Plants are looking happy this week. Bud sites are frosting up, and the plants are getting thirstier.
After last weeks burned tips I decided to flush and measure pH and ppm. pH was at 6.2-6.3 pH for all 4 plants. TDS was high, but the plants seem fine. Whatever issue there was is gone.
Fed them again with 5 tbsp of Power Bloom and maybe 10 tbsp of worm castings each. Might feed like this once more in 2 weeks if they seem to want it. 👍
Hey all,
I mixed together 40L of Coco and 10L of worm castings, and left it sitting with a lid. Sure enough, it has some mold growing on the top. Can I still use this medium or should I just throw it out? (Not broke, but cheap!)
Thanks
Venting into large basement area separate from lung room. Averaging 65% RH in tent. How can I vent my grow tent out a century old red brick home's original basement windows discretely? Or, can I vent into an old (capped) chimney without removing the cap? Lung room is 6x10.
Hi mate, if its a proper cap then it should allow air through. Otherwise it will eventually fill the house. Condensation would be another issue as the air will cool by the time it gets up top. Good idea to have a reservoir to catch any water running down inside of flue pipe. If the water is acidic it may attack the flexible flue already in there and cause a riddor reportable event (if in use by any heating appliance) which will mean the hse and any other official they want to find blame as to why a gas flue deteriorated will be paying you a visit. Good luck and happy growing
Does total disolved solids (TDS) matter when growing in coco, worm castings, and organic dry ammendments? Am I at risk of a build up of salts? I have seen 2700 ppm in my current grow, but are these simply not salts and therefore OK? Plants look good happy. TY
I am using 20% worm castings and only organic nutrients in this grow which has provided a simple feeding process based on top dressing only. I do add CalMag every water to ensure the coco is not draining all available calcium and magnesium.
I have taken readings throughout the grow, and have seen from 1800 to 7000 ppm, mostly around 3000+ ppm readings.
I've had about 5 rusty leaves and the same amount of leaves with burned tips, but I think this was deficiency, not overfeeding. 13 weeks in, these plants are thriving.
While I agree TDS matters, watering to 20% run-off and ensuring your TDS is at 700 in veg or 1500 in flower while growing with this medium combination is not necessary, and may leave the plants hungry.
Will my yield match a hydro grow? Time will tell. I am sure by dialing in environmental factors and more accurately feeding we could come close, albeit not as quickly.
