thanks man, growth is really nice in both tents atm.
they wont grow worse with 2-3C more, but they perform with 23- 24C also quite nice, which isnt a terible low temp either.
i would really need to think a bit what i changed.
changed nothing on the light setups in the last time, but i gave up the concept that a plant need to take a certain wattage or ppfd at a certain time.
i follow the priciple in veg that a plant needs to pray most of its time otherwise i dial back the light.
this way i get happy nice plants,i always take measurements with the spectrometer and have some numbers saved in the head i know beeing quite save.
its doable under leds, you just need to realize that these led units push out so much more light then cfls do, basically about 3 times.
the suqaremter tent i vegged with below 100w, more like 80-90.
for the flower cycle i still need to play a bit, there they pray all the time anyway (even or especially with too much light),i have the one tent at 1000ppfd since a few days and think its maxing them out, maybe 900 is better for me atm.
i changed the medium maybe 3 times in a year.
atm i use cocos chips in the smaller tent and cocos chips mixed with finegrain in the square meter, its still a expermient but roots are great,
makes the whole thing easier llikely..
this is a good week old picture., plants are in veg.
fertilizer wise i didn changed much.
still using my saltbags.
i play a bit with ratios and maybe change forth n back between 2 basesalt bags, one is 3-17-36 the other is 5-20-30 plus calcium nitrate and magnesium sulfate, atm i just use the 5-20-30 as cocos have so much K anyway.
i use RO water, so i give always a bit epsom , 1-2g a 10l.
in veg i try to give quite some calcium nitrate in flower i dial it back a lot and give more basesalt instead which contains a lot MKP, i do have a bag MKP too but may use 5g of it a run.
i also use bennies/seaweed in cocos but not much, i autofeed just plain salts
i do autofeed the tsmaller ent which is in flower this run, 3 times a day when lights on, EC not that high, sensitive plants maybe just 1.3 EC most of the time.
EC range is maybe 1- absolute max 1.5 pure nutirents.
@KonopCh the tent is a sqaure meter pretty exact.
growth was really good for this month all went well, would say from the partycup they came till filling out the 3 gallon bags like above, 3 weeks.
but they are for sure 8 weeks at least, 2 weeks from fresh cut to really rooted cut and maybe another 2 weeks in my veg box slowly growing on standby.
