As a first time grower would i have a better grow (in your opinon) with
a hempy or with soil, reason i ask is only soils i can find are pre nuted booshat
I've fucked up both ways! They both have their pitfalls. But I like hempy. Here's why:
Number 1 noob error is overwatering. YOU CAN'T DO THIS IN HEMPY. It's not a problem.
Number 2 noob error is overfertilizing. This is easy to do in any medium, but a lot easier to rectify in hydro or soilless, because you can flush much, much more thoroughly.
Lots of people here have grown successfully with pre-nuted soils like Miracle Grow. I haven't done it, but I think the key is to not use other nutes. Most people who have problems with MG are adding other MJ-specific nutrients which, combined with the MG, result in overfertilization. I'm basing this on threads I have read here, not on personal experience, but the same story comes out over and over.
I would say get a soil grow under your belt. Go ahead and use MG or whatever you are finding (I'm sure if you look a little more, you can find clean, unjuiced potting soil, though). I would mix that about 60/40 with perlite to increase drainage and help keep you from overwatering.
Fine out about the water you are using. If it's tap water, find out from the city what its characteristics are (this shouldn't be hard, or suspicious); pH and TDS (total Dissolved Solids). If you water's pH is between 5.8 and 7.0 and TDS is under 150 ppm, you can use that. If not, consider using RO water.
On the other hand, my first grow was in shitty potting soil, using really bad city water and no understanding of plant needs. The three females I ended up with looked like shit, never smelled during flowering and were kind of puny but I ended up with over 4 ounces of cured, hard nugs which was some of the best smoke I'd ever had.
Anyway, your first grow is going to be a big learning experience. Plenty of folks here don't even get to harvest that first time. Keep it simple and don't be too hard on yourself. Most important, don't love your plants to death!
