Hi guys I started growing 25 October sowing three TD and one AutoMazar. October 28 came out sprouts from the rock wool except for the broken seed I sowed in any case (it was broken in Dutch Passion's bag).I write some data about my attemp of growing in DWC.
Grow room 80x80x160 CM
Lamp Agro 250w (but I have also a 400w ready for the occurrence)
1 Pot 21L
1 Pot few liter
Air pump to oxygenate res
Water pump
Some fans.

I start making res with an EC 1.0 and Ph 5.8 using Advanced Hydroponics of Holland Grow,Bloom and Micro.Also root stimulator and ph regulator.
RH oscillates between 40-50%
Room temperature oscillates between 20°C (lamp off) and 26°-28°C (lamp on)
I don't have an air extractor and carbon filter yet but I will later.

Here some pics:

if you notice something strange like spots (which they are maybe because I sprayed them a little bit with root stimulator solution at the beginning) or curling on leaves(which they are and I think bacause the lamp was too close(30cm) to the plants but now is more distant 50 cm and in a few days I hope to fix this issue)or trouble in growth or anything else, Advise on how to move. If you need something to know that help you to help me, ask and I'll answer.

Very nice,btw TD's can become she monsters.If given the right space, and grown right it is a real producer.Even if you arent a pro, it will give you nice yields of pretty powerful smoke.Good luck on your grow.Keep everyone posted.I myself am new and cant figure out how to post a grow on the "new forums" area.I just have a album.
 
Howdy Borax, welcome to AFN! :smokebuds:

You're in for a real treat with those Dutch Passion genetics, my friend. There have been some mind-blowing grows of both of those strains on here recently. If you haven't already, have a read through the threads of member "seymour-buds". He does some damn fine DWC work and has kept detailed journals of his grows:

Day 16
Hi guys! Yesterday I checked my res and the Ec was 0.98 and Ph 6.7 and some leaves of TD appeared to be limp so I make a fresh res EC 1.0 and Ph 5.8. and the leaves are back straight. Now even if the value of EC is not reduced a lot, Maybe is it time to increase the EC? I notice some spot(much more on AM than TD) like a lot founded on the web and I think it is some deficiency.What do you think?Room temperature oscillates between 20°C light off and 25-28° light on and RH 40-50%.I ask to you another thing...when we are talking about the value of the EC (eg EC 1.0 ), it means that we have to include in this value the EC of the tap water?I mean EC water 0.4 + EC nutes 0.6 so total EC 1.0?Or do I have to reach the total EC 1.4?any comments and advice would be appreciated.

Day 18

Some trouble with babies posted here(if you can help me):https://www.autoflower.org/f34/automazar-think-different-spots-curling-limp-13741.html
I'm trying to solve the problem with fresh res at Ph 5.6 and EC 1.1
Today I checked last res and Ph remained stable at 5.8 and EC 0.66(I suppose they are eating and growing).

I think roots are not growing so much.I use 1ml/1l of root stimulator "Advanced Natural power".
 
Day 22

AFN Hello! I realized that the meter pH and EC were out tare and I have ricalibrated them,so I think all the previous results are a bit wrong.the girls seem to grow and they seem to be recovering from problems.I changed the regulator ph and I'm using nitric acid at the moment(previously it was phosp).I separated the two big plants so they now have a bucket each ... I noticed good changes already, also in the little one.Roots have no problems.I done some leaves tucking to expose the site bud.The girls not clearly show sex but it will take a little I think.Both plants are at EC 1.3 and pH 5.8.Temperature is more or less 25° and RH 35-45%

Great grow so far!!
 
Hi AFN!I've always known ... grow a plant in DWC is not easy, but is not impossibile. I switch to Nitric Acid so I think it should be in grow.My problem now is to fix pH value because it increased in only 4 hours by 1.0-1.2.I had not so much incresing with phosphoric acid.Now surfing in AFN and reading something about pH issues, my hypothesis is that it is the presence of algae or something like that.So I made a fresh solution without putting root stimulator at EC 1.55 in AM and 1.65 in TD(maybe is an hazard but I follow doses on the bottle:15ml grow,7.5 bloom and micro) and pH 5.7.Also I clean and covered the buckets and all the pipes with aluminium foil to don't feed with light any algae if present.In a few hours I will check values and I hope to find no bad changes.
