Vertical Flooded Tube Dual 600w - Hash Plant

Nice setup. How do you get inside to do any maintenance though?

Final weight was 1068g. Not what I wanted but not terrible. Comes out to 0.89grams/watt which ain't bad but I've seen better. The bottom row (Golden Goat) alone made up over half the weight at 19oz, however, I believe it was a result of vegging longer than the Hash Plants. The root masses of the Hash Plants never quite matched the GG, which had lush root systems and had been vegged for 2 weeks. I initially said I thought it'd be best to flower quickly because of root sizes and stretch, but I believe that for the next grow I will veg them a little longer, then use bushmaster to control the stretch. This should allow me to control the canopy with much more precision and will allow the root system to develop a little more. I'm thinking 10-14 days veg should be just about right. Had I done that, I could have hit 57oz or more, if you figure it by multiplying the bottom row by 3. Also, I think it would be a good idea to add another level. The reason I say this is that there was some light 'spillage' at the top and bottom. Had I had 4 levels I believe I could have pulled close to 5lbs max, and close to 6.5 if I had 5 levels, still using 2 x 600w bulbs. This is based on yield per square foot calculations. I believe anywhere up to about 3 oz per sq ft of canopy is possible, but this grow came out to 1.7oz per sq ft. Something to note, however is that the Golden Goat came out to about 2.7oz per sq ft, but the Hash Plant killed the average. Take the Heath Robinson flooded tube. His initial canopy space was about 50 sq ft and he got 46oz which means he obviously acheived a lower yield per sq ft at about .92oz per sq ft but he maximized his light usage by creating a larger area of canopy. If I were to add 2 levels, my yield per sq ft would probably drop a little because it would mean the plants would average a further distance from the bulb, but the additional canopy space should over compensate. Finding the right balance is the key.

send me some in the mail lol.. How much did it cost you to set up this system? and does it have any smell to it?

Haha... I'm not gonna respond to that first part. It cost me about 16-1800 when it was all said and done. It started to smell amazing towards the last 2 weeks. I tried putting one of those carbon filters that looks like an air intake for a car, but it didn't do much. Maybe should have just used Ona Gel.

It was tight, but I could slide underneath and sit up between the plants and the tube. Like i said, it was a squeeze. A lot of the work I could do from the back though.

any pic of the dry buds?

PVC is FUN! Been working on this one since last year, Haven't had time to do anything with it.....until now, just about ready to do my first run.

How do you control the water level in each section?

Shouldn't you have drilled the holes for the pots on an angle so the plants don't grow straight up?

i am building something similar to this i love your design what are those that you use to hold up the pipes

Hey sorry, i got in a major hurry to leave. I'm in New Zealand now, shredding it up, but forgot to take pics before I got rid of it.

Sick, buddy! I love the pvc support idea. I might use your design on my next grow when I get back. I built a 3/4" pvc frame for mine that my roommate is now taking care of while I'm gone until October, but yours looks much simpler.

I used these 3" rubber pvc endcaps cut in half so you can take them out as needed. You gotta play with them to find the level that suits your needs. But the good thing is, once the roots have developed, there's almost no need for them except for in the event of a power outage. But for that I bought a surge protector with a battery that will last a few hours running the pump. The roots themselves will also cause a little damming of the water as well, so it works out well where you can kinda just run the pump. With the battery pack, the only thing you have to watch for is pump failure.

Shouldn't you have drilled the holes for the pots on an angle so the plants don't grow straight up?

I thought that after I built it, but then towards the end the water gets pretty close to spilling over so had the holes been on an angle, it would have spilled a lot.

I used 2x2 lumber with 4" L brackets for support, but look at grow4flow's design in the pic, I like it better. Looks much simpler.

that is my frame going to add some supports also when i put in the 4" soil pipes i am using heath's setup as an inspiration to mine.
