i have an 8$ ph meter that works great.... no its not digital so you cant see EXACTLY what the ph is.. still beats the shit out of spending a $$$ i'm not even about to read again....
From what i understand in the LED game is no good specifically for the price and you aren't sure of what you're getting unless you spend 1000$+ which.... if you have the money, more power to you i guess.. but if anything goes wrong you have to replace the whole thing. you cant just go to home depot and get your fix asap or a whole new set up in only a couple days. unless you built it from scratch and have that kind of time.
even if i had the money i would opt for the same to better quality MH/HPS set up at half the cost for those last 2 reasons alone.
MY opinion is do what you FEEL.. There's so many ways to grow and so many opinions and different situations.
read your face off, do you best to gather the info you are looking for and follow your gut!
i was about to upgrade to LED but.... after reading and reading and reading...
i went with 4 150w hps ballasts and they have lasted me for many years and the bulbs i can just go to home depot or other hardware store to get... the plug n play set ups their self were only 80$ a piece.. on amazon..
and do a very very satisfying job i might add. so i have 600w "spread out" and i only spent 340$
TO ME... That dominates the 800+ dollars i was going to spend on ONE LED 600w LIGHT. It doesn't even make sense to me unless you have a warehouse and a HUGE electric bill.
to perpetual grow you have to do a bit of math yourself.
how long are you going to veg? how long do your ladies flower?
attempt to have another plant to the height you want it and beginning to flower around the half way point or sooner of your currently flowering plant.
This is just how i feel! good luck on your first grow! write down everything!
today starts my first grow with fem seeds!
