I have had wild fluxuations in humidity and temp, before i got the latest humidifer, it could be as low as 10% and struggle to keep 50%, its still wintertime here, and i need to keep the window open for temp controll, and the plants have of course suffered from this

now I have the humidity around 50%, but still a bit hot,even though abused, three of them looks ok, but one is struggling

the plants are about two weeks, the smallest one about one

this is my Big Bud

I dont think i have overwatered so gave them some water with seeweed today, most plants also show yellowing of the "main vein"

any idea of why this is? is it just the heat/humidity stress ?

Any input welcome :) have a nice day

Slow the extract fan down or off... these tiny plants dont need much fresh air. So no need to exhaust much. This will help keep the humidity up. A cheap heater and a wet floor will help too.
thx mate, i dont have a controller yet, but i guess there is enough circulation, just with the open window and the table fan, so could turn it off until they need it or start to smell

the light is about 20 inches from the plant, th rh about 50, Heat varies a lot, but its on the high side like in the 80 + side
Stop it varying. Keep it at the same temp. Those droopy leaves would indicate to me that the they are either over watered or they are not transpiring enough to pull the water up.

As its soil.. make sure you are letting it dry out for these plants.

thanks mate, I've raised the lamp a little bit, turned off the extract fan, so should be able to keep stable temp and humidity

but do you measure temp at the highest on top of plants, or in the grow tent out of the light ?

and have much water does one give a two week plant if you water say like every other day ?


before watering with a little seeweed extract today, i havent watered since Thursday, then I gave them aprox 0,5 liter, today i gave them half that, I have been sparying the soil quite often to try to keep the humidity up. The first inch of the top layer was dry today

Stick you finger in 1cm below surface.. if its damp dont water.

Stop spraying soil as this will stop you doing the above.

Spray the floor and maybe a tray of water by intake. If you have a heater then put a tray of water by that too.

I would advise getting an inkbird thermostat. Cheap as chips and work really well.
