psi is pounds per square inch or a basic measurement for pressure. Andrew
They do sell low pressure emitters for such systems but I can't remember who they were.
Ron Also the misters I have are 4psi and I need to run 4 of them. Andrew
The bigger pump you use the higher psi you will get but how big of one that will be adequate for your system I'm not sure. I slept threw algebra class.
ron ... i have something for Andrew on building pressure.
Use power spray or high powered jet pump.
i once used a 3/4hp jet pump for a 18 nozzle aeroponic chamber,
remember to use brass or stainless pump. if you use a cast iron pump, then prepare to have extra money next year for some supplies.

Ron,
I'm setting up an indoor hydroponics system and wanted to know how to manually cross pollinate tomato or other plants since the bees can't do their job indoors? Also, do you need to grow male/female plants for this?
Thanks Tim
For tomatoes if you gently flip the flower it will pollinate it. because tomatoes are hermaphrodites the inside stem in the flower being male and out side being female. zucchini and others use a cotton swab and go around to the different flowers. Andrew
ron i have built your 11 bot sys i like it real fine i have added on i have 40 boy now i have peppers planted and they look real fine but i have a little tip burn what should i do about this am i using to much nutrients are what claude
Yes I would cut back a little.
ron, whats an accepitable level or flow rate for co2 in cubic cent. i have an equation but its in cubic feet and my gear is in cc thanks, tim
Tim,
There are 28,317 cubic centimeters in a cubic foot.

Hello Ron! I've 2 ?'s 4 ya! First, is it a no-no to leave the root ball of a deceased plant in my ebb/flow system? I'd take it out, but I've got another healthy plant in the same rockwool cube. I'm using cubes in grow-rocks. Also, do male cannibis plants grow clusters of pollen sacs, or just two 'balls'? I thank ya kindly!
Yes The root ball will slowly turn into organic mater
and add some particles to your tank.
clusters and a lot of them.
What are some commonly available media substrates that you would recommend? (ie where can I easily get grow rocks?) sharkdude1@yahoo.com
lava rocks, perlite, wood chips, gravel.
hi ron
regarding CO2 enrichment
know of any home remedy where i can enrich my growing area with CO2 ?
burn something ?

CO2 is one of the
by-products of combustion. Any hydrocarbon fuel
can be burned to produce CO2, except for those
containing sulfur dioxide and ethylene which can
be harmful to plants.
You can use dry ice. Two pounds of dry ice will
raise the CO2 level in a 10-by-10 grow room to
about 2000 ppm for 24 hours.
Fermentations is another way to add CO2 to small
grow rooms if you can handle the smell. Use a
one gallon plastic milk jug and mix one cup of
sugar and a packet of brewers yeast with about
three quarts of warm water. This concoction is
changed one to four times daily as needed. Half
of the solution is poured out, then 1 1/2 quarts
of water and another cup of sugar are added. Add
more yeast if needed.
SEED SPROUTING
Here's a site that gives good tips on seed sprouting.

so ron, i wrote a while back concerning the a light I had purchased. It was a 1000 watt sunsytstem (HPS). For three generations since i have bought the light, i have yet to get a decent harvest. the flowers and leaves yellow and die quickly, and about 3/4 of my garden dies before it gets to harvest time. I know that growing plants cannot be this difficult. So, here's the question:
Have you ever heard of a ballast or the bulb itself being faulty (before 12 months for the bulb), but still working and giving out light?
No I have not. I don't think it is your light spectrum. I would buy a light meter to make sure at least they are getting enough lumens.
My bulb compared with a friends regular HPS bulb does appear to be more yellow to red in spectrum. If it's the sunagro bulb, shouldn't it appear to be less yellow or red?
I have tried all brands and have noticed that different brands do put out different shades of light. MH is always white but HPS are different colors.
Hello Ron, This is the most excellent site i seen. I need your advice of what you use for soil? i happen to see people mention about grorocks and lavarocks? i am new at this hydroponics and need to know what soil you guys use for hydroponics. i am guess it is not regular soil? Thanks a bunch. peter_ha@excite.com
Soil! What is soil? That must be the crap I wash off when I buy bedding plants from the store.
Hello Ron!!
Why are my plants yellowing towards the end of the flowering cycle? I'm using an all-round nutrient pre-mixed solution, is this the best thing to do? Also, while you're there, which hydroponics system of growing do you think is the most energy efficient? Thank you, from Peaches.
I would increase the strength of your solution. The big lower fan leaves do turn yellow in the flowering stage because they aren't needed anymore and should be removed.
Kitty litter as hydroponic grow media?
I have been reading on various pond sites that some people use non odorous and non clumping kitty litter as media in slotted pots to grow various water plants. The argument is that the cheap stuff is just plain clay. There seems to be some agreement that the clay may bind phosphorous and thus limit undesirable algae growth. They also recommend adding potassium so that the plants may better utilize the phosphorus directly (potassium as a cofactor). What are your thoughts on these topics?
You have sparked my curiosity and I will pick up a bag and give it a try and post the results.
Hi from Australia. Have just set up yet another Hydro room. Every thing seems to be going well after a couple of weeks other than a couple of the plants have white dots ( spec's ) on the leaves. Started out on just the one and seems to have moved on to 2 other plants. Other then this everything looks healthy Should I worry ??
Maybe. I would watch to see if they have any negative affects on you plants.
DEAR RON I AM IN TEXAS AND HAVE A HYDROPONIC TOMATO OPERATION OF ABOUT 14,000 FEET I HAVE HAD A FEW PROBLEMS THIS YEAR AND I WAS WANTING SOME INFO ABOUT GROWING BELL PEPPERS THE IDEAL CONDITIONS AND OTHER FACTS TO GROWING THESE PEPPERS I WOULD LIKE SOME HELPFUL INFO MIKE_TOMATO@YAHOO.COM
Nor, Bobcat sez good morning. What's happening brother?
Good morning.
Dear Ron, (Ha! feels like i'm writing to an agony uncle, no offence mate. :o) Does it matter if light gets to the roots? If so what's the best way to prevent this? Thanks your site kicks! easily the most informative, truly inspiring. Rich.
I don't think so as long as they are wet.
Do you know the desired ph levels for the growing solution of marijuana?
For the majority of any type of plant between 5.5 and 6.5 with 6.0 being the best.
I'm growing tomatoes and lettuce and using the Miracle Gro, Epsom salt, and calcium chloride mix but can't find the calcium chloride. Anyone have a source? I was hoping that there was something I could get locally. Any ideas? Thanks.
local is relative. If you live on the moon then you might have a problem. You have to get out the phone book and start calling nurseries, fertilizer supply stores, farm supplies, ect.
Re: CALCIUM CHLORIDE
Go to http://www.dow.com
Click on "Products and Services and follow the links that come up. There is a list of local distributors there.
Thank You
Hey Ron!!
I found a website for hydroponics that's pushing coco fiber. They say that mixing it 50/50 with grorocks gives an ideal growing media, and reduces the cost. Oddly enough, the coco fiber is sold in bricks. The bricks cost about 30 bucks for 25 of them, but after you uncompress them they expand about 20 times the volume.
Have you heard this or if so, have you ever tried it? I'll try to find the website again and give everyone the URL.
I am using a commercial nutrition for my ebb and flow
system. I have heard that tomatoes need quite a bit of
magnesium and since I am growing tomatoes I don't know
whether I should add some epsom salts or not to up the
magnesium.
Lee
My commercial bag of hydro fertilizer says to add some.
I have a small ebb and flow system. I am trying for the first time 3 different tomato plants. How is the best way to pollinate the blossoms? George
Flick the stem with your finger right where the flowers are but don't brake them off.
