So, its been 30 years since I grew, a lot has changed. I ask my fellow growers to please lead me to success. I originally ordered 3 northern lights feminized auto from seedsman. all 3 sprouted but 1 died after germination. The other 2 only made it to 2 weeks with the leaves under developed and twisted. They had root problems and died. Seedsman was kind enough to send me 5 zkittlez auto feminized. So here am at week 1 the pics are my babies at 4 days old. All 5 have sprouted. I have 1 in soil, and 4 in rockwool cubes. I am using a 1000 watt LED full spectrum light. I have zero experience with this light. I used fluorescents and regular light bulbs back in the day. I also had a metal halide, but most of my success back then was with the fluorescents. I'm experimenting with hydro this time. Here are pics of my setup. I have an air pump 4 watts with 2 air stones, some tubing and nozzles, and a water pump to circulate. I am trying a setup that has drip, and deep well. I plan to put my rockwool babies in there when they have 3 sets of leaves. I need advice on the lights distance. It seems like I can put them as close as 3 inches, but I opted for 6 inches cause they seem to like it. I worry cause I have no experience with this type of light. Anyway I look forward to any advice from the pros
I don't dare give fertilizer nutrients to the rockwool ones cause they are so vulnerable. My question is how moist should I keep the rockwool? The leaves are curling slightly is it from the rockwool being to wet? Advice on rockwool??
I would suggest backing your lights off to 24-30". You should go by the manufacturers recommendations. Are they drawing a true 1000 watts for both of them or is the true wattage draw more like 300 watts each. If the light is too strong/intense you can actually stunt the seedling/plants. Using a PPF/PAR meter is the best way to know how intense your lights are at different distances if not your just guessing.https://horticulturelightinggroup.com/blogs/news/horticulture-metrics-par-ppf-ppfd-dli I would start high then lower them a few inch's every 4-5 days especially if you see them stretching for the light. I'm not going to B.S. you I have no experience growing in rock wool so I have included a link. https://www.alchimiaweb.com/blogen/grow-cannabis-rockwool/
I will recommend two things for you 1st is to add a cool mist humidifier to the grow space your humidity needs to be in the 65-70% range to avoid an issue with LVPD ( leaf vapor pressure deficit ) until your plants have grown a good sized root system this has to do with plant transpiration which allows nutrients to properly absorbed through the root system. The reason your seedlings leaves are curled is either light stress or their trying to conserve moisture do to the lack of humidity. http://www.just4growers.com/stream/temperature-humidity-and-c02/vapor-pressure-deficit-the-hidden-force-on-your-plants.aspx 2nd try to keep the ph of your water/feed solutions 5.6-6.2 ph for hydro. There are way too many opinions on ph for hydro but it's shown that the best nutrient absorbtion is in that ph range. You can also check out my current grows there is some information in week 2 about PAR and LVPD👍
Worked out the light issue. I am down to 4 plants now 3 in soil 1 in DWC ( no photo yet ) thank you @Philindicus who set me straight on the lighting distance
No some growers think 24 hrs are going to make the plant grow the fastest. But most growers will tell you your plant needs a dark period just to rest and recover from working all day in the sunlight. I agree best and recommended light cycle for autos is 18/6 or 20/4. I prefer 18/6. You can save on electricity with 18/6 too.
almost 2 times as big as last week, flowers are showing so next week will be 1st week of flowering. heavy branching this week. I cant figure out how to add the nutrients I am using. they are all organic and added to the soil during preparation. dr earth organic and jobes tomato and vegetable. also adding super thrive to all water at all times. I also brew in a 5 gal bucket all the mentioned fertilizers with a air pump and water 2 to 3 times a week
Almost finished!! I had to harvest the tops of 1 of the plants, it boke when moving the plant around. I got about a half ounce dried that is now curing. I think next week will bring the final harvest!!😝
Ok these are Seedsman Zkittlez Auto I got as a replacement. The strain is awesome. This is happy weed that tastes great. I highly recommend. 3 plants have given me 9 ounces WET, so I figure it will be around 4 or 5 when dried. I will update when the product is finished being dried and cured
