I have reading a lot of confusion with hydroponics systems, nutrients,ect. It is often difficult to answer people's questions about hydroponics after a thread has been hijacked and false information has been posted.
I thought I would start a thread where people could ask hydroponics questions. No question is dumb and if it is well I'll tell you. I will also not tolerate any myths or false information.
I'm certainly no expert but I have been growing for years with hydroponics and have set-up and help manage grow operations in quite a few places. One of the best ways for me to continue to learn is to answer your questions so POST AWAY!!

Is a TDS meter really important if your changing out your nutes every 2 weeks?

what are the outside dimensions of a 900mm x 900mm ebb & flow tray in its stand ?
my tent is 990.6mm X 990.6MM X 2 meters LWH and i need to be sure the
900mm X 900mm tray will fit in its stand.
and on a side note if i know how big it is over all i will know how much black berry jam and molasses to order to really make my buds superdankelicious
LOL sorry NG had to toss a couple myths in there

Yes a TDS or EC meter is important to accurately determine nutrient levels in your reservoir. Changing nutes every two weeks reduces the risk of pathogens in your reservoir and also allows you to maintain proper levels of N/P/K and micronutrients. Top off with fresh Ph adjusted fresh water between changes. Never add nutes between changes doing so can cause problems with nutrient lockout.

They sell aluminum stands that fit right under the trays. I'm not sure if the 900mmx900mm measurement is inside or outside because there is a 1" lip that is used to support the trays in the stand. I would think with you tent measurements the trays with stands would fit fine, the tent walls are flexible too.

I'll take a blackberry jam and bud sandwich on wheat. I think they sell those toasted at Quizno's its actually called the "Superdankelicious"

Are the correct levels usually printed on the nute bottles or is there a standard number to go by? I've been a dirt-bag for too long and am new to the hydro.

Thanks for all your input.

There are usually recommended levels printed on the bottle. Sometimes they provide good guidelines but often they don't for all strains, growing conditions, ect. It's a better practice to find a brand you like and stick with it.
I would recommend using the manufacturer recommended levels at 1/4 strength and slowly upping them depending on plant tolerance and growth rates ect.

Any nute recommendations for a newbie.

Do you recommend additives such as bcuzz?

You will find a different opinion on which nutes are the "best" from every hydro grower. I prefer two part nutrient systems (easier to mix) and I personally have used "Ionic" nutrients for years with great results.

The only other additive I use is H202 35% 1.7mL/L. I have used humic acid additives and some bloom boosters before. I found that humic acid just left a residue in my reservoirs and bloom boosters caused burning early in flowering. If you want to use bloom boosters I would recommend their use only late in flowering (last 2 weeks). Don't use lots of additives however most are marketing scams and combining a lot of additives tends to cause more problems.

You can start now if you like, run 500 ppm and see how that works for you. They look good nice compact growth. What kind of nutes are you using?

Thank you for smoking!
