Hi guys My sprouts are very slow, they look less than 10 days when they're 16, they're on led 90 watts since 2 days, shall I stat feeding nutrients ? Or are they still young ? What could cause this ? Thanks
Looks like they need more light, the stems look thin. I had a seedling with stunted growth because of too little light.
clarebearr pegs you, bud, seedlings have stretched far too much ... they need light closer, much closer.
What in gods name am I looking at there? lol Is that linoleum flooring? I'm guessing you used that to cover up something you didn't want to put online, but if that is actually part of your grow, I would recommend replacing it with a flat white surface, which will reflect a lot more light. I agree with the other guys. They need more light; or move the light source a lot closer. Get an indoor/outdoor thermometer that can use to log high and low temps. You can put the outdoor probe right at the level of the top of the plants and monitor the max temp the light subjects your plants to throughout the day, which allows you to put the bulbs as close as possible without damaging the seedlings.
Lol very weird to look at indeed.. They need light as said before. 20 seedlings, 90 watts... 90 watt rated or actual draw? Plants need 100-150 each and your giving them less than 10% of that
Over-watering, bad genetics, lack of light, too hot, too cold, PH too high, PH too low, etc. Anything could cause them to grow slowly.
