very nice pic!! cant help but to think of the outcome
I add about 20% perlite mixed all together. You can get a 8 week strain veg for a month and there is your 90 days. Are clones an option?
how does the ventech kit perform ? hopefully with the ventech speed controller i can reduce the noise on the 4" booster fan if it gets too loud. Thanks for your input, is good to know the 4" ventech kit will suffice!!
Autoflowers get lucas formula every watering.
Regular plants can too, but I would start with every other watering. Soilless mix is different than soil, it leans more towards hydro. I can feed every watering without salts building up to the point of affecting the plant, but I have ample runoff, and the plants I grow tend to be hardy nute hogs. They also don't go past 75 days (65ish on average)
Sensitive plants may not like getting fed every watering, especially if you have very little or no run off. Also if you have longer flower times, you are more at risk for salt buildup. Some people feed 1/3 strength nutes every watering, others feed full strength every 3rd watering. And most people just feed every other watering.
I feed every watering and every so often (when I feel like it, or the plants start to claw, or show some random signs which is rare for me) I will use straight water with ample run off. But I have gone full cycles without giving them plain water.
There have been times when I've used the maxibloom powder and did not completely dissolve it. No problems. (with autos, can't remember if regulars also got it, I've used all 3 versions of lucas)
The fan blows really nice, the filter is good quality and comes wrapped with plastic under the foam to keep the carbon fresh make sure you remove it.
With a speed controller you should be okay on the noise, when i kept mine around 50% it was super quiet, but when it got hot i had to ramp it up and it was just too loud for me, i upgraded to a vortex s line, much quieter overall.
And to answer your other questions just put the fan and filter in the tent and have it sucking from the filter and blowing out of the tent, the intake ports on the bottom will suck in inherently due to the air being removed. fans blowing into the tent will create positive pressure, which can hinder heat removal.
I would personally start your first run with clones then switch to seeds if you want, clones are so much easier and if you can get them from a shop you might as well try it your first time, that way you can spend your free time learning about all the other things you need to still figure out
If you're doing autos then you might not want to do any LST. You only have a certain amount of time before the plants are done so any LST will require at least a little recovery time that will not allow for maximum growth. A lot of autos have very short growth times and therefore don't get that big, so trying to fill out a scrog might be a waste of time as well. Also, due to the short growth time of some autos, a 3 Gal full of Ocean Forest might take it the whole way through so you might not have to add synthetic nutes. I just got done with Sweet Skunk, Dark Devil, Amnesia XXL and Sugar Black Rose. All of them are autos. I used Roots Organic soil in 2 Gal pots and topdressed lightly with amended soil. They all have their strong points but the Amnesia and Sweet Skunk are my favorite! Probably wouldn't grow the Sugar Black Rose Autos again. Happy growing! Let us know how it turns out.
