flooding? as in flooding the bed so as to submerge the roots entirely? and then my next question - flooding every 3 hours during light cycle, is it the same in veg (18-6) and budding (12-12)? thanks for all the help! Also is it critical to have 2 hps or can it just be 1? atm i realli only have enuf space to experiment with 2 lights and i would prefer to use 1 of the lights to veg and 1 for budding that way i break down the cycle into a 2 cycle, less wait time =)

Yes you will have to flood the bed (tray table) so that the roots get nutrient solution in order to propel the growth of the plants. Make sure that you include air stones in your res to oxygenate the water. This will also improve growth as well. You may also want to add 35% hydrogen peroxide to the water before adding your nutrients & ph.
Yes you will only flood every 3 hours during the light cycle. Some growers flood 1 time during the night cycle as well. In Veg you can keep the same schedule or flood every 4 hours. Keep in mind that every plant is different as well. If you see the plants are getting over watered then lower the schedule.
With lighting for a 4 x 8 table I would do 2 600s, 3 600s or 2 1000 watt hps lamps. Do not attempt this grow with 1. Youll be wasting your time. To tell you the truth if your attempting sog then go straight from clone right into flower. You can veg for 7-10 days if need be but any longer youll have a jungle.
Take a look at the pic below. This grower has 161 pots in a 4 x 8 in 5x5 square pots. He uses 2 600 watt hps lamps on a light mover. The yield is 3lbs 10oz dry weight every harvest. There are some commercial strains that will average more. Imagine putting two 1000s on the 4x8 or having 2400 watts with two 4x8 tables. 1200 to each table. thats 7lbs per harvest.

Also remeber when you start to flood your table that you have to have the timingof the flood applied to the system. Some pumps may take 5 minutes toflood the entire table & others may take 15 mins.

also someone asked a question awhile back that wasnt answered about alkacelzer and water. can this mix create co2 for the plants???

Remove from the heater asap. Keep seedlings in a cool dark place until they sprout. Do not expose to light until they sprout. Try to get a heating mat & set the temp on the mat between 75-80 degrees. The carbonated water thing is old school. Your not at that stage yet. When you get ready get oneofthose cheap CO2 Boost buckets. Theyll last from 60-90 days I think. Distilled water can be used, but as proper practice still read the ppm & ph. Good luck.

how many plants is good for a 400 hps.

35% hydrogen peroxide will kill any bacteria in the water & will also provide excess oxygen to your roots. The best brand to get & what most growers prefer is Grotek H202 (Google it). I believe it is 2ml per gallon. The directions will be on the back of it. Make sure you properly mix it with a wooden spoon or what ever is your choice of mixing your supplements & nutrients.
No problem Im happy to help. It helps me to stay sharp as well.

The lamp should be 12-24 inches from the plants first of all. You can go by this or by the below chart. Depending on whether your growing bushes or SOG.
400 watt hps: 2.25 x 2.25= 5 square feet
400 watt mh: 2 x 2= 4 sq feet
600 watt hps: 3 x 3= 9 sq feet
1000 watt hps: 4 x 4= 16 sq feet
1000 watt mh: 3.25 x 3.25= 12.25 sq feet

The only other way is to get air cooled lights so that the heat does not disrupt the temps in the res.

No problem, happy to help you anytime
hey southflorida, ive been doing research on co2, and id love to give it a try unfortunately i have funding only enough for 1 burner and monitoring system atm. I was wondering if co2 is better used in the baby/veg state or in the final budding stage and if i were to use co2 with the baby/veg would it be harmful to not use co2 in the budding stage after the plants have been in a co2 rich environment? Also if u know of any good brands or could recommend anything would be awesome! maybe a monitoring system too?
lol sorry for all the questions and tyvm for all the help uve been so far.

CO2 can be used for veg & flowering. Make sure to keep your ppm at 1500 thats really the only way CO2 will be effective. Also remember that fans can not exhaust while CO2 is being run. It will just waste the CO2 enrichment within the growroom. CO2 works best in a sealed growroom. But for this you will need aircooled lights or an ac within the room.
