@MindFlowers68, Thx :)

@@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.

@Qutro, I wish you the best ! thanks

@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!

@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.

@1_Plant_Wonder, Thanks ! :pray:

@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.

@Qutro, Thanks ! yes i do it for fun and to see how the plant react to the extented PAR because i read a lot of contradictious trials and comments about the UV and Far Red. I got these 3 pucks for the price of one, so... ;) The next run will be different based on my observations. I refeer to Dr. Bruce Bugbee which confirms other studies i have read. At this stage, as he said, i confirm that the Far red may be usefull during veg for elongation shaping, but nothing to do with floral induction.

@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 :relieved:
