Here we grow again! I started a critical purple auto again for my third grow. I started the seed in paper towel again. Im 2 for 2 on that method so I figured I’d keep it the same. It’s from the same seed pack as my 1st grow so Im hoping the tendencies are the same. After this, I may never grow an auto in the grobo again. After doing one of each, I like the control and finesse that goes with the photo. Auotos feel like constant damage control until time of flower. Lol… I know everyone has their preferences but thats my two cents on it. Im really going it to “test the limits” of what they recommend for autos this time around. My 1st one kept growing so im going to treat it more like a photo (of course I cant control when it switches still and obviously I won’t switch the lighting). But im going to top it, use lst, lollipopping, supercropping, and hooks/cables to try to control it. I have a feeling that putting some extra stress on it will help it start flowering sooner or at least stunt its vertical growth enough to keep it from reaching the lights but I guess we will see.
Before starting this grow, I did a very detailed cleaning. I emptied the reservoir dry and removed the airstones. I soaked the airstones in hydrogen peroxide and I did a reservoir fill to 50% with vinegar water. Then I scrubbed the inside and drained it. Then I did a full fill and drain with tap water. Then I put the airstones back on after soaking for 2 hrs and did a fill to 75% with hydrogen peroxide and let the bubblers run for about 45 min. I sprayed the entire inside with hydrogen peroxide and did another wipe down and drain. Then another fill/drain with tap water. Then I let it sit for 48 hrs to ensure everything was dry. I will probably do that between every grow going forward.
I cleaned my sensors with a brush and cleaning solution from bluelabs and recalibrated before my 1st fill. If you are new, this is a must before each grow. You can get satchels of calibration solution from bluelabs or you can get bottles of other brands on Amazon or elsewhere online. Ive used both and they work the same. Ive found you get more bang for your buck if you buy bigger bottles though.
I’m excited to see the difference between this and #1
