or would the cut grass/ hay smell be from too much moisture?

hey, its autumn, nearing winter in my part of the world so room temps are about 12c - 20c (53.6f - 68f) no pictures

hey gang, - so my set up as follows 25/30l drum with metal clamp that holds an air tight seal. bottom is 4 side holes drilled which takes 4-6mm rubber top hat gourmets plumbed to a 800l/h air pump hooked up to an inkbird moisture controller and a vent hole plumbed in the lid. - aluminium fly...

hey thanks for the input. so the light schedule should be fine other than insufficient par/DLI, you thinking stretch? its a very small grow area where i start seeds/ clone/ light veg, as the grow height is not more than 2 foot( or less) which may include the led so at times canopy is a foot to...

so i've got a perpetual grow cycle going and my veg area is growing far too quick for the space. so going off the The Gas Lantern Routine wondering if anyone can see any problem with a 4hr on, 6hr off, 1hr on, 6hr off, 1hr on, 6hr off light schedule? flood and drain, perlite, 100w led dimmed to...

this calmag recipe sounds about right, should be able to use as a liquid concentrate to use just like a store bought version for quick use when needed if using magnesium sulfate as far as i understand can only be used as a ready to use solution eg 2 EC and under, cant be used as a liquid...

@Mont@n@ great thanks, that will keep me on the right track. seems to be a+b at 633ppm with micros at 5ppm which would be 10ppm at 1200-1300ppm of a+b?

great, thanks for the info. have found Bacillus thuringiensis in a power form, will see how it goes.

mosquito dunks wouldn't do any damage to nute solution/ plant if dropped into res/ tub housing roots? can only really find this as in australia https://envirosafeaustralia.com.au/wp-content/uploads/2019/11/Mosquito-drops-EnviroSafe-scaled.jpg i dont even have 5mm of room in my netpot, filled...

will give it a go but most of them are the tub latched onto the roots, which i figure their eating resulting in dead branches

does anyone know how much micro nutes to add with your a+b solution ? will be getting around to trying my own batch of npk as i can find hydro micro's in a all in one dry solution mix. so my question is if my a+b solution is say 200ppm are my micro's to be say 10ppm? so i up to 400ppm would my...

couple months old in veg, leaves are going faint green/ yellow, drying up along with branches. new ph'd res with h202 and a couple drops of bleach now and then. i have gnats which i think might be my problem, so as i'm in 3" netpot with 1"rockwool and supercourse perlite in a flood n drain i...

i would say you have way too much K locking out mag, your potassium sulphate has nearly twice the amount of k of MKP, considering your base nutes are also high in k i would ditch the potassium sulphate for a quick fix. ideally drop potassium sulphate maybe raise mag sulphate to 2.5-3g into a...

hey gang, just confirming are the ratio's above N P K or N P2o K2o ? e.g n p2o k2o of 5-5-5 really = 5-2.15-4.15 npk

fair call, i read up on calcium alternatives about a couple months ago doing research as i'm still learning too, what i took away from that is its not water soluble to a hydroponic standard as i thought i would take long time to dissolve in solution and most likely precipitate in the res so...

as far as my limited understanding goes, as soon as you have male parts you stop spraying STS as does take its toll on the plant and isn't need after male parts are formed

if your not running soil and your in hydro medium i would rethink Calcium Sulfate: 198g ( aka gypsum, poorly water soluble, soil use only ) Ammonium Sulfate: 43g Monocalcium Sulfate: 113g ( pretty sure poorly water soluble or has issues with hydro, you might need to do more research to be 100%...

Hey zem, yeah i do agree in general, i mainly just want to experiment really, that's why mixing up your own nutrients from scratch can be so useful , from seedling to early veg for root development and just for the transition period. currently using a store bought dry premix with micros at...

great thread have most water soluble horticultural/ elemental ferts to mix my own, currently only using as additives to my generic base nutes as i still need to source micros. my question is on Mono Ammonium Phosphate (map) for hydroponics eg not soil, now as far as my research goes 10%...

very cool, picture says it all! nice healthy plants other than a very tiny bit of algae, i now know mine will be fine healthy with my h2o2 version so will rule out light as any real problem. we run a similar set up except my netpots are hanging in the pvc so more room for air i figure. thanks...
