. White pistils are showing. I raised the lights to 45cm again since they don’t seem to like too much light. I checked my PH and PPM and they were both a little too high. So maybe that’s why I have some nutrient problems since there should be enough food for them but they still pretty light green in new growth. (DLI): 34.6 (PPFD): 481

Scandic Day 42 (Plants look more yellow on the pictures than they are IRL but first picture shows their real colour better) Flowering has begun for real. I still have alot of things to worry about but they are enjoying life more now for sure. They are all very hungry, so I will give them more from now on but still trying not to overdo it. But the biggest plant really needs nutrients, maybe even some nitrogen. So i may give that one about 0,25ml pr Liter of Terra Grow. The others will only get Terra Bloom and PureZym. Will add Green Sensation soon too. PH was a little high when I checked runoff, so i will now give them 6.2 PH instead of 6.5. Watering: I have not had a good watering cycle for these plants in this grow. I normally use smaller plastic pots and so I think I have overwatered after I had problems with my PH. I gave them 3-4L of water each time, they needed water, to get alot of runoff but I dont think they have liked it. Now I give smaller amounts 1L-1,5L and more frequently and I think thats better cause now they dont droop the leaves after being watered. Then I will only get runoff 1 time per week when I will give them 3-4L to make sure salts aint building up too much. Nutrients: Im spoon feeding them at this point. Some of them wanted way more food than the others and im always careful with Nitrogen but this time I was too safe. So now im making sure they have enough for the most important phase. Blooming. Which means Ive had to give them a small amount of Terra Grow to supplement their feed. And Green Sensation will be added next week I think. Or maybe later this week. Estimates of DLI and PPFD: (DLI): 34.6 (PPFD): 481 —- After using chatGPT I have found out that I probably have to raise the lights further around 40-50cm above the canopy (50cm to all but the biggest which is closer to 40cm under but in the Corner. I have uploaded two pictures which explain my PPFD. From AI: "At 55 cm, your canopy is still getting: ~700–800 µmol/m²/s in the middle ~500–600 µmol/m²/s in the corners That’s well within the ideal flowering PPFD range (600–900), and because you run a 20h cycle, the DLI is already plenty high (≈ 35–40 mol/m²/day)."
