Even the best grow lights can’t compete with the sun but that being said, there is such a thing as too much light. I would imagine though that heat is more the problem with indoor growing.
Does the light have dimming capability? I’m currently at 30" above the plants at about 55% brightness and the growth rate seems pretty good to me. You can also raise or lower the light to control the intensity, but as the plants grow there’s less wiggle room obviously but in flower is when you WANT as much intensity as they can handle.
Humidity is very important in the early stages because of the limited root structure. They need the extra juice in the air as the root system expands and as you move into later stages of growth humidity is lower and lowest during bloom to protect from bud rot. I don’t know all the percentages off hand but Roberts guides on the site have all the info in them.
I did pull one of the timers out of the strip yesterday and when I plugged it back in the times were still in there. It was only out of the plug for a minute or two so I’m not sure how long they will hold the info.
I’m running my fans and exhaust on a timer but I let them go for 20 minutes after the light turns off just to clear the last stale air out of the tent. Apparently some growers will set up the ventilation to come on and run for 15 or 20 minutes a few times during the dark cycle.
My thermometer/hygrometer can connect to the phone via bluetooth and maintains the info it’s collected through the day, week, month or year. You can set upper and lower parameters for both temp and humidity and it will send you an alert in either case if you exceed or drop below your set range. The advertised BT range was a joke and I wish I could find a wifi enabled unit. If anyone knows a accurate unit with a reasonable price tag LMK. I haven’t figured out how to, or even if I can export the data, but the graphs look cool and on the humidity scale you can even see every time you open the tent as it takes a giant dive.
Speaking of opening the tent, anyone running a cam in the tent for remote observation?
I’m really considering it because as a doting dad I want to check on the girls constantly and they’re probably getting tired of seeing my bloodshot peepers staring at them. LOL!
My eyes are red because I’ve been up all night reading on ILGM and of course that morning bowl of Gelato! LOL!
I’ll be doing the clear cups inside the red solos next time around. I like that being able to actually see the roots as they’re growing. I just did a garden cell tray thing I had left over from last years tomato grow. I’ watching every day for any signs of roots at the bottom but alas what I thought was my first root was not, just part of the mix. Bummer!
Hopefully others will chime in but I would thing for the vacation maybe you could intentionally over water them a bit and they’ll be ok? Maybe?
Of course the res on the humidifier won’t last that long but if it’s auto-shut off at least the first day or so you’d be ok there. Could always leave a bowl or 2 of water in there and let it slowly evaporate under the lights. May not maintain the exact humidity you need but better than nothing. At that point you’ll be in veg and won’t need the higher levels the seedlings require.
My seeds, all from ILGM.
NYD = New York Diesel, SSK = Super Skunk and GDP = Granddaddy Purple.
Maybe you could contact customer service and they can tell you which numeric code corresponds to which strain.
I’ll definitely be doing a homogeneous grow next go around. Maybe from clones off one of the current crop.
I have some experience cutting and rooting clones from other plants including Azaleas and roses. Weed CAN’T be tougher to clone than those. LOL!
Ugg - why did I put off cleaning house until today? What a way to entirely ruin a Saturday!
Happy Growing all and if we could get a answer on that perlite question that world be awesome. I’m going into week 3 and will transplanting soon!
what a bummer, well I hope you find out what strains are what. The tent, 24x48x72, is a good tent! I had 8 in there veggin at different veg cycles, getting confused on what is what, being on meds. Anyhow, with either tent you have coming, you can grow 3/4 easy til 4 ft tall if you like. Or you have multi strains to see which 1 is going to give fatty fist size buds! Well good luck on your grow, I’ll be in the background, but hey ty oh got this. Btw! Harvest time see mmmm pretty
