Penguinfarmer Posted March 10, 2022 Share Posted March 10, 2022 Does it make any difference if you water when lights go on, or start watering 1h later? I remember reading something about this but coulnd't find it anymore. Feeding multiple times a day and using small 4.5L pots, so they get pretty dry during night. Might have to put one watering on dark cycle later. 2 Link to comment Share on other sites More sharing options...
catweazle1 Posted March 10, 2022 Share Posted March 10, 2022 (edited) Are you watering to runoff? You water when you like. Edited March 10, 2022 by catweazle1 1 Link to comment Share on other sites More sharing options...

catweazle1 Posted March 10, 2022 Share Posted March 10, 2022 (edited) Pure coco? @Penguinfarmer How big are the plants? Water as often as you need to, irrespective of time of day. It's not like a soil routine. The important thing is to not have it dry out as that will concentrate the nutes in the coco and you'll be seeing dark leaves and burnt tips.

Penguinfarmer Posted March 10, 2022 Author Share Posted March 10, 2022 @catweazle1ye pure coco, 4 plants fill 4x4, and setting an automated feeding routine now so thats why I was asking. Been doing so for few runs but want to dial it in perfect Hmm that might be why my runoff EC jumped. Maybe I was handfeeding too few times since they drank like 500-600ml per plant each watering in 4.5L pots. 3x a day. No burnt leaftips though so it didn't get too bad. 2 Link to comment Share on other sites More sharing options...
Unc Flawless Posted March 10, 2022 Share Posted March 10, 2022 Dry backs are the way to go in the early stages of potting up to a bigger size pots/fabric, this encourages the roots to fill out the your medium in this case coco. 4 Link to comment Share on other sites More sharing options...
Penguinfarmer Posted March 10, 2022 Author Share Posted March 10, 2022 @DCC Yes I did this, now the pots are very filled with roots. I am also wondering how much to water each round. I've been doing pretty big waterings so far. Someone was explaining that you should water 250ml in ~4L pot per watering. Do you guys agree to this? It means I will have to water ~6 times a day now and plants arent even at biggest stage yet. 2 Link to comment Share on other sites More sharing options...

I think you may need to pot up, if your watering this frequently in 4 L pots?, if you have been doing dry backs, them pots should be full of roots and ready for some new boots. 1 Link to comment Share on other sites More sharing options...
Penguinfarmer Posted March 10, 2022 Author Share Posted March 10, 2022 @DCC Naa man, this is working for me. 4.5L are the final pots for them. Small pots, big growth 3 Link to comment Share on other sites More sharing options...

I water right at lights on and then 6 hours into their cycle and they’re fine. I’d avoid watering just before lights out though. I put 1.3L through my pots. Which is almost half the volume. Though this may seem a lot to some. Might even perturb others but it’s the only way I get in and out EC’s how I want them. It’s only me first coco grow though mind. I’m no professional I just know what’s worked for me on me first go. This is very dry imo. I am worried my 600ml per 4.5L pot is too dry. Earlier it might be ok but when roots have established I feel its very dry. You might want to look into giving them atleast 4 waterings a day, I feel this is when they kick into higher gear Edited March 10, 2022 by Penguinfarmer 1 Link to comment Share on other sites More sharing options...

You shouldn't water during lights off as your plants aren't transpiring. You should water 30 mins - 1hr after the lights go on - a good way to tell accurately is to watch for the relative humidity spiking after the lights come on - this is your plants starting to transpire and thus indicating its time to water. A good way to tell if your plants need additional fertigation is by keeping a note of input and output volume, and input and output EC. If the output volume decreases, and the ouput EC increases, add more fertigation events. 13 Link to comment Share on other sites More sharing options...
Penguinfarmer Posted March 10, 2022 Author Share Posted March 10, 2022 (edited) @mikeydoughnut Yes its fine, there is as many styles of grow as there is growers. @GSZZ I might have to give them atleast half a watering later on, during lights off, so they don't get too dry. Plants are pretty big for 4.5L pot. This might be the same reason I remember reading you should wait ~1h before watering when lights go on. Edited March 10, 2022 by Owderb Quotes removed.

His pots are prob too small or it's like the Sahara in his tent. 1 Link to comment Share on other sites More sharing options...
Penguinfarmer Posted March 10, 2022 Author Share Posted March 10, 2022 Jeez there is no fucking need to get toxic in here. Its not sahara in the tent either. Plants are supposed to fill the pots completely. Then they dont need much time to drink so much that pot is light. Not dry, light. Lets say I water last time 2h before lights off. At morning they are LIGHT and I dont want to get salt deposits. I am using small pots on purpose and they are not too small. 2 Link to comment Share on other sites More sharing options...

Unless someone else has done the same thing as you, you will have to learn the way empirically. Your question is like saying "How long is a pieceof string?" There is no sarcasm or ill-will intended in this post. 3 Link to comment Share on other sites More sharing options...
