Just planted first seed (1/23/20). Germinated in paper towel after 16hr soak. Seedling planted with 1/2" long tap root. Soil is straight, out of the bag, FFOF in 5 gallon pot. Initial watering with about 3/4 gallon of distilled water. Light schedule is on 6am to midnight. Using a 2 x 2 grow tent. I have no idea what I'm doing with ventilation. Have side vents on tent partially open by making a 'V' at bottom and am running fan at about half speed on dial.. Seem about right as slight negative pressure when closed up. Also running heat mat under pot and space heater inside tent to keep temperature above ~64*F as tent is in room that runs cold in winter during evening (~45*F). Temperature with everything on seems to stay within 68-78*F. Also running small 6" fan in bottom of tent to circulate air. I'm not sure what I'm going to do about LST, topping or defol yet.
Update 1/25/20: Sprout appears. Woot! I also had to scramble to replace the "Numifan 500W space heater" I was using as it failed in the middle of the night yesterday. I had a larger 750/1500W space heater on hand and used that while waiting for replacement from Amazon. This caused pretty wild temperature swings in tent as heater turns off and on with thermostat...as much as 20*! The Numifan 500W was bad enough at 10* swings. This morning I received a new "LIFE SMART 350W Mini Wall-Outlet and Table Portable Electric Handy Space Heater" from Amazon. This one is the bomb! Much tighter on the thermostat with temperature swings only a couple degrees! Now able to maintain solid 76* in tent 24/7. Also no more wild swings of humidity caused by heater. Humidity is now holding at ~36%. I may still need to add a humidifier but I'll hold off a bit.
Update 1/29/20: Everything seems to be going smoothly. I am struggling and stressing over when and how to water. I have not watered for 3 days. I will probably give some water today. I'm also tracking temperature and humidity. I've got the temperature dialed in but the humidity is low at ~32%. I will probably be buying a small ultrasonic humidifier to put in the tent.
1/31/20 - Seeing a little growth every day. No idea what I'm doing with watering yet. I haven't watered for 3-4 days and soil still seems moist about an inch down from surface. I have also been misting top of soil and plant with water the last 3 days...mainly because humidity is so low. I'll likely be picking up a small ultrasonic humidifier in the next few days to see if I can improve things. Watered 32oz. (6.6Ph) today.
2/2/20 - Still growing :) I tried a small humidifier and it did work pretty well but it was not big enough. Only got humidity up to 38% and ran dry in 4 hours. I'll be returning it for a bigger one. I'm also a little confused about venting the tent. I have small flaps at base of tent I opened two of them by tenting the bottom of flap slightly, making an opening where direct light can't get in but air can. I think this really hurts my heating and humidity control efforts but plant needs fresh CO2, right? I'm running the vent fan (configured as exhaust) at about 33% speed with the carbon filter inside the tent for extraction. Any suggestions or explanations for how to set vent flaps?
2/3/20 - Watered 16oz. I also closed one of two vent flaps and lowered fan speed to minimum. Per advice received from my question, I am puzzled by the answer to close all the vents with the vent fan running. Not much change noted on temperature or humidity after a couple hours. Still waiting for replacement humidifier.
2/4/20 - Got my new humidifier. This one has built in humidistat and 1 gallon tank. Filled with distilled water and put in tent. Seems to be working well.
2/6/20 - Humidifier working great. Plant is doing great! (or so it appears to me) Starting to notice a slight odor now in the tent when I open it. Still trying to get a handle on watering. Soil still seems moist. on top because of the humidifier?
What to do with vent flaps at bottom of my 2 x 2 tent? Exhaust fan running at ~33% speed with carbon filter in tent as intake. Tent In cold room (overnight temps 45-55*F) , running heater and humidifier in tent. Currently, 2 of 3 flaps tented at bottom of flap to allow air in.
I would close them to keep the heat inside. At this point there isn't much need for them to be open unless you have heat issues and wanted the cooler outer air to get in the tent.
2/7/20 - Pretty happy so far.. Both me and the plant. :) Seems to be growing fast now. I closed all the vents and left exhaust fan running (on lowest setting) so there seems to be significant negative pressure in tent but I read that that can be a good thing. I will let it go for a while like this and see what happens. This should be my last week on just ph balanced water as I plan to start the nutes next week. I'll be using FF Grow Big for veg nutes and FF Tiger Bloom for bloom nutes when the time comes at a reduced level from FF recommended. Watered 32oz. today.
2/9/20 - Looking good I think. Watered 32 oz. today
2/10/20 - Growing like a weed!!! Measured 4" tall today and working on its 4th node. I really have to figure out how to do LST.. This is short tent and I need a short plant. :)
2/11/20 -Plant is noticeably odoriferous now. Studying LST techniques on youtube. 4th node is established...as soon as 5th node pops, I'll bend main stem over and see where that takes me after a couple days.
2/12/20 - Growing fast. I'm astonished how fast this is going but acknowledge there's still a long way to go and a lot to learn. Watered 32oz. today.
2/14/20 Getting big! Started LST today. First step was to tie bottom of plant stem to stabilize it when I pull over from top. Second step was to bend stem over and tie to pot. Stem is getting very big and bending it is no longer easy. This makes me afraid of breaking it. I'm going slow and will make adjustments over the day to bend more and more as plant relaxes. Starting veg nutes this week.
2/15/20 Watered 32oz. with 1/2 veg nutes and adjusted my tie-down to main stem. I knew things were going too well... I broke the main stem. Not in two but about 2/3's of the way through. I taped it up with stretchy medical tape and a toothpick and it looks secure but I dunno. I may have killed it. At this point, I'll be happy if it lives. Will monitor closely and keep my hands off I guess. No more training. Damn it! 😬
2/16/20 Treating it with kid gloves... 24 hours after the break, it still looks good overall. Couple of wilted fan leaves and branches that were near the break may not make it (should I just cut these off?) but the rest of plant looks healthy for now. Even though I abandoned LST, plant has straightened back up a bit but seems to be growing out rather than up... This is good for me I think....this is a short tent with a sativa dominant strain. I'll take it.
2/18/20 Still looking good. Watered 32oz. with 1/2 veg nutes. I cut one of the wilted leaves off...the other seems to have recovered. I'm still unsure about trimming/pruning.. When should I start?
2/20/20 Looks like plant is flowering to me. Supposed to be white pistils showing up and that's what it looks like to me. The pistils appear whiter in person than in pictures. Next week, I'll switch to 1/8 veg and 1/8 bloom nutes. It's growing so big that I'm tempted to start LST again...maybe just try to tie branches to side a bit.
2/21/20 Really stretching out now. Watered 32oz. with 1/2 veg nutes. Tucked a few leaves.
2/22/20 Soil seemed dry and pot light. Watered again with 32oz. w/ 1/2 veg nutes. I guess this growth spurt is using up some water! Will switch to 1/8 veg and 1/8 bloom nutes tomorrow or next day. Raised light a bit since plant getting tall. Really getting bushy and probably need to defoliate a bit. No idea how to do this really but I think it's safe to cut off the old bottom growth that's almost in the dirt. My taping and splinting of the main stem break I had last week is holding up and stem seems strong. I also have to research and find out when I can remove tape and splint.
2/23/20 Watered with 32oz. w/ 1/8 veg nutes and 1/8 bloom nutes. Soil gets dry fast!
2/24/20 Plant looked a little droopy this morning and soil seemed dry again. Pot felt light also. Watered with 48oz 1/8 veg nutes and 1/8 bloom nutes. Can't believe how the water usage has gone up! I need to stay on top of this. I also noticed that the first full leaves (2) at bottom of plant were either in the dirt or close to it. I trimmed them off.
2/26/20 Looking good I think. Leaves kind of look droopy to me but I think its normal because its much bigger. I need to be more careful mixing my nutes with water as I mixed up my tiger bloom and my big bloom. I think I'll just start using the big bloom every other watering at half recommended strength. Watered 32oz.
2/27/20 Closing out week 5... Watered 32oz trimmed a couple lower leaves. It's getting really tall. switching to 1/2 bloom nutes next week with 1/2 Big Bloom fertilizer also added. One plant has definitely filled out this 2x2 tent....not sure how people get more plants in there. I should have probably gotten 2x4 tent and bigger light. Oh well.. It's a start and I can't really complain about my success (luck) so far. 😉
2/28/20 - Watered 32oz 1/2 bloom nutes, 1/2 fert. Even after this watering, pot seems light. I will probably have to water more today. Plant is looking good I think. Getting tall so I had to raise lamp again. I should be able to remove splint this week..though plant doesn't seem to have suffered because of the break. Is two weeks enough time for plant to mend partially broken main stem?
2/29/20 - Watered (plain water) 48oz.
3/01/20 - Watered 48oz. 1/2 bloom nutes, 1/2 fert. Plant has pretty much filled up all the space in tent to grow out and it has grown up quite a bit. I have no idea how anyone could grow more than one plant in 2x2 grow tent. To optimize space a bit, I rearranged where fan, heater and humidifier sit on floor. This also helped with moving humidifier nozzle into corner so mist not blowing directly on leaves (for now anyway). I'm not sure what I'm going to do if it gets any larger.. there won't be any room for heater and humidifier to blow up and around canopy. I have pole mounted fan that's above canopy but haven't really used it much yet. Fan on floor has been working good to keep heat and humidity distributed.
3/02/20 - Watered 32oz (plain water). Seeing a little more every day. Rearranging heater, fan and humidifier seems to have helped with humidity and heat distribution. The telltale cannabis odor has been here for a while but only when I open tent. The carbon filter and fan are doing a great job keeping room odor to zero. For the first time, I noticed a distinct citrus smell on my hands after handling plant. 😋
3/03/20 - Watered 32oz. 1/2 bloom nutes, 1/2 fert. Everything seems to be going well.. I noticed that the bottom of tent seems to be warmer than the rest of tent (above canopy). I'll start running pole fan at top of tent during the day. Maybe the heat isn't making it above the plant growth which has pretty much filled up the entire width and depth of tent. A little more air flow should help. Might be time to crank open the tent vent flaps as well. Currently there is only one flap that is open slightly. It could also be that the plant is now contributing to the climate of the closed tent environment.
3/04/20 - Watered 32oz. (plain water). My nighttime (lights off) humidity is a little screwy now after rearranging everything....Have to make some adjustments in humidistat settings. 2x2 tent is F U L L . I have a little room to grow up not much for growing out. Lots of foliage at bottom of plant too.. Maybe these leaves could be trimmed? ..it would make watering easier at the least.
3/05/20 - Watered 32oz. 1/2 bloom nutes, 1/2 fert. Nighttime humidity a little better after leaving pole fan running all night. I also have 6" fan on floor that has been on since planting. The idea was to keep the air circulating around the heater and the humidifier. Looks like 4-5 good bud sites developing hard. Many others but they are not shooting up. Is this normal? I realize it's only week 6 and I'm probably not even at half way point yet. I have nothing to really complain about though. Pretty happy with this so far. 😎
Day 43 - Still going well I think. I decided to go with a bigger light. I'm currently using a Mars Hydro TS 600 but will be switching to a Mars Hydro TS 1000 this weekend. TS 600 was okay but now that some stems are really reaching up, I had to raise light and the light to the lower stems is getting weak. This should do it. Watered 48 oz. plain water.
Day 44 - Watered 48 oz. with 1/2 bloom nutes and 1/2 fert. I cut off the splint I put on 2-3 weeks back on my broken main stem. It appears to have healed up perfectly. hardly a scar visible. I also cut off a couple bottom leaves that were looking bad and yellowed. These were bottom leaves on the first side colas off the main stem.
Day 45 - Watered 32 oz. with 1/2 bloom nutes and 1/2 fert. Installed TS 1000 light. Lots brighter...Hope this makes plant happy.
Day 46 - Watered 32 oz. with 1/2 bloom nutes and 1/2 fert. Plant seems happy. This light is much brighter. Photos are more difficult because they are over-exposed. Looks like there are 5 main colas that have shot way up above the rest. Is this normal? There are many others but they seem to stick around the top of plant canopy. Hoping this light will make it to them and the can also shoot up? Maybe this is all normal with no training to speak of. I started LST but broke a stem and abandoned training. However, I'm not sure what difference it would have made... Plant is already wall to wall. New TS 1000 has also increased the temps ever so slightly but not enough to be concerned with. It gets a little warm on top of light but not really bad at all.
Day 47 - Seemed a little droopy this morning. Soil was dry and pot was light. Watered 48 oz. with 1/2 bloom nutes and 1/2 fert. I've been going back and forth between 32oz. and 48oz. but I think I need to stick with watering 48oz. at a time now. I'm also having a little trouble with humidifier in that the humidistat is in bottom of humidifier at bottom of tent and measuring device I track is at top of canopy. There is a difference in humidity levels at these two places and it's getting harder to keep this differential in check.. I also think this is because the plant is providing humidity to environment. I'm hoping that I'll just be able to eliminate humidifier at some point.
Day 48 - Watered 48 oz. PH water. Noticed some spots on some of the leaves. A couple of the lower leaves have turned a little yellow also but will probably be trimmed off soon. It's the spots on upper leaves that has me a little concerned. I'm watering every day now..Is this normal? Plant seems to want between 32 and 48oz. /day. With 48oz. 2 days in a row, I may have a little runoff show up in pot tray. I'm thinking light may be too much or watering too often is causing the spot. Should I not water every day?? I'm also having as little trouble maintaining heat and humidity overnight. During day when light is on, I'm seeing temps and humidity pretty stable at ~80* and 45%RH. When light goes off, temperature drops to a low of ~60* and humidity may climb to 70%. I think some of this is caused by dehumidifier and heater being in bottom of tent under canopy and monitoring/logging temp and humidity from an instrument mounted just above the canopy on side of tent. So maybe there's a thermocline right at the canopy? Could spots be caused by this temp and humidity variance?
Day 49 - I took photos to my local grow store and they advised that my spots were caused by a calcium deficiency and that it's pretty common problem using our city water. So, I bought a bottle of Cal Mag and started using it today. Watered 48oz. with PH water mixed with Big Bloom and Cal Mag. We shall see what happens. She looked pretty good this morning and doesn't seem to be stretching vertical as much anymore. The bud sites are really starting to really fill out though. I also trimmed a few more bottom leaves that were yellowing a bit. I'm still having to monitor humidity and temp carefully but I suspect with the weather warming up here and the plant being pretty fully developed that I wont have to worry about it too much longer.
I have no idea how much longer till harvest but time seems to be passing quickly and I better start figuring out what to do next.
Day 50 - Terrible start to week 8.. The spotting problem has gotten worse. I've only been able to treat with Cal Mag once (yesterday) and plant doesn't seem to need watering yet today but I may be able to squeeze a 1/4 gallon in later. I'm still proceeding as if this is calcium deficiency. Does anyone looking have any comments? I'm not sure what to expect after treatment and I expect spotted leaves will not fix themselves but I still do expect to see improvement at some point...like no new spotting. I will probably just cut off spotted leaves soon and watch for any new appearances. 😕 Watered 32oz. With Cal Mag.
Day 51 - Watered 32oz. with 1/2 Big Bloom and 1 Cal Mag.
Day 52 - Watered 32oz. with 1/2 Big Bloom and 1 Cal Mag. Trimmed a few damaged leaves. No *new* damage from calcium deficiency noted. Still a few older damaged leaves left but they are close to or in bud sites so I'm going easy.
Day 53 - Plant definitely worse this morning. Please help me figure this out. I took a leaf to local grow store and they think is pH problem. They advise to lower water pH to 5.8 and run full dose of Cal Mag with Big Bloom and Tiger Bloom. Up till now, I've been adjusting water pH to 6.6. Watered 32oz. 5.7pH water with 1/2 tiger bloom nutes, 1/2 big bloom and 1 CalMag.
Day 54 - Still looking worse. Watered 48oz. 5.7pH water with 1/2 tiger bloom nutes, 1/2 big bloom and 1 CalMag. I've been using CalMag and adjust water pH down. Also using nutes. I also opened left side vent at bottom of tent (right side vent has been open for weeks) Not sure what else to do. In case my issue is Rust fungi, I applied Safer brand 3-in-1 Garden Spray (has .4% sulfur) and shut light off for 4 hours in middle of day. I probably should have waited until evening.
Day 55 - Still looking bad. I stopped running humidifier at night on the chance that the high humidity and low temps were causing a rust fungi. This is all very depressing. If it's a calcium deficiency, I'm now treating with CalMag. If it's a rust fungus, I treated with sulfur spray. I don't know what else to do.
Day 56 - 48oz. 5.7pH water with 1/2 tiger bloom nutes, 1/2 big bloom and 1 CalMag. Noticing strange odor from plant which I think is from the Safer brand 3-in-1 Garden Spray.
Help! I thought I had this. Is this calcium deficiency? I've been using treated water (1tsp CalMag+ 1tsp Grow Big per gallon). It's just getting worse. See photos and descr. from past few days.
Hey man I just saw your question about harvesting...first the plant isn't ready to harvest yet. Your pistils really aren't starting to die off yet. You have several weeks to go from what I see. The damage on your leaves is a light or heat related issue. I would try to get the light as far away from them as possible so you can push them longer. Good luck!
Day 57 - Start of week 9; Plant has funny odor which I think is from the garden spray I used to combat rust fungus. Plant's appearance doesn't seem to be getting any worse now and it looks like I will be able to harvest (fingers crossed) soon. Maybe the worst is behind me. Watered 48 oz. pH 6.2 with CalMag.
Day 58 - Watered 48 oz. pH 6.2 with CalMag. Seems to be getting more yellow.. I'm completely lost. About a week or two ago, I started using new light. I went from TS-600 to TS-1000. Coincidence that problems started after new light? Since TS-1000 has adjustable light output, I turned it down to about 70% (I think) today.... Just in case this is some kind of light burn. Light is about 12" from closest nug and I cannot get it mounted any higher.. this is a short tent.
Day 59 - Watered 32 oz. pH 6.2 with CalMag. Not much change.. If anyone sees this, Can you estimate time to harvest from my current pictures? Thanks.
Day 60 - Watered 32 oz. pH 6.2 with CalMag. I know it looks bad but there's hope. I expect to harvest at some point at least. The buds seem to be getting fatter and they look pretty good except for the sugar leaves. They are getting crispy looking. Still no idea what the damn problem is. The whole plant is getting pretty yellow and I've trimmed a ton of leaves off...mostly crispy ones.
Day 61 - Watered 48 oz. pH 6.2 with CalMag. Is this ready or getting close to harvest? I just cant tell. Trichomes look to be a little milky and there appears to be some amber ones in there but it may be the grow light casting an amber color?
Day 62 - Watered 48oz. pH 6.5 water only..no nutes, no CalMag. Trimmed a few crispy leaves.
Day 63 - Watered 48oz. pH 6.5 water only..no nutes, no CalMag. Trimmed a few crispy leaves.
Day 64 - Start of week 10. Watered 32oz. pH 6.5 water only..no nutes, no CalMag. I think this is ready for harvest or really close. Seeing more amber trichomes. :) The leaves are looking worse I think but the buds have fattened up a bit. Hardly any sugar leaves are surviving. I can give the crispy looking ones a light tug and they usually just fall off. I've trimmed away a lot of sick fan leaves also.
Day 65 - Watered 32oz. pH 6.5 water only..no nutes, no CalMag. Plant still looks bad because of crispy leaves but buds have fattened up significantly. They look really good. Will take more pictures tomorrow and more than likely, I'll chop it down for harvest. I guess I jumped the gun on setting this week's entry to "Flowering". Does anyone know how to change it to "Harvest"? I've sent message to site admins/mods but no answer.
Day 66 - Harvest Day. Pulled plant out of tent and trimmed all fan leaves that were left. Buds are super sticky. Pulled light from tent to prepare for drying. I strung twine from the corner poles to make an 'X' in center of tent to hang buds from. I cut main branches to 5 manageable "bunches" and hung from string. Closed up tent with no light but heater and 6" fan running. Also have main vent fan running. Now we wait.
Many, many, many thanks to GreenMachine for all the encouragement and advice. I owe ya Dude.. Your a gentleman and a scholar.
Day 67 - 3/30/20: First day of drying in tent. Humidity a little low 35-40% so I turned on humidifier to get a little closer to 50%. Temperatures in tent are mid 70s during day and mid 60s at night.
Day 68 - 3/31/20: Drying in tent. Humidifier keeping humidity in 45=50% range, temps are ~71* in daytime and ~63* at night.
Day 69 - 4/01/20: Drying in tent. Humidity ~50%, temps ~63-71*. Flash pictures really show the frosty looking buds!
Day 72 - 4/04/20: Buds appeared very dry and small stems would break instead of just bend. I decided to trim and jar the buds. Since I have no idea how to do this, I just tried to make the buds look like what I've bought before. I trimmed all the sugar leaf stems I could find and the trim/cut off any leafs that were sticking out conspicuously from the bud...sort of like a haircut I suppose. I discarded any brown or damaged leaves from whatever problem I had (I noticed that these leaves smelled "funny"). In the end, I have a small bag of sugar leaves left over and will either smush these for concentrate or cook them into butter. There will be a few stems in the jars as I left a couple of clusters together because they looked so perfect. I jarred the buds with Boveda packs and I'll monitor the humidity and burp jars daily for awhile. I'm pretty happy with this despite the issues I had and will try again. I didn't know what to expect in terms of yield but almost 4 ounces from one plant is pretty darn good I think.
