Hi All. i have turned a large fridge into a grow room. it everything i have read up on - external fan with carbon filter, inlet fan, internal fans, humidifier on a sensor, heater on a sensor, light on a timer. all set up for what i have read. heat during lights on set between 24 to 26, heat during lights off set between 18 to 20. humidity for seedling growth set between 67% to 72%. lights on 18/6 cycle. i have tried 2 lights at different heights with different intensities. i made a few mistakes with my first 3 attempts.

FIRST attempt the outside temperatures were too hot and i had trouble balancing the inside temp and over heated the seedling stunting it, it stayed like a 1 week old seedling. ( i made the necessary changers to the grow environment)

SECOND attempt i over watered it and the soil was to heavy. it stayed like a 1 week old seedling ( i made the necessary changers)

THIRD attempt i started light nutrients at the end if week 2 and burnt the leaver. it was still small when i did that but with time managed to get it to grow more it is now about 60mm tall and 60mm wide but has stopped growing again. it is in week 7 now.

FOURTH attempt I discovered the light i was using had veg and bloom settings i halved the total umol of both switches since i only had the veg switch on. but found out it was still giving 600umol. so thought excess light could also be an issue (i got a new with adjustable dial) this time i used an app and set it up so the seedling would get 300umol. after 3 weeks the seedling only looks like a 1 week old

FIFTH attempt on line i have seen 100 to 300 umol for seedlings and i have also read 5000lux for the first week then increse it by 5000lux each week so i thought the 300 umol did not work so i would try that. so i set up the light to give 5200lux = 90umol, on day 1 the seedling was 25mm tall on day 3 it was 40mm tall and on day 4 it was 60mm tall. as it was stretching i have now turned the light up to give it about 8000lux = about 130umol that is today

i still have attempt 3 4 and 5 growing 3 and 4 just are not doing anything they are getting 9000lux and 10000lux

I am growing in a 20% top soil - 30% propagation sand - 50% coco coir mix

any help would be appreciated.
Could it be an issue with the top soil? it is a new bag of top soil from Mitre 10
would just growing in coco coir and propagation sand be better.

This is my first time on any blog and first time growing
Thank you all for your time

Hi Oldchucky & Phytw
Thanks for your thoughts. i just got a bag and carefully transplanted the 3 week old seedling, it had a very very small root system for being 3 weeks old. i watered it around the outside edge of the pot. and turned the light up slightly. this one is now getting about 200umol - 14000lux

I also transplanted the 5 day old, its root system was bigger than the 3 week old. i also watered it about 60mm out from the seedling and sprayed it. it is now getting about 180umol - 12000lux. as this one was a little stretched i planted it with only half the stem out of the soil

How long do you think they should take to recover and start growing again?

Thank you for your reply. i taken some photos. the 7 week old as far as i could tell never looked overwatered (i now know what that looks like i think) it suffered nutrient burn at 2 1/2 weeks old but was very small at that age. then i got it to recover after just over a week and it grew again for about a week and then just stopped again and has been like this for almost 2 weeks.

the 3 week old was looking good until yesterday. the top 15mm of the soil was dry and it had been 5 days between watering the last water was plain water PH6.5, so even though it was small it was almost 3 weeks old so i watered it with a nutrient mix giving it approximately NPK 4:1:1.5. and now for the first time it is looking over watered to me. this seedling i was letting it dry out a lot between watering as to not overwater it

The 5 day old seedling i really want to grow so i am reaching out to see what is wrong. the only thing left i can think of is maybe there is a problem with the 20% soil

I am letting the soil dry out the top 15mm or more and letting it get below 55% on the soil meters before watering. i am using PH6.4 to PH 6.6 plain water for the first 2 to 3 weeks

each plant has 1 photo taken under the grow light and 1 taken under a torch flood light. the mist you might see is the humidifier mist
the 7 week old was watered late yesterday. the 3 week old just over 1 day ago. the 5 day old has not been watered since the seed was planted after germination. but it has been sprayed 3 times each day that has been keeping the soil moist

Any and all help would be appreciated as i only have 2 seeds left now
