Re: The Great Substrate Debate--Wood Lovers Paralysis [Re: djbabyjesus]

From:  "Effect of red light on Pi uptake and accumulation a,b, Visualization (a) and quantification (b) of ³³P-labelled Pi uptake by ten-day-old Col-0 seedlings. In a, images of Pi uptake by the seedlings exposed to white light (WL), red light (RL), far-red light (FRL), blue light (BL) or darkness (D) for 24 h were shown in the upper portion, whereas images of Pi uptake by the seedlings whose roots (WL/D, RL/D, FRL/D and BL/D) or shoots (D/WL, D/RL, D/FRL and D/BL) were covered with aluminium foil during light exposure are shown in the middle and lower portions, respectively. n = 4 biologically independent samples. c,d, Visualization (c) and quantification (d) of uptake of ³³P-labelled Pi by ten-day-old Col-0 and phyB mutant (phyB-9) seedlings exposed to white or red light for 24 h. n = 4 biologically independent samples. e,f, Visualization (e) and quantification (f) of uptake of ³³P-labelled Pi by ten-day-old seedlings of graft chimaeras generated with phyB-9 scions and Col-0 (wild-type) rootstocks (P/C), Col-0 (wild-type) scions and phyB-9 rootstocks (C/P), Col-0 (wild-type) scions and Col-0 (wild-type) rootstocks (C/C) and phyB-9 scions and phyB-9 rootstocks (P/P). n = 3 biologically independent samples. In b, d and f, the same letters above each bar indicate that means did not differ significantly at the 0.05 level in Tukey’s multiple comparison test. g, Pi content of Col-0 seedlings grown under white light for eight days (WL) or under white light for four days and subsequently under red light (WL → RL), far-red light (WL → FRL), blue light (WL → BL) or in the dark (WL → D) for four days. n = 5 biologically independent samples. **P < 0.01 and *P < 0.05 indicate significant differences compared with white-light-grown seedlings in a two-tailed Student’s t-test."


In the study, it shows a red light to increase the phosphorous uptake and a blue light to reduce it.






In Effects of Blue and Red Light On Growth And Nitrate Metabolism In Pakchoi, they show "the nitrate reductase (NR) activity, nitrite reductase (NiR) activity, glutamine synthetase (GS) activity and glutamate synthase (GOGAT) activity were highest under blue light. Further, the expression levels of NR, NiR and GS genes were significantly higher under blue light. Under continuous illumination, the auxin content (IAA) in pakchoi leaves was highest under blue light, whereas the abscisic acid (ABA) content was highest under red light. In contrast, there was no significant effect for gibberellin (GA) under any type of light treatment."


Using only blue light for wood lovers should effect the architecture of the mushroom and its ability to uptake phosphorous. This should result in lowered WLP symptoms in the finished fruits.

Usually people on the advanced mycology forum recommend people post here instead, but I'm going to say this probably belongs in the advanced mycology section.  It'll get more views here though!

Very interesting!

Thank you! I thought about that too. It's sort advanced cultivation, but imo all of mycology is advanced if you want to do it right.:wink:...I chose this section because I figured it would take longer to perform these experiments on my own than if I teamed up with the wood lover growers community in the cultivation section. While it seems advanced, in practice the methods are as easy as watering marijuana plants, adjusting nutrients, controlling lighting and the use of rooting hormones. I feel/hope the methods and ideas discussed are within the spirit of the cultivation section. If correct, it could be a game changer for wood lover growing in general.
