appx water intake??

[sheist]

has anyone measured the amount of water taken in by the plant when they water it? i would like to kno this, as most plant would have a relative similarity in the amounts, and it would let me kno if i overwatered/underwatered..

i'm planning on using a spray/mist system.. most likely i'll be watering it manually.. best way to do somethin is by urself

I am assuming you are talking about hydroponics since it is in the hydroponic thread. Water intake depends on many factors, but the major factor is heat. If its hot as hell your plants are going to drink a shit load as their sweating it out. I have 4 plants that are using about 4 gallons a day. So a gallon a day for each plant. Those are White Widows in the 3rd week of flowering. Hope this helps.

holy shit.... i'ma be doin alot of sprayin... (*decides to fuck the manual way n go electric)
yea.. in regs, ppl usually just water it til the soil's most and its good for a while, and the water sinks to the trap area of the pot..

hydroponics use measurements. so i wanted to log.. but a knowing u use a gallon for each plant, thats pretty helpful.. when do YOU water your plants, and for how long?

I think we are on a differet page here man. Hydroponics is going to use a different amount than a soil grow. Soil grow, your going to lose alot to evaporation and run-off. You should post in a different area. I was quoting 1 gallon per plant for a bubbler system, where there is no evaporation of water, just from what the plant is (transpiring, perspiring) Whatever the hell you call it. But again, it has to do with the heat and humidity levels.

In hydroponics or dirt?

Hydroponics I run my drippers 24/7.

i was wonder the same thing as well to be honest, i am using nft and have set the system 15 mins on and 45 off....should i keep it on all the time?

NFT use more of a ebb & flow type of feeding schedule. You don't have a lot of room for roots to hang like most drip systems. NFT only having a few inches before the roots bottom out means they will be sitting in running water 24/7 and not have much of a chance to breath. Roots sitting in water run a big chance of rotting, or holding pockets of imbalanced nutrients in your tray.

Play with different feeding schedules, like 15-on 15-off or 30-on 15-off or 15-on 30-off record how they do with a few day's test. In about 10 day's you will know how that strain does with feeding.

Different strains react differently to different feeding schedules so trial and error on your part is required.

Also track the Ph with each schedule too.

ok zandor thanx a lot man you just saved me

ok, one more question now......the night has passed, got up and checked the plants.........to be honest here i had let's say a small problem with my EC because (the stupid ass that i am) i did not calibrate the EC meter right away when i bought it and had some nute burn on some plants....i did the calibration only yesterday to realise that my EC on both trays was 2.3 (a bit high huh?)....anyways after calibration and adjusting of the liquid on the tanks the levels of EC where stabilised at 1.5 at both trays with pH at 5.7 and 5.9 respectively....the nute burns have started dissappearing from the plants in question and all 23 plants look great..

now, i have changed the watering schedule into 15mins on and 30mins off and somehow it feels just right for this stage...i can clearly see the roots growing large into the channels that are located on the NFT tray and they look great....no signs of browning (rot) or anything unusual...also i leveled the trays a bit up so as they drain well after every watering as the rockwool cubes leave some hair from them , hair that goes straight to the drain hole and block it which in return does not allow the water to drain and thus transforming the tray into a ''swimming pool'' for the roots....
anyways, should i top the nutrient levels in case EC falls a bit? for example after tonight the EC has dropped by 0,05 in both tays (from 1.5 to 1.45)......i am going to change the water in the tanks on monday as it is scheduled for that day....pH is at acceptable leves at 5.9 and 5.8 respectively, no need to adjust that
i guess i will stick to that watering schedule (zandor thanx again) for the entire veg state and when i pass into flowering i will change it to 15mins on and 15 mins off. i suppose that the plants will drink more water then





take care

Ok I think what you are asking is if you refill the reservoir with nutrients when the level drops? Is that close?

You do a full nutrient change every 7-10 day's. It's safe if you use just Ph water on day 11 then on day 12 go back to nutrients. That will keep you from having lock up problems but it does use more water. If you can't do a quick flush after each water change that's ok you don't need to but it's a good idea if you have the water.

Now your EC or PPM will change after you put it into the reservoir and the plants use up some nutrients and deposits more back into the res. So the reading you take on day one is only good for day one. There should not be a change of more then a few hundred PPM points from any 24-hour period. Make a plot chart and track your PPM/EC you will see the pattern.

If the level drops and you need more water in-between changes then just use PH adjusted RO water to bring it back up to the normal line.


Does that answer your question?
