aloha, i do apologize for my ignorance before, i learned all i needed after posting that last question, but now i have just one problem. i have designed and am building a 22 plant system (i need to grow a lot of "product" quick) and i am not sure what size pump to use. if you could help me i would appreciate it. my email is s191641@hotmail.com.

About 80 to 150 GPH would work.

Hi, I have one more question concerning my plants (growing in 3" by 3" Rockwool). They have been growing from seed for a little over two weeks now and they have not really grown vertically at all. Every new leaf set sprouts RIGHT on top of the old one, and the plants themselves have stayed at about 2.75" for almost a week. The stems on the healthier plants have thickened and seem very fit. Is this normal, will their stems eventually elongate? I want them to reach a height of 8-10". Remember that they are in 1.5" of water (aerated with an airstone) all the time, in a 1' deep by 21" wide space, and look healthy but a little wilted. This is my first batch of little guys so I don't know what to expect. :-)

I would say to much watering. Most plants need a dry period between waterings for healthy growth.

can you give me a general idea on how much baking yeast to use per volume of water for a grow room (closet 2' x 2' 6' high) for co2 enrichment. How often should I add new baking yeast? I've got a 20 oz. co2 tank for my paintball gun. Would it be a better idea to find a valve that would fit this, and barely open the valve to release co2?

Not sure about the yeast and yes the co2 tank would be better. Even doing a lot of heavy breathing in your room would help.

We have some raw cypress knees cut from the swamp. We'd like to find out how to remove the bark and clean them up so they look like the ones you can buy? Can you tell us how to get the bark off and shine them up?

You boil them in a big pot of water and linseed oil and the bark will fall off and they turn a pinkish color.

You've probably had this question a hundred times. I am starting an ebb and flow system and I would like to know at what intervals to flood and for how long.
Thanks

Flood about every 30 minutes and let it drain immediately.

Would anyone know if tap water at about 130ppm could be used with general hydroponics (micro, grow, bloom) without harming my plants? Just wondering if 130ppm is considered high for tap water too? Thanx. Mark

130 is about right for tap water. My well water is 250 PPM. If your water has a lot of chlorine you can let it sit in a open bucket for 24 hours to let it evaporate before use.

hey ron, george from crescent city fl. have a couple of tomatillo plants in the hydro greenhouse. do i need to hand pollinate (electric toothbrush) them as regular tomatoes? have searched the net but came up empty concerning the subject. ps, you sure get some strange questions on your site. can understand the quote " take another toke". good growings, george

My guess is yes. What are tomatillo plants.

The vertical space in my grow room is slightly limited. I've read when my plants get closer than 20" to the bulbs they may get burnt, is this correct? Is there any way I can screen the light out when the plants start getting too close? Perhaps use a metal screen or some type of light barrier? Thank you

A tempered piece of glass between your plants and light is the only practical way I can think of.

Ok I hear a lot about using HPS and MH lamps for indoor gardening, but what about Mercury Vapor?

The mercury vapor lamps produce only 60 lumens-per-watt and does not fulfill the requirement light spectrum thus making it a pour light source for horticulture. Not only it is an expensive to operate, but it produces most color in areas that are not helpful to plant growth.

I found a 125W MV lamp at Wal-Mart for 35 dollars. I think it puts out about 6000 lumens (I may be off on that)

Also ron do you think that 125w MV lamp, a 100W MH lamp, 2 60W grow lamps, and 135W fluorescent tube is enough for 10 plants?

no

400W HPS lights are so expensive so I tried to go a cheaper route buy using alot more lights.

I bought 2 - 400 W Metal Halide for 30 bucks apiece at a flea market that came out of a factory. All I had to buy is new bulbs. They are out their. You can go into almost any large building or factory and look up and you will see MH lights. When those factories go out of business somebody buys and resells those lights for almost nothing. Resell shops may be a good place to look for cheep lighting.

thanks

I am looking for a manufacturer who produces a 1/2 inch rubber (bulkhead) grommet seal to insert a plastic barb fitting into a plastic water container. I am trying to make a dutch bucket hydroponic system and need this grommet for the nutrient flow lines. Larry

Try www.aquaticeco.com they have a good selections of bulkheads.

Will the 11 plant system pictured on this site allow enough root expansion for flowering plants up to 1.5M in height?

If you water the plants often enough then the roots don't need a lot of root space to mature to that size. So yes you can but I would put more space between the bottles if you grow them that big.

the timer i have does not have a ground inlet, but my pump does, is it okay to run the pump without a ground?

Yes But keep your hands out of the tank when you plug it in or out.

How Do you keep the water level in the Bottles of the 11 plant garden stable?

That is what the overflow pipe is for. You put the pipe at the height you want the water to rise. Don't forget to drill a hole at the top of the pipe to stop the siphoning effect.

Ron, I am growing in aerated water and my plants are doing well. I have noticed that algae is forming in the water itself. Will this cause problems for my plants? If so, can I get a common anti-algae agent that would normally be used in a fountain or pond or aquarium? Will that hurt my plants. Thanks

Put a lid on your container to keep the light from hitting the water, that's what causes algae. You can't grow hydroponicly without some algae. It means your water is healthy and has nutrients in it. I would start to worry if I didn't see some algae on my gardens. If it builds up to where it becomes a problem then change your water.

Ron, I must ask.... Could you please tell me why a 30-gal "reservoir" costs 70$ from hydro-dealers!? That's crazy stuff! More important, what makes grow-trays worth 100's They're the most expensive part of most setups. Yes, I've seen your 11-plant garden........you're a good man.

Because they are made to last longer and are rated food grade. Forget um. I have never used anything but Rubber Maid containers. They come in all sizes and are cheap. For my commercial gardens I use 50 gallon barrels that cost me 10 bucks apiece. 

You have to innovate like use rain gutters or pan-roof sections to grow in. I will be building some in the near future and posting pictures.

Ron why are you supposed to change your tank every two to three weeks seems with an air stone that water stays fresh & nice would there be a problem going 8 weeks don't notice any algae or anything thanks for the advice

I don't change mine unless my plants show signs of a problem. I think that two week thing is just another lie put out by the grow stores so you have to buy more nutrient solution from them.

I'm going to be building the 11 bottle system, what is a good starting point or the watering.. How many times per day, and how long on and off.. Thanks

Dave from Ottawa

Every half hour or so as long as the light is on. You don't need to water at night.

Hey Ron Ive exchanged words w/you B4. Advice helped, Thank You. Your 2ltr system rocks! These are cannibis plants... Ive been flowering for about 2.5 months now under HPS lighting. Everytime I think theyre done, I see more new white stigmas, over and over! Ive been air drying and smoking some, but they have that "green" taste to them. The high is alright I guess, but short. But they smell so skunky? When I touch them, and then smell my hands, they smell terrific! My lease is up in July, Im getting nervous! What is going on? Do I just need to be patient??? Any help would be great! thanx again,

HOOBNESS

What you have their is a sativa variety which will take longer to finish and some varieties never will if they aren't suited for indoor growing. Stick with the wide leaf indica varieties for indoor growing.

hello ron, im a new grower and have a system designed like the 11 plant system but on a smaller scale ive got 9 plants this may seem like a dumb question but what do you plant the plant into? (if you know what i mean), can you just put plastic plant pots with holes at the bottom into the upturned bottle lids? or does it have to be something specific, also what amount of water should i use? bearing in mind there's 9 plants, i thought maybe a gallon? sorry 4 the stupid questions ron, but like i said im new too all this and any advice would be greatly appreciated, cheers

I use 16 oz. plastic drinking cups that I burned holes into with a soldering iron. You could use the plant pots if they fit into the bottles. I think you will need more water than a gallon.

How necessary is it to have a co2 discharge in a small growing space (24" X 17" base, 6.5' high)? I have a strong fan forcing air out the room, and an inlet hole to allow air to pass in room. The grow room is a closet in my bedroom (for air source purposes).

co2 is the cheapest way to increase the rate and vigor to indoor plants but I wouldn't bother with small gardens like yours.
