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...

nice set up, how many floods per light cycle? drain as soon as tub/bucket is full or hold for a few minutes? so your tub/bucket/or NFT has direct light entering the container?

nice, that's reassuring to know. any direct light getting to the roots much like a net pot half filled with medium so sides are exposed to the insides of the bucket or an exposed service/ fill hole?

ph seems pretty stable as i ph once a week at 5.5, climb to 6.2 or so then ph back down. so your personal experience with roots exposed was detrimental?

hey all, grown in soil once before many moons ago, currently in my first hydro flood and drain set up and every thing is going ok. set up is as follows for seedlings: - light cycle 19/5 - seeds/clones in rockwool - 100 x 50 pvc rectangle with 38mm holes drilled for rockwool * once rooted 2...
