So I am sitting on a 33 acre lake filled with fish. I am close enough to just pump water out of it. Could I just use this for my plants? Would I even need to add anything or just run straight lake water? Isn't this basically aquaponics?

I have noticed that the plants under the cobs are more consistent in size and mass. While the plants under the QB and CMH are more random. This is likely attributed to the fact i only have 1 of each of those lights and they are not in a tent. I would like to make a full table of QBs. Anyone...

those are some nice looking plants.

Current grow. So i have 36 plants going right now, they are all exactly the same variety and are in the same growing medium, I have noticed some things, thought this might a good spot to mention it. The setup as follows: 2 tables at 3x12 feet each table has 3 light fixtures on it for a total...

How do you like the UV tubes? I bought 4 of them once and never took them out of the box. i haven't been able to find a practical way of adding them to my lighting setup

So I am trying another large run of plants. This time, I decided to do a hybrid method of growing. I have no idea if this will work, or if it will be a total disaster. Any thoughts on this would be great. I am growing in 11 L bato buckets, i drop a few inches of clay pebbles in the bottom...

LOL! added a banana! I don't think that is going to help much. I don't think you will get enough gas from that banana to do much.

that's an option. I am curious of the the PPM of melted snow. can you get a reading on that for us? Then I wonder if its the same everywhere or if it is lower or higher depending on geographical location.

if you guys are interested in an RO system for you grow area, this is a pretty good option, it is a little more expensive then a under sink one. https://www.freshwatersystems.com/p-6853-axeon-hf5-4040-2500-gpd-ro-membrane-element.aspx then you need a housing for it. They are about $100. you...

I have really hard water, it comes in at .6 EC. Its also really alkaline, it runs in the upper 9s. I would like to build a practical RO system. I am less concerned about the PH of the water. That usually drops like a stone when i add my nutrients to the water. What i have started with is a...

Try using a larger volume of water when mixing.

Question, how are you mixing your nutrients into your reservoir? are you mixing them together then adding them to your reservoir, or do you measure them out individually and add them? This matters, if you mix different nutrients together before you put them in your reservoir they will cancel...

HA! We have spent a lot on lettuce growth. But each head i grow the cost drops

Or has anyone used FoxFarm Ocean Forest Potting Soil? Might that be an option?

I need some suggestions. I have 11 liter bato buckets, I ran them with 2 to 3 inches of clay pebbles in the bottom and the rest filled with coco. I decided to give running 6x6x6 rockwool cubes a try, i am going to stick them in the bato buckets. I will probably keep the 2 to 3 inches of...

Yellow Leaves... So I have 18 plants, all identical, 6 under 3500k bridelux strips, 6 under a CMH and 6 under a mix of 3000k and 4000k vero 29s. The 6 under the bridgelux strips have greenish yellow leaves. The ones under the other lights both have the same normal green leaves. I find this...

I used low end 6000k 22w cheap integrated led strips. They worked well were cheap. how big of a foot print are you running?

i like the idea of filling it out with grow cubes. maybe throw some clay balls on top so the rock wool doesn't get all gross. thanks

im going to try the 6x6x6 cubes in a 11 liter bato bucket with coco filling out the space left over.

aquaponics is a bit more then i want to do, lets say you had coco, soil, a big 8x8x8 rockwool cube and perilite. I will not talk clay balls because i DTW. what would you think would do the best for tomatoes? these are all going to be in a 11 liter bato bucket, mostly because that is what i...
