what's crack-a-lacin' ?
sure. i take the water from my hydro grow, put it in a couple of clean 5 gallon buckets with a good fitting lids, and hand water with that.
just make 100% sure the ph of the water you're gonna drop in dirt is higher... between 6 to 7 (6.5 being ideal). one wy to check where you need to be with ph & dirt : flush your plants with ph'd, fresh, water & check the ph of the water comming out the bottom of the planter.
i had been using nute'd tap on my plants (my tap is 7.4) for weeks (experiment), flushed, and the run off was about 6.2
if you're like me & don't own ph up (though i might score a small bottle) use fresh water to raise ph. remember always mix out your nute before ph'ing.
one thing i am gonna start doing, with regard to ph, is buy a pipette so i can measure exactly how much i need to put into 3.5 & 5 gallon buckets to get to where i need to be... with no waste.
i never feed my dirt girls nute'd water every day... every 3 to 4 days.
