I was nervous in years past and eventually went from soil to coco because I was too afraid to take the full plunge into hydro. But now that I've started, you're not kidding. Little more money/effort/planning up front, but then its sit back and relax lol
Lil tip for you that will save you like 70% on the nutes bill.
Use the manufacturers recommendations to get the ratios but the ppm meter tells you how strong to make the feed.
If it goes up it's too strong so add more water.
If it goes down it's not strong enough so add more nutes.
Start at 200ppm and don't up it till the ppm starts to drop about 2 weeks later.
Then it's roughly an extra 100ppm per week of veg and levels off when you go into bloom.
If you keep the ppm steady or just dropping slightly then not only are you not wasting any nutes but you get an easy week without having to adjust the ph. Does save you literally 3 quarters on the nutes bill and you'll never get any problems whatsoever
I completely change out the water every 10 days or so PH'ed and nutes. I am on well water so it comes out the tap at 6.8 or so. 5 gallons per tub and still on the same bottles for the grow so in my opinion its pretty reasonable price wise.
