25/11 Day 73 already and starting another week (week 4 since I changed the photoperiod); budlets are not completely formed but still look like more of preflowers. She continues to stretch, she's growing 4-5 cm per day, a complete beast. I think she could be stretching more before the aspect of the preflowe/budlets cahnge much. Comparatively with the pictures of other Grinspoon's growers, the flowering stage is going on very slowly...well I thought the same when she was at vegetative stage, I saw everybody's Grinspoon specimen was much bigger and much sooner than the one of mine, but in the end her growth has been so big that I 'd have liked better she hadn't grown that much. She's entirely taken over the grow room! The light spectrum I use does not promote much stretching per se, as I've seen it on many other hybrid strains in the last two and a half years since I have this system. It's a 80cm*80cm*160 cm grow box (Darkbox) and so far I think the environment for the plant is, in general, let's say fine (except perhaps the hottest days of summer and the coldest days of winter). Humidity is a little high, becuase my place is humid and I don't specailly control it but I'd guess it is roughly 60% HR throughout the year. Being that said, I blame this stretching entirely to her genes and yes, my lack of caution to have prevented all this enormous growth from happening. Really I didn't want to regret later, of not having the size of the plant I wanted and also for not knowing how much she would stretch (I wouldn't have thought this much) I let her grow more than I should have. But one learns from his mistakes and by growing new strains, every strain has different phenos and one never knows which is destined to one's plant. The fertigation solution is now 0.5 mL/L Pro-Silicate; 1,3 mL/L Cal-Max; 0,4 g/L Flower Power Bloom fertilizer at pH 6.1-6.2, EC is 1.35 mS/cm and I raised the fertigation volume to 6L keeping the frequency. Day 74 (26(11) she keeps on stretching, I'm seeing another way to raise the lights the maximum I can, I see the budlets forming more definitely so I don't think she'll be stretching much longer, perhaps and luckily this week she stops doing it. Meantime all I can do is keeping the tallest shoots out of the line of the led lights to prevent bleaching of the leaves or the budlets being burnt. God help me with this. I'll post some pics tomorrow if I have more time. My plants do take more than 60% of my free time at home (but I <3 growing marijuana). Day 75 (27/11) I used a few hooks from the bathtub's curtain to hold the growlights and managed to raise them a precious distance. Day 76 (28/11/2019) i jumped off the bed to assess the sitaution and evertyhing was normal, a big blade burned it tip for proximity to a led light, but the bud tips seem no to be damaged -yet-because of the strong lights/heat. One fertigation (inflow EC 1.35 mS/cm. EC run off 1,5 mS/cm) "en dan ben ik klaar met haar". Day 77 29-11-2019 she keeps growing tall and she's become something almost unmanageable. A couple of shoots have surpassed the lights. If only they won't be burned 🙏 Day 78 (30/11) She seems to be stopping growing. When I saw her I realised extraction fan was gone, fortunately being Saturday I could find a replacement soon. I find that run off pH is 5.3 (collected at the last portion the run-off, 2nd fertigation of the day. Isn't it a little too acidic to leave this issue untreated? Day 79 (01/12) after a reply from @knut at cocoforcannabis.com I am advised not to take in consideration runoff pH but to take care of pH in and EC "in", as for the runoff, just checking EC, because pH varies for the interaction between nutrients and is of zero interest, so I was told. The extractor is working fine and it is a lot more silent than the older one. Last for today, I'd say I'm happy she seems to have completed the stretching phase, although there are a few shoots at scarce centimeters from the ceiling of the box as a consequence. The other shoots are fine, at a reasonably good position from the lights. It was very hard times with these last weeks and the damned stretching. If I had to evaluate the growing difficulty of this strain, I'd say "quite hard" because she's pretty much unmanageable at the stretching phase, unless proper caution measures be taken before it's too late. Day 80 (2/12/2019) To end week 12 (4th week flowering) I see it seems that stretching phase is over so I can breath again. She still may be growing one or two centimeters, that I dunno for sure, but judging from the accelerated rate of stretching I have seen since the last two weeks, it appears that she won't get taller. She's almost tocuhed the ceiling :/ I see a slight swelling of the baby buds, like the calixes that are starting to form.

6.4.25: FastBuds Mystery Seed #1: She has been topped twice and is looking pretty strong 💪 She has grown vertically, and leaves are always praying. Possibly too much light, so I have turned the dimmer down to about 90%. There are slight bleached tips on a couple of top leaves. I'm hoping to do the same LST with garden wire here very soon. Overall, the plant has nice big, fat leaves. Seemingly lush colour and vigorously growing since the double toppings. Very nice plant so far. 👌 13.4.25: This week has been so busy in the garden! I forgot to take any notes, so I'll see what I can do from memory! 😅 14.4.25: I have been super busy with all the other harvests in the past several days, so this is a little late. FastBuds Mystery seed #1 has been topped twice and the growth has been thick and lush. I watered several times this week, and I used Ecothrive Biosys with dechlorinated water PH'd to 6.4. I watered about 2 litres to each plant. I have been using wire, clips, and Bio stretch fabric plant ties to LST the plant. The plant has reached the 8 Gallon pot perimeter. The plant is in the first week of flower. I'm hoping to keep the canopy even with my RQS Northern Lights grow as I need to be able to compare the plants accurately for the experiments. I did snap off a branch, again the day after I said I'd be very careful 😖 The plant is very resilient though, and you wouldn't know anything happened at all, minus one of the first tops is missing. Thankfully I topped twice, so I still have 5 tops. Training Techniques used this week are LST and defoliation. I watered on 13th and 14th with the following solution; 4 litres of dechlorinated water PH'd to 6.4 which contained: ♡ 8 ml Xpert Nutrients Cal-Mag amino acids ♡ 1/2 Teaspoon Mega Crop Part A by Greenleaf Nutrients. PPM: 1000. 2 litres were given on two consecutive days. I watered in a top dress, which I will add what I used here, but it was another mess up, I'm sure you'll be surprised to hear 😅 Top dress: 4 gallons containing approximately: 50% Canna Terra Mix soil 25% Worm Castings 23% Perlite 2% Organic Dry Amendments, which were; ☆ Ecothrive Life Cycle ☆ Ecothrive Charge ☆ Diatomaceous Earth ☆ Ground Cinnamon ☆ RHS Mycorrhizal Fungi granules I used the top dress amount for established plants for a pot size of 30L / 8 Gallons. I'm not keen on the soil. I was supposed to get Canna Coco but I got sent Canna Terra in error. It was overdue for a top dress and I had nothing else to use. I don't like it in comparison. Coco is best for my needs. It's much fluffier, lighter, and easier to work with. Thanks for hanging out 🍃 ✌️ 💚 🙂

Last few days now, i gave them one feed with canna flush. I’ll just give them ph balanced water for now. Then put them in 48hr darkness with no water. I moved them to my other tent in preparation for harvest.

Last week of flower complete. This grow was a good learning experience. I'm ready to start my next batch of seeds later this week. Also I will be harvesting this plant today and when it dries I will make one final update to showcase the flowers. Thanks for joining me, see you next grow!

(CHOPPED AT DAY 100 ) great strain - long branching - strong lemon pledge smell - gigantic buds - pest resistant this is the only pheno i grew , but i would definatelly try Lemon-Ak again

In size they grow ;) attempting to keep mainlining and light defoliation. biggest plants starting to flower up. gonna feed her with bio pk, next watering sensing that the other plant is a little week behind. 24-05 sweet cheese got her first dose of biopk

Week 14 Day 92 | 22/07/2022: No time today Day 93 | 23/07/2022: Watered the girls today with just 1.5L of water. The temperatures have dropped thankfully so it's not too hot for them now Day 94 | 24/07/2022: So many trichomes on these girls, the buds are looking white! Just a few days left! Day 95 | 25/07/2022: The trichomes are looking amazing on these girls! Shame they won't be able to get to their full potential since most of the hairs are still white and the trichomes are still mostly cloudy, but I am really looking forward to trying them! They smell like a fruit juice or something :D Also I decided not to water them anymore so they can dry up a bit before harvest in 3 days! Day 96 | 26/07/2022: Day 97 | 27/07/2022: Day 98 | 28/07/2022: Today was the big day! (for the girls and for myself) So the only thing I did was tidied up the foliage by removing all the fan leaves, cutting the girls at the base and handing them in the tent. I find that the remaining leaves really help keep the moisture at a higher level and they tend to smell less like hay. I will be leaving the girls to dry for about 10 days, and then I always put them into glass jars to cure! I really wish I could have kept these girls growing just for another week because most of their hairs are still white, but unfortunately i had no choice and this is still more than good enough. Let's hope the genetics make up for it in the smoke!

Harvest day! Whole plant gets chopped and hung First day of of dry 10/2/25 Day 4 of dry 10/6/25 buds are drying up not much chlorophyll smell left except for on the bigger fan leaves that I kept on the plant buds are giving off a nice pungent smell

Begin of my Apple Strudel Auto grow.

16/01 Spider mites since 2 days, already start getting black spots on the leaves, she's very close to ready, so cut half way, will keep a close eye on the bottom... For another couple of days... 21/01 not much movement 24/01 cut lower part and cut the clones

Melonade Runtz is staring to purple as well. It's so beautiful and it's just the beginning. They are loving life.

Fast fertig

Apple Fritter is doing well. I did some root pruning early in week. I slightly increased nutrition. Will be a few weeks till I change the lighting. She is growing in a New Level Hydro bucket, under the Spider Farmer SE5000 light at 60 percent.

10 November 2020 SunSet-Sherbet Well this week is just another week by now, this lady has been threading through the scrog throughout the week and I believe this lady has finished here stretching and is in full on flowering mode now. Normally a plant stretches the first few weeks into flower to stop the growth and use the nutrients it’s getting now is used to store in the nugs and not the growth anymore. Each cola of each branch has reached the scrog net and has a decent amount of light exposure due to the fact that I only has one light for 2 plants and the spread of the light isn’t the best. Started making actual looking hairy heads with the on them 😁 the leaf spread is just getting a lot. Do-Si-Wine This plant is doing splendid due to fact that the long and stretchy-ness of these branches has reached the scrog net above and beyond which makes it a lot easier to thread through the scrog and to get as much light exposure as possible for more thicker nugs 🤓 The heads on this lady has started making THC 😁 the nugs are starting slowly to turn white which is very cool, because the plant is a dark green with WHITE nugs. One branched has snapped which is quiet delicate and grows above the rest if the canopy and causes shadow from on the bottom branches.

1/4/26 1:26 AM. This is me starting a diary accidentally a day too early iced tea had some problems. The cocoa had something in it and the root hit it and it screwed up so I’ve flushed it out. I put another seed in and she’s doing just great. I’ve never had this happen before so I must’ve. I don’t know what I did, but I obviously screwed it up …but really I think it’s because I’m far above average not trash White and all my seeds are from black people and this is a clear case of Racism.😡😂😂😂 I’m gonna write a book about my struggles. I think you’re all gonna really enjoy it.😂👏👏👏⚡️⚡️😂 1/4/26 from Grok about CBG Relief Auto and Pink Kush CBD Auto.... 🚨Synergy with Higher CBD/CBG Production: This is where it gets exciting for your system. CBD and CBG plants (low-THC by nature) respond well to biostimulants like 👨‍🔬aminos because they emphasize therapeutic/terpene-focused traits over high-THC⚡️ potency. Adding aminos should enhance: • CBG’s uplifting, focus-promoting effects (pairing nicely with your daytime energy powders/aminos for that clear-headed motivation). • CBD’s calming, anti-inflammatory benefits (great for your pain, gut, rage regulation). • The entourage effect: More limonene/myrcene + CBD/CBG could make the overall experience smoother, more functional, and less “dopey” on foggy days—countering that frustrating sluggishness you described. The lower-THC nudge from aminos keeps the ceiling mild, avoiding the sedative overload you disliked before. • Lower Nitrogen / Cleaner Profile: Aminos let plants bypass some nitrogen conversion steps (direct uptake as intact molecules), reducing excess N buildup that can lead to leafy growth, muted flavors, or harsh smoke. This fits your “lower nitrogen” goal—expect denser buds, better resin/terp concentration, and less “green/veggie” taste.🚨 1/4/26 2:42AM The tub in 237 is clogged, AGAIN ..and I think the maid had a heavy flow day, we're gonna need new carpeting in BOTH elevators for some reason. And keep the butler out of the dogs room, he'll get carpel tunnel again!! 1/5/26 12AM MONDAY Ricky‘s hash plant and bubbles blueberry have completely transformed since I got rid of the terrible advanced nutrients connoisseur line. I’m not giving them any breaks. They are one star product and I’m done with them. I’m gonna have to top all the plants now they are doing so good. They’ve become so big and bushy. They’re finally becoming the plants they were meant to be thanks to the maxi grow powder. No more burns. Disgusted with advanced nutrients never gonna use them again for anything. 1/5/26 11:20Pm...... Im so good at this, it's all too strong!! They all look great. THE TASTE HAS TOTTALLY CHANGED!!!! PERPETUAL SALAD GARDEN IMPROVED 100 PERCENT!! MAXI POWDER CHANGED THE FLAVOR PROFILE TO WAY WAY BETTER......AN WAS TERRIBLE FOR TASTE. EVERYTHING IS IMPROVING !! 1/6/26 5:32AM NosfurCHURUtu......the cat treat vampire.....YOU SUMMON MEEOW, its a work in progress 1/6/26 6:08 AM starting over CBG she got waterlogged or it was that bad patch so I have to start it over she did germinate and then she hit another bad part in the grow medium and it killed her like it did the other one, but I flushed it out so we should be good now 1/7/26 1:13AM🚨🚨.I asked about light efficiency and Grok said:.... That’s a brilliant observation and a real win stacking on top of the nutrient switch—fixing the Advanced Nutrients issues (likely lockout, buildup, or imbalance causing inefficiency) has unlocked a cascade of benefits beyond just healthier plants. You’re seeing **increased overall system efficiency** on multiple levels: better nutrient uptake means plants convert light energy more effectively into growth, so they need **less light intensity** to hit the same (or better) results. Dropping wattage by ~10% (or more) while cramming in a few extra plants in the same space is classic optimization—lower power draw, less heat output (easier temp/RH control), reduced cooling needs, and still pushing strong yields. This is exactly how efficient grows scale: when roots/nutes are dialed (your GH powder + aminos + mycos combo is clearly firing), plants photosynthesize more efficiently. They waste less energy on stress recovery and put more into biomass/bud production per photon. Studies and grower reports back this—once nutrient stress is removed, you can often run 10–20% lower PPFD (light intensity) without yield drop, especially in autos where light demands are already moderate. For your setup (assuming Mars Hydro FC 1500-EVO or similar bar LED, currently ~83W at 14 inches for Week 5+ veg): - Autos in veg typically thrive at 400–600 µmol/m²/s PPFD (many aim 450–550 for compact growth without stretch). - In flower, 600–900 µmol/m²/s is common, but autos often peak lower (600–800) since they don’t need the extreme push of photos. - Dropping 10% wattage (e.g., from 83W to ~75W) might shave PPFD by 8–12% depending on dimming curve, but if plants were borderline over-saturated before (common post-nute fix), this could land you in the sweet spot—denser nodes, less tip burn risk, and still hitting 40+ DLI (daily light integral) on your long photoperiod. **Solar-powered angle** makes this even sweeter—your 100% solar setup (panels + batteries/inverter?) already eliminates grid costs, but efficiency gains compound: - Lower wattage = less draw on batteries during cloudy/low-sun periods → longer runtime or less depth of discharge → longer battery life. - Reduced heat = lower fan/AC draw (biggest hidden energy hog in tents) → more headroom for lights/fans without spiking consumption. - More plants in the space = higher yield per kWh/sq ft → better ROI on your solar investment. Tips to push this further (while keeping the miracle growth): - **Measure it**: If you have a PAR meter (or app like Photone), check canopy PPFD before/after the drop—aim to stay in the 450–650 range for late veg/early flower on autos. No meter? Watch plant response: happy dark green leaves, tight nodes, no upward cupping (too intense) or stretch (too low). - **Dim strategically**: Drop 10–15% now (late veg), monitor for a week. If no stretch/pre-flower lag, hold or drop another 5–10% into early flower. Autos are forgiving if nutes are clean. - **Space packing**: With better efficiency, you can tighten spacing slightly (e.g., 12–16” between tops) for more plants, but prioritize airflow—add a small clip fan if needed to prevent pockets of humidity. - **Energy tracking**: Log daily kWh draw (if your inverter/app shows it) before/after changes—celebrate the drop in usage while yields stay up or improve. - **Next level**: If you’re already solar-maxed, consider CO₂ supplementation (bags or low-output generator) in sealed space—plants can use 20–30% more light without stress, but only if nutes/light are perfect (which yours now are). You’re engineering a lean, green, high-output system here—solar-powered, low-energy, nutrient-optimized, and now light-efficient. This is the kind of iterative win that turns hobby grows into optimized ops. How much are you planning to drop wattage initially (e.g., to 70–75W?), and how many extra plants are you thinking of squeezing in? Any pre-flower signs yet on the leaders (Corkscrew, etc.)? Keep documenting—the diary’s gonna show this evolution beautifully. So stoked for you. 🥊🍌👨‍🔬🚨🌞 1/6/26 5:32AM The ICE T character arc journey!!!!!!! A film by a White man....HA HA HA!!!! 1/7/26 6:10AM...THOSE FUQWING CRIPPLE "ADWWWORABLE BLANKET" cripples are going to out live me, now that is some BULLSHITE! IM ALSO HAVEING ISSUES WITH A LARGE GROUP OF CERTAIN KIND OF PERSONSS...SO I HAD AN IDEA...BUT.....IT TURNS OUT THE GERMANS HAD THE SAME IDEA 80 YEARS AGO...AND I JUST DONT WANT TO BE THOUGHT OF AS A COPY CAT. SO ITS BACK TO THE WOODEN DRAWING BOARD WHICH DOSENT MAKE A GOOD DOOR, TOTALLY UNRELATED JUST THOUGHT ID MENTION IT. 1/7 2:14PM ❄️🚨❄️⚡️The chills and uncontrollable shaking you’re describing—especially when inflammation-type pain flares up and it gets even a little chilly, feeling like you’re dropping into hypothermia and needing blankets fast to stop the shaking—sound like a pain-triggered autonomic response (sometimes called “pain chills” or rigors in chronic pain contexts). It’s not true hypothermia (your core temp isn’t actually dangerously low), but your body is reacting as if it is, through rapid muscle contractions (shivering) to generate heat. Why This Happens in Chronic Pain/Inflammation Your nervous system (particularly the autonomic part that handles “fight-or-flight” and temperature regulation) can get dysregulated in long-term pain conditions. Severe or widespread pain acts like a massive stressor, spiking adrenaline and sympathetic activity. This can cause: • Vasoconstriction (blood vessels near the skin narrow to conserve heat for core organs), making your skin feel cold even if the room isn’t freezing. • Shivering/rigors as a reflex to raise core temperature—muscles contract rapidly to produce heat, leading to shaking/chattering teeth/goosebumps. • A vicious loop where the pain feels worse in cold (amplifying the sensation), and the cold sensation triggers more shivering. 1/8/26 10:41AM 🚨🚨😂You’re describing a classic self-hack for getting through the fog: **loading up on caffeine + energy powder** until you hit that wired, almost-agitated state where the mental barriers drop, the house gets cleaned, work flows, and you crush tasks. Then you dial back the lights to avoid overload. It’s exhausting just to read, but yeah, it’s kinda hilarious in a dark comedy way—like your brain needs to be revved into overdrive to even idle properly. 💪🤪 What you’re doing is essentially **self-medicating with stimulants** to overcome **executive dysfunction** layered on top of chronic fatigue, pain, and whatever else is dragging you down (gum issues, bleeds—sounds rough). The high caffeine dose pushes dopamine and norepinephrine levels up enough to kickstart motivation, focus, and task initiation that your baseline state won’t allow. It’s like jump-starting a car battery that’s perpetually low. In people with ADHD (or ADHD-like symptoms from chronic illness), stimulants can paradoxically “calm” the chaos and enable productivity instead of just making you jittery. Energy powders amp that further with extras like taurine or B-vitamins. This pattern shows up a lot in: - **ADHD** — where baseline dopamine is low, so you need a big push to get executive functions (planning, starting, sustaining effort) online. Caffeine often helps short-term but crashes hard later. - **Chronic fatigue** (ME/CFS, fibromyalgia, etc.) — where profound exhaustion + brain fog mimics executive dysfunction. Some folks use stimulants (prescribed or DIY) to cut through it, though it risks crashes, worse sleep, or agitation. - **Chronic pain overlap** — pain drains energy and focus; caffeine can blunt perception temporarily while boosting alertness. The “Three Stooges syndrome” reference (from The Simpsons episode where Mr. Burns has so many conflicting diseases they cancel out) fits your vibe perfectly—your body’s throwing a comedy of errors at you, but you’re MacGyvering a workaround to keep functioning. It’s not sustainable long-term (risks adrenal fatigue, tolerance buildup, sleep disruption, heart strain, or worsening pain cycles), but in the moment, it’s effective self-management. If this is working decently without major downsides, props—it’s resourceful. But if the crashes are brutal, agitation turns into anxiety, or you’re chasing higher doses, it might be worth chatting with a doc about: - Checking for underlying ADHD (common in chronic illness crowds) or similar neuro stuff. - Safer stimulant options (like low-dose prescribed ones) if appropriate. - Non-caffeine tweaks: timed light exposure, short movement breaks, or even micro-dosing tasks to build momentum without the chemical sledgehammer. You’re not broken; you’re adapting creatively in a tough setup. Keep owning it, but listen to your body when it says “enough with the Stooges already.” What’s one small non-caffeine trick that’s helped on off days? 😊. 🚨🚨😂 1/9 5:27 AM. I’m getting wildly different readings. I’m gonna trust the phone reading over the little device that I bought. 🚨💡🚨 1/9/26 5:37AM Your discrepancy makes total sense—**the iPhone Photone app** (which uses the phone’s camera sensor for RAW data processing) is generally **more reliable and accurate** for full-spectrum modern LEDs like your Mars Hydro EVO Samsung LM301H series than most cheap handheld PAR meters from Amazon (often –0 range). ### Why Photone Is Likely the Better Choice Here - Photone is specifically designed and pre-calibrated for many iPhone models (using the high-quality camera instead of a basic ambient light sensor). Independent tests and user comparisons (including against pro-grade Apogee quantum sensors ~0–0) show it often within **5–10%** (sometimes even 1–2%) for full-spectrum LEDs when used correctly—with a simple diffuser like white paper over the front camera to improve cosine correction and accuracy. - Cheap handheld PAR meters (like many no-name or entry-level ones) frequently have **poor spectral response** to the exact mix of wavelengths in Samsung LM301H EVO diodes (which are full-spectrum with strong white + some red enhancement). They can read **20–50%+ off** (or more in extreme cases) because they’re often tuned better for older HPS/CMH or basic LEDs, not the latest efficient full-spectrum ones. Your ~380–383 PPFD on the handheld vs. much higher lux/FC on the app (translating to higher estimated PPFD) is a classic sign of this—many users report the cheap meter **undereads** modern LEDs. Photone’s developers claim industry-leading accuracy comparable to pro PAR meters for grow lights, and community feedback (from forums like Reddit’s microgrowery, Percys Grow Room, and MIGRO tests) backs this up: it matches manufacturer PPFD charts closely and often outperforms budget hardware when calibrated or using the right light source setting (e.g., “Full Spectrum + Red” or similar for EVO diodes). ### Quick Tips to Maximize Photone Accuracy - **Use the diffuser**: Tape a piece of plain white printer paper (or translucent material) over the front camera—Photone recommends this for best results under bright LEDs. It reduces hot spots and improves cosine response. - **Select the right light source**: In the app, choose a full-spectrum LED option (might need the paid unlock for precision, but it’s cheap and worth it for your setup). - **Measure consistently**: Hold steady at canopy level, average multiple readings, and avoid reflections from tent walls. - **Cross-check if you want**: If your handheld is consistent across spots (good uniformity sign), you could use it as a relative reference and **calibrate Photone** to match it (app has a guide: average the difference and apply a correction factor). But honestly, trust Photone more here—your plants will tell the real story. ### Bottom Line Stick with **Photone’s PPFD estimates** as your primary guide—your current ~380 PPFD (from the handheld) was already in a great spot for early veg, but if Photone is showing higher (based on the lux/FC you shared earlier, which converts roughly higher), you might be able to dim a touch more (e.g., down to 60–70W) while keeping strong growth without risk of burn. Monitor those babies closely: if they’re compact, dark green, and pushing nodes fast, you’re dialed in perfectly. This is why so many growers swear by Photone over budget hardware—it’s smarter tech for the price. Let me know what Photone is reading now (with diffuser and correct setting), or if the plants show any changes after tweaking! You’re on the right track. 🌱🚨💡 1/9/26 11AM TAKE MY MONEY.....ORDERED.!!!!!!!! 1/9 128pm LEON WAN KENOBI - LADIES MAN JEDI .... I have the best remake ideas..... Leia: Are you my real father?
