New grow tent DP90 (90x60x98 cms) New 4000K projector 20w Philips Ledinaire (2400 lm, 120 lm/W, Symmetrical wide beam 110Β° x 110Β°). Got it for free from my workshop. Used to complete the PPFD on both sides. Pros : Very bright and great to penetrate the canopy. Small wattage. Cons : They are hot and need an active cooler. (note: all the leds works. if you see some led off, it's due to the photo sensor with this type of floodlight) Feeding: Terra aquatica NovaMax Bloom NPK 4-8-7 (just enought. No need of PK booster) ATA XL stimulator (only the last 2 days of the week when the tank is close to be empty) Irrigation x4 per day. EC 1.4 in - EC 1.2 out - PH 6.0 The run to waste is perfect. Zero salt accumulation and the plants are eating very well. LEDs: PPFD 700-800 on both sides, 950 in the middle, 1350 at the highest point. No heat issue. I got a Vapor Pressure Drop issue with Calcium/Boron deficiency on some leaves. But the flowering and overall grow has not been stunted. I fix it by increasing the moisture to 47-50%. Note that is a test session, to see how it performs with the pucks addons/wavelenght in a small area. The next run will be different by experimenting far red in veg, uva during the stretch, and far red and uva at late stage. I will do the things by following the Dr. Bruce Bugbee's notes, with more elongation to fill the area in veg for a "candella/lolipop" style without adding any extra veg week, UVA during the stretch to have smaller inter-nodes distance, and the last 3 or 4 weeks all the stuff to promote the pigments and terpenes, and only Red flower during the budding phase, and late phase of course..

Beautiful grow experiment you got there!πŸ‘πŸ½ Super healthy plants for that stage in flower πŸ˜‰ Following up 🌱

@roxgreen, that's some great info you provided me with my friend! Some food for thought no doubt, Thank you for the detailed message, I'll definitely look at the photos you posted! Yeah for me the challenge is the vertical hight, as I also use run to waste technique, and I do it the old fashion way with a hole underneath for collecting the water manually πŸ˜… so the 140cm hight is beraly enough for me, and I also applied the exhaust fan and filter outside my tent, So I'll definitely like to see smart (!) Small setups to help me manage things better, Thanks again for the info!✌️🏽🌱

@1_Plant_Wonder, 40x40 is very small, if you start from clone it is possible but too hard from seed and irrevelant. i started with a DP60 (dark propagator from Secret Jardin in Europe), very cute box and setup but here again, from seed, it's really hard, or maybe with only 1 indica plant. That's why i switch to a 90x60x98 DP90 Secret Jardin (https://www.secretjardin.com/product/dark-propagator-90/). wider, still small tent, and yes... it's the minimum requirement for flowering. Yes i use an extractor and filter. google DF16E150 for the extractor, and DF16F150 for the filter. You can mount them outside in push mode like i did in the DP60. i have changed to pull mode in the DP90 because there is room for that. In the DP90 you can put a bigger filter if you want, it works nice and 24v, small footprint too. Check the new pics i posted for you about it. I use both for the DP60 & DP90. A little more expensive than other brand and classic design but the integration with the secret jardin tent system is great (https://www.secretjardin.com/ducting-flange-connectors/) I really like their flange system because you can do your hole with the tools they provide, where you want and as much as you want, even for the cable & irrigation management. I grow for many years now in 120x120 (4x4) big tent, 3x3... but i definitly switch to a smaller setup. Note: for the DP60, i customized it a bit by adding a water deep tray for my run to waste system. it add 18 cms in depth, require a DIY table cut out and some screws. You can watch the trick from the photos.

@roxgreen, love the smart mini setup! Wanna do something like that one day soon, I do have a 40x40x140 but I wanna do something wider and vertically shorter... Do you use an exhaust fan and carbon filter? If so how small is it? πŸ˜‰ Thanks in advance!✌️🏽🌱

@roxgreen, I see what you mean. For me also vpd and ppfd are the key factors. Will follow your journey. Have a nice holiday mate!

@Qutro, Thanks ! There are so many controversial studies and reports about the Far Red. yes, no problem with the Red, but with far red it is another story. This is a wavelenght that we must use very carrefully. and if we use the far red too early in flowering, it can affect the overall yields. That's why i plan to use the far red only at the late phase, when the buds are etablished, after the budding phase so. Cannabis does not react like others crops. That said, i only experiment some aspects that i find interesting. Also, the far red at the end of the days after lights off could promote a better late phase. I look for pigment, terpenes and overall quality, and... of course a good yield but it is not my goal to have more weight, just normal and i m fine. I think PPFD, vapor pressure and optimized nutrients uptake by feeding with the lower EC are the keys.

Similar situatio to yours: Due to a time crunch I have to start 3 plants for 2 weeks in a propagator tent while my current cycle finishes. They will be hand watered in rockwool under an old 200w blurple light. Then they will transfer to the bigger tent with drip hydroton for a few days of veg under 300w COB before flipping to 12/12. I have to harvest at 9 weeks in order to dry and process before moving day... Can you give me an indication of harvest weight per plant so I can plan accordingly?

@Lemonhazelover, Thanks guy :) i make this challenge to grow in a propagator tent. I don't need more and it fix a lot of indoor issues. Only the stretch phase is critical but that's the rule 😌

Why are the big leafs still there? Interested in leafs or buds? When you like big buds, then the buds need the light. 😎 Make her naked.

@@FraFra__frankenstoner_Two_days_in_a_day, Hi ! because a plant need active leaf for photosynthesys even at very late stage. There are enought PPFD here. Photosynthesis, and vapor pressure are the key. Defoliation come here to de-stock the nutrient a bit, during the ripping phase. the photons conversion need power, and it comes from the leaf, not the fruit.

Now is a good time, to defoliate the plants.

roxgreencommenteda year ago
hi ! i never defoliate late in flowering. It breaks photosynthesis and force the plant to make new leaf. I will just do a bottom defoliation the last week to help the ripping phase.
FraFra__frankenstoner_Two_days_in_a_day
At least one plant can be defoliated. About two or three weeks to harvest.😏
FraFra__frankenstoner_Two_days_in_a_day
The small lamps on the sides, should go to the bottom of the tent, and shine up to the plants. This way, the buds get more light.πŸ˜‰
