On my last grow I did 12 plants. Five of them turned out to be so infested with bananas (male flowers) at about half way through flowering that I pulled them from the room.

The remaining seven plants produced 2 lbs + 16 grams. This was with two 1000 watt HPS. This time Im growing 15 plants with three 1000 watt HPS so I expect a bit more per plant.

Four pounds is a pretty safe bet. I am hoping to get closer to six pounds. Anything over four pounds is a bonus, in my view.

damn 5 pounds with 15 plants and 3 g's of light.. how long you vegging?? these plants are gonna be huge

Ive been looking for someone useing a ebb and grow....ill be watching

I will veg for about three more weeks, less if need be. I will get them about 24 inches tall then flower them.

Today I changed my flood schedule. I had been flooding twice a day while they spread their roots. Once at 6 AM when the lights come on and once at 6 PM. The lights go off at midnight. Because they now have spread their roots, I programmed the ebb and grow to flood them three times a day. Once at six AM, once at noon and once at six PM. They have started showing new growth since I turned up the nutes yesterday.

I still have one plant that is basically retarded. The other 14 are all looking good and are about evenly sized.

i use ebb and gro with the lucas formula also, its a great system.
cant wait to see you trees...

Time for some new pictures.

The buckets have been showing roots out the bottom for a couple days and I have turned the PPM up to 600ish. The plants have started growing. I have one halide light and I dont want to add a sodium right now so I made some panels with Mylar on them and boxed everything in. This way I dont waste any light and the plants on the perimeter get lots of reflected light.

Tomorrow I change the solution.

PPM 600
PH 5.7
Temp 78
Solution temp 68

Looking good! How do you cool your lights? I run 3 1000w in my flower room which is a DR240 (8'x8') and it gets so hot that I have to use AC... It is getting colder outside now so hopefully that will change and I can ditch the AC but we will see...

That is a very good question. I am growing in an unheated basement and I draw air from a room that gets very cold. Last winter I ran a couple of crops with 2k of sodium with no heat problems at all. This summer I ran two lamps and did run into issues.

I probabally wont add the third HPS until about the 2nd week of flowering which is about a month from now. By then my basement will be very cold. If I have heat problems then I will cross that bridge when I come to it.

I have dealt with problems like that by asking here on the forum until I find an answer that works out. Pretty much everything I have learned about Hydroponics is from this and cannabisculture.com

Early next year I will get vented hoods for all of my lamps. That will eliminate that problem and allow me to start messing with CO2.

Nice. I run cool tubes and that takes a lot of the heat away, but it still gets hot in that tent... I am in the process of making a bigger flowering room that will include CO2... pretty stoked about that but I have to do some more research first... While running CO2 you can have higher temps so I probably won't need the AC anymore once that happens...

im doin 2 clones of blue cheese 2 puere gold and 2 blue venom(blueberryxwhite widow) in 5x4x8 room im using one 1000 watt hps for flowerin and i find out tha spraying the plant whit mineral water makes the temperature go down up to ten degrees
